Nitrous Oxide (N2O) is a colorless, odorless inhaled anesthetic that has been used for centuries, particularly in the surgical world. Mechanistically, it can induce euphoria, anxiolysis, and intoxication via NMDA receptor antagonism.During the late twentieth century, nitrous oxide was increasingly used recreationally due its accessibility and perceived benign nature.The modern day slang term for nitrous oxide is “whippets” – which tends to refer to the canisters that contain this agent and are frequently used as whipped cream foaming agents.Despite the legal nature and benign perception of nitrous, frequent use can lead to lasting and permanent neurologic effects. 🧠 How Nitrous Oxide Causes Toxicity Nitrous oxide toxicity results from its ability to oxidize the cobalt moiety in Vitamin-B12, thus leading to a functional B12 deficiency, despite adequate consumption and absorption.1Functioning B12 is needed as a cofactor for methionine synthase.2 This enzyme has two critical roles:The conversion of 5-methyl tetrahydrofolate to tetrahydrofolate; tetrahydrofolate is essential for the synthesis of our DNA.And the conversion of homocysteine to methionine; methionine is needed to maintain the integrity of the myelin sheath of our axons.As a result, nitrous toxicity leads to: a megaloblastic anemia and demyelination of both the dorsal columns and the lateral corticospinal tracts (also known as subacute combined degeneration). 🚶‍️ Clinical Manifestations of Nitrous Oxide Toxicity These patients will have a combination of both upper and lower motor neuron symptoms due to demyelination of the dorsal columns, lateral corticospinal tracts, and peripheral nerves. As a result, the following may manifest:Dorsal Columns: diminished sense of proprioception, vibration, and fine touch.Lateral Corticospinal Tracts: upgoing plantars, hyperreflexia, weakness of voluntary distal muscle controlPeripheral Nerves: numbness/tingling and weakness in a glove and stocking pattern (symptoms that start initially in the feet and hands that progressively spread proximally to the ankles and wrists)Taking all of this into account, patients may present with difficulty ambulating, positive Romberg sign, dysmetria (difficulty with finger to nose or heel to shin), upgoing Babinski reflex, and decreased strength and sensation in a glove and stocking pattern. 🔍 How to Diagnose Nitrous Oxide Neurotoxicity History is key! As with a lot of pathologies in toxicology, identifying the exposure will expedite management.A thorough neurologic exam will narrow the differential – with a particular focus to fine, peripheral motor and sensory deficits, dysmetria, proprioception, and ability to ambulate.Magnetic resonance imaging of the spine may identify enhancement and/or edema of the dorsal columns, specifically on T2 weight axial imaging – sometimes referred to as the “inverted V” or “inverted rabbit ears appearance.”3Serum B12 concentrations may be normal as the issue is with a functional deficiency as opposed to a vitamin absence. However, patients have elevated concentrations of both homocysteine and methylmalonic acid, both of which are metabolized in the presence of functional B12. 💉 Management of Nitrous Oxide Toxicity First and foremost, cessation of nitrous oxide abuse is crucial to limit/prevent toxicity.While there is no universally agreed upon treatment regimen, supplementation with intramuscular B12 is recommended.Approaches vary from daily or every other day injections until symptoms improve at which point injections can be spaced out to weekly and then monthly.Physical and occupational therapy may be needed depending on the degree of functional debility.It is important to note, that depending of the severity and chronicity of toxicity, some proportion of patients may not fully return to their baseline. 📌 Take-Home Points Though legal and seemingly benign, nitrous oxide abuse can lead to permanent neurologic dysfunction.Nitrous oxide toxicity can affect the dorsal columns, lateral corticospinal tracts, and peripheral nerves.Thus leading to a constellation of both upper and lower motor neuron deficits, particular in a glove and stocking pattern: deficits in proprioception and fine motor skills, positive Romberg, upgoing Babinski, peripheral numbness, tingling, and weakness.Magnetic resonance imaging may identify symmetric high signal intensity in the dorsal columns.Treatment includes B12 supplementation and physical/occupational therapy as needed. 📚 References Long H.

  From a 10-bed lying-in hospital to Handel's Messiah, the Rotunda Maternity Hospital has operated continuously for 281 years. A Nurses' Week story. Summary Across the street from Danny’s Dublin hotel stood a large white institutional building with no signage. It turned out to be the Rotunda Hospital — the oldest continuously operating maternity hospital in the world, delivering babies in the same building since December 8th, 1757. Surgeon Bartholomew Mosse founded it after losing his wife and child in childbirth, trained as a midwife in Paris at a time when physicians were penalized for practicing midwifery, and returned to Dublin determined to build something that didn’t yet exist. The first version had 10 beds and delivered 190 babies in its first year, with one maternal death. Unable to raise money for a larger hospital — no one wanted to fund poor women’s care — Mosse attended the world premiere of Handel’s Messiah in Dublin in 1742 and was inspired. He turned the future hospital site into a pleasure garden with orchestras, dances, and theater to attract wealthy donors. He was later imprisoned for debt, escaped through a castle window in Wales, hid in the mountains for three weeks, and died exhausted and broke in 1759, less than two years after the new hospital opened. Sara E. Hampson, one of Florence Nightingale’s original nurses, became the hospital’s first female superintendent in 1891 — a thread that ties Nurses Week directly to this building, Danny almost walked past.

Welcome to 2026 Nurses Week, May 6th through 12th. I’m very proud to be a nurse. I’ve been a nurse for 50 years. And my grandson’s going to nursing school next year. He’s graduating as a senior and will attend Loyola University in Chicago for its nursing program. I’m very proud. I want to tell you a story about one of the most significant things that happened during our trip to Ireland a couple of weeks ago. We were staying in the north-central city of Dublin, Ireland. Across the street, I saw a big white institutional facade with no signage. It looked like the side of the building. Next to it, on its right, was a dome with a more modern sign that read “Ambassador”. So, I went into the hotel and asked, “So what’s this building?” And they didn’t know. I looked it up, and it turned out to be the Rotunda Hospital. The Rotunda Hospital is the oldest freestanding maternity hospital in the world. Midwifery Was Scandalous. He Did It Anyway. Now let me see. I’ve got some notes here. The hospital was founded in 1745 by a man named Bartholomew Mosse, M-O-S-S-E. He was a certified surgeon. His wife and child died in childbirth. After this tragedy, he left Ireland to serve as a doctor with the British Army. While he was away, he received midwifery training at a hospital in Paris and obtained his midwifery license, which was unusual. In fact, fellows of the Royal College of Physicians were even penalized if they practiced midwifery. But Mosse wanted to change that. So, he built this small place, 10 beds, that… Let’s see, when did it open? I guess it opened in 1745. Mosse’s ambition was to build a dedicated maternity hospital in Dublin to provide medical care and shelter to the city's penniless mothers. This came after he encountered unspeakable conditions during his practice, particularly in the aftermath of the 1739 famine. So he established this 10-bed hospital. It was in a small theater called the New Booth Theatre. It says here that it was the first lying-in hospital of its kind in the world. It had only 10 beds, but in its first year, 190 babies were born, and just one mother died. But obviously, they couldn’t meet demand with 10 beds. When No One Funds Poor Mothers, Try Dancing Mosse tried to raise money to build a larger hospital, but nobody really wanted to give money to poor women. So he happened to attend the world premiere of Handel’s Messiah on April 13, 1742. While he was there, he was inspired to raise money by entertaining the wealthy. Somebody sent me a picture of the Handel statue that’s in front of the theater where the premiere was, which I thought would be interesting. According to my research, on the evening of April 13th, 1742, Handel conducted the world premiere of his Messiah on Dublin’s Fishamble Street, and Mosse was present. Historians suggest that this moment crystallized Mosse’s idea of using high-society entertainment to fund a hospital for the poor. So Mosse turned the proposed hospital site into a pleasure garden with a live orchestra, theatrical performances, and dances in a coffee house, marrying philanthropy with frivolity to reach the wealthy. Debt, Daring Escape, Death Here’s a little interesting tidbit. Lotteries nearly destroyed Dr. Mosse. Before he was able to return to Ireland, he was arrested and charged with being 200 pounds in debt, and he’s thought to have been imprisoned in Beaumaris Castle in Anglesey, Wales. The story was that he managed to escape through a window and hid in the Welsh mountains for three weeks before reaching Ireland. He then vindicated himself by publishing his receipts and lottery accounts, whatever. But less than a year after the hospital opened, he was taken seriously ill, exhausted, heavily in debt, and petrified about the prospect of arrest and imprisonment. He died on February 16th, 1759. Fix the Air, Save the Babies. Then and Now. Around 1781, when the hospital was poorly ventilated and every sixth child died within nine days of birth, they realized the problem was poor ventilation. Ventilation was improved, and mortality dropped to 1 in 20 over the following five years. They’re also planning to celebrate their millionth birth in 2026. It’s just amazing. I met a saleswoman in a sweater store who asked where we went in Dublin. When I told her about the Rotunda Hospital, she said she had a difficult pregnancy and birth without insurance. She received care at the Rotunda Hospital, with her baby in neonatal intensive care for three weeks and herself as an inpatient for two weeks. Awesome care! So, when we were there, I, an old white guy in a wheelchair, motored into the Rotunda Hospital and stopped at the registration desk to ask if I could speak with someone. I had not made an appointment. I was leaving the next day. Very nice people. I tried to get hold of people in their library, research, and marketing, but they were busy, of course. Oldest? It's Relative. I’m really impressed by the idea of being the world's longest-operating specialist hospital. I was trying to get some perspective on that, so I looked up the oldest continuously operating hospitals, and here’s what I learned. I learned that in the United States, the oldest continuously operating hospital is Bellevue Hospital in New York City, which opened in 1736 as a six-bed infirmary.[1] So, it began as a haven for the indigent and is still a major public hospital on the East Side of Manhattan. It opened nine years before Mosse opened his first lying-in hospital. The other long-running hospital is the Pennsylvania Hospital in Philadelphia[2], established in 1751 by Benjamin Franklin and Dr. Thomas Bond. It’s still operational as part of the University of Pennsylvania Health System. The oldest hospital is the Hôtel-Dieu in Paris[3], which officially opened in 650 AD, and that’s the hospital where Mosse became a midwife. There’s St. Bartholomew’s Hospital in London, founded in 1123[4]. And there’s the Hospital de Jesús Nazareno in Mexico City, opened in 1524. But really, the Rotunda is the oldest maternity-only specialist hospital, continuously operating in the world, which is a more specific and arguably more impressive claim than the general acute care hospitals Bellevue and Hôtel-Dieu, which have both moved buildings, changed missions, and been rebuilt. The Rotunda has been delivering babies in the same building since December 8th, 1757. That’s really something. Reflection: Nightingale Was Here Too So, let’s bring this back to Nurses Day and to Florence Nightingale. Interestingly, Sara E. Hampson was one of the original Nightingale nurses and the first lady superintendent of the Rotunda Hospital in 1891. So yay, nursing. Yay, history. I’m really looking forward to exploring more of this amazing hospital in Dublin. I wonder who was in charge all these years, and how it survived past Mosse and through those first decade or first few years? And then, how did the Rotunda Hospital survive war, famine, pandemics, and technological change? What research occurred there? Is there a diaspora of Rotunda alumni? Anyway, more to come. Thanks.

In this high-yield, no-fluff episode, Dennis is joined by Dr. Michael Falk, a pediatric emergency medicine physician, former academic, and combat-experienced relief worker who has run airways in Haiti post-earthquake, Mosul during the ISIS fight, Ukraine, and Gaza. They break down exactly why pediatric airways are a completely different beast in prolonged field care and give you field-proven tactics that actually work when you're the only one there with a BVM and a prayer.Key Takeaways You Can Use TomorrowPositioning is everything: One to two inches under the shoulders (or whole body) prevents automatic obstruction from the massive occiput.Adjuncts > early tube: NPA or OPA + side-lying (gravity is your friend) can keep you from tubing in the field.Tube sizing rule: Child's pinky ≈ ET tube diameter. Depth = 3× tube size. Always go smaller — you can ventilate, you can't un-damage a ripped airway.Intubation mindset: Kid airway is more anterior and cephalad. Slow down, work your way in, or you'll be in the esophagus.GCS decision:

At FDIC International 2026, our panel of EMS providers and critical‑care physicians break down ventilation during cardiac arrest: what the science supports, where practice still fails, and practical fixes you can use tomorrow. We cover why bag‑valve‑mask ventilation is a high‑risk skill (and best performed as a two‑person procedure), how over‑ and under‑ventilation change intrathoracic pressure and cardiac output, and why properly opening the airway and achieving a seal are fundamental. We discuss supraglottic airways, intubation pitfalls, CPAP and high‑flow strategies, the pros and cons of mechanical ventilators in the field, and the role of objective feedback devices. The panel emphasizes regular, low‑cost simulation training, equipment readiness, pit‑crew coordination, and the hard truth: patients die from poor ventilation more often than from the absence of intubation.

We are joined by Ian Pritchett of Greencore Homes to talk about his science-based approach to green building and the work that has led him from developing green building materials becoming the co-founder of a vertically-integrated developer and house builder.There's a lot of history and legacy to cover because Ian has been in the green building game for decades and it's this that has informed the approach being taken right now.Greencore is also challenging the Passive House Institute about the accuracy of its PHPP (passive house planning package) modelling software because their homes outperform the model's predictions because of their use of phase-change materials.Be warned, this is nerd business—Jeff gets to interrogate the build up specification—but it doesn't get too technical to be able to follow the thread.Notes from the showThe Greencore Homes website Ian Pritchett on LinkedIn A PH+ article about Neil May**SOME SELF-PROMOTING CALLS TO ACTION**We don't actually earn anything from this podcast, and it's quite a lot of work, so we have to promote the day jobs.Follow us on the Zero Ambitions LinkedIn page (we still don't have a proper website)Jeff and Dan about Zero Ambitions Partners (the consultancy) for help with positioning and communications strategy, customer/user research and engagement strategy, carbon calculations and EPDs – we're up to all sortsSubscribe and advertise with Passive House Plus (UK edition here too)Check Lloyd Alter's Substack: Carbon UpfrontJoin ACANJoin the AECB Join the IGBCCheck out Her Retrofit Space, the renovation and retrofit platform for women**END OF SELF-PROMOTING CALLS TO ACTION**   

On this week's episode, Cyrus and Nick host a spirited discussion with Drs. Rory Spiegel and Max Hockstein where we debate the merits of Airway Pressure Release Ventilation (APRV). What's the rationale for this? When is it appropriate? IS it appropriate… or is it witchcraft? Is it physiologically foolish or a perfectly logical option for hypoxemic respiratory failure? Good for all comer, good for a subset or does it belong with the vials of succinylcholine and DL blades? We may not have all the answers but on this episode we do our best to explore this ventilator mode and help you decide whether the juice is worth the squeeze! Check us out and let us know YOUR feelings while leaving us a review! Hosted on Acast. See acast.com/privacy for more information.

Quotes from the episode: "If you're building something new, it has to be better in almost every way or it won't catch on."   "The stuff that's bad inside your home doesn't filter out, you have to move it out."   "We stopped over-modeling and just started testing in the real world as fast as possible."    This episode of the Building HVAC Science Podcast features Austin Riesenberger, founder of Swerv Air, a young entrepreneur tackling a surprisingly overlooked problem: how to bring fresh air into homes without sacrificing comfort, energy efficiency, or simplicity. Drawing from his background in HVAC engineering, physics, and personal struggles with asthma and poor indoor air quality, Austin set out to rethink ventilation from first principles. Swerv's solution is a compact, window-mounted fresh air system that filters incoming air while recovering heat and moisture through a regenerative cycling core. Unlike traditional ERVs that are bulky and contractor-installed, this unit is designed for easy, consumer-level installation with strong performance. The conversation dives into the technical trade-offs, including airflow, efficiency, noise, and form factor, as well as the importance of real-world testing over theoretical modeling in product development. Beyond the product itself, the episode highlights Austin's startup journey. From rapid prototyping and supply chain challenges to early beta deployments across multiple climates, the discussion offers insight into how modern hardware companies iterate quickly and build demand. It wraps with a call for beta testers and collaborators, positioning Swerv as a potential bridge between consumer IAQ needs and traditional HVAC solutions.     Austin's LinkedIn:https://www.linkedin.com/in/austin-riesenberger-73502a1b6/   Swerv website: https://swervair.com/   Beta Tester SignUp: https://swervair.com/#beta   This episode was recorded in April 2026.

Send us Fan MailDr. Gabriel Altit and Daniela Villegas from the NeoCardioLab at Montreal join Ben and Rupa to reflect on a packed PAS filled with hemodynamics science — from pulmonary hypertension phenotyping to heart-brain interactions in the golden hour. Dr. Altit makes the case that just as neonatology learned to embrace gentle ventilation, it is time to think about gentle hemodynamics — intervening thoughtfully, recognizing different clinical phenotypes, and knowing when to remove interventions before they carry a price. He also previews early 3D echo data suggesting that a single clip at day 7 to 10 of life may already carry a signature predicting which babies will develop adverse cardiopulmonary outcomes by 36 weeks. Daniela shares her approach to family consent and research recruitment — sitting down, leaving papers behind, connecting families to the history of research that made current NICU care possible, and always giving them space to process before returning for an answer.Support the showAs always, feel free to send us questions, comments, or suggestions to our email: nicupodcast@gmail.com.

Send us Fan MailDr. Nathan Sundgren, neonatologist and NRP educator at Texas Children's Hospital, joins Ben to discuss one of the most deceptively difficult skills in neonatal resuscitation — effective bag mask ventilation. He shares findings from a fellowship training study showing that respiratory function monitor feedback improves ventilation technique equally well across all three device types, and tackles the harder question of why that same technology has yet to show clinical benefit in the delivery room — pointing to human factors, cognitive overload, and the need for a dedicated respiratory coach role rather than a better device alone. He also reflects on the evolution of team leadership in neonatal resuscitation, why doing a procedure and leading a team simultaneously is impossible, and where people can find his free educational content on YouTube at Texan Neo-Ed.Support the showAs always, feel free to send us questions, comments, or suggestions to our email: nicupodcast@gmail.com.

Pool Pros text questions hereIn this continuation of their conversation, Lee, Shane, and Nick are joined again by industry expert Spiros from Next Gen Experts to break down a topic that's generating serious noise across the pool industry right now: proposed workplace exposure changes and what they actually mean.This isn't a surface-level chlorine conversation. It's a deep dive into how regulations, standards, and real-world operations collide—and where the industry needs to be paying attention versus where it might be overreacting.

What happens when the battlefield drops 30 feet underground into a collapsed building, ancient tunnel system, or booby-trapped basement? You don't just “clear” it — you assess it like a critical trauma patient while everything tries to kill you.In this raw, no-fluff episode, Dennis sits down with Sean McKay — 20+ year veteran of dynamic high-threat rescue, nonlinear physics guy, and the man who turns “impossible” subterranean ops into repeatable TTPs. Fresh off 48 hours with zero sleep (and still caffeinated to the gills), Sean drops a masterclass on why underground environments are exponentially more dangerous than anything on the surface.From atmospheric sucker punches (O₂ depletion, CO₂ buildup, toxic off-gassing) to structural collapses, comms blackouts, mental exhaustion, and the brutal reality of casualty extraction in spaces tighter than a coffin, this episode is packed with battlefield-proven principles you won't find in any manual.If you run rescue, work in SOF, or just want to understand what happens when the fight goes subterranean — this is required listening. Key Takeaways1. Treat the subterranean environment like a patient — use the exact same rapid/ongoing assessment template medics already know by heart. 2. Atmospheric threats (O₂ depletion, CO₂, displacement gases) are silent killers; monitor early and often. 3. Speed is security, but only after deliberate recon — one small “worm” goes first, the team enlarges behind him. 4. Improvise like your life depends on it: rubble, wood studs, high-lift jacks, and building debris become your cribbing and shoring. 5. Plan for mental exhaustion — 45 minutes underground feels like 8 hours; isolation and darkness will mess with your head. 6. Always identify safe havens and load-bearing walls as you move; never trust foreign engineering. 7. Casualty extraction multiplies complexity exponentially — every medical intervention costs time and movement. 8. Worst-case heuristics save lives: assume the worst, then back out from there. 9. Geology and soil type tell you whether a collapsed structure is worth occupying or a death trap. 10. Best practices are written in blood — create your own on the spot using context and innovation.Chapters- 03:10 – Why Subterranean Is the Ultimate Nonlinear Nightmare - 05:29 – Real-World Examples: Afghanistan Karez, Tunnels, Collapses - 07:25 – Atmospheric & Environmental Pathology (The Silent Killers) - 09:09 – Structural Collapse, Shoring & Improvised Solutions - 11:41 – Scenario: Occupying a Collapsed Multi-Story Basement - 13:36 – Patient-Assessment Template for the Environment - 15:31 – Tunnel Rat Recon Tactics & Atmospheric Monitoring - 17:56 – Sustainment, Mental Exhaustion & Comms Hell - 20:22 – Heuristics, Worst-Case Planning & Spidey Sense - 23:16 – Real Heuristic Examples from the Field - 26:11 – Destabilization, Cribbing & Load-Bearing Principles - 27:19 – Fire Chief Mindset – Maintaining Global Awareness - 29:45 – Safe Havens, Injuries & Team Support - 30:56 – Gases, Ventilation & Natural Airflow Hacks - 35:12 – Fans, Vertical Ventilation & Building Features - 38:52 – When to Walk Away – Red Flags & Geology Clues - 41:31 – Water, Electrical & Urban Subterranean Hazards - 44:48 – Casualty Extraction in Confined Spaces - 48:39 – Creating Best Practices on the Fly For more content, go to ⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠www.prolongedfieldcare.org⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠Consider supporting us: ⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠patreon.com/ProlongedFieldCareCollective⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠ or ⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠www.lobocoffeeco.com/product-page/prolonged-field-care⁠⁠

Matt Risinger sits down with Bill Graber and Steve Rogers of The Energy Conservatory to explore how diagnostic testing informs high-performance construction. The conversation centers on blower door testing, pressure mapping, and airflow measurement as tools to verify airtightness and identify leakage pathways. They discuss how builders and energy raters use data to refine building enclosures, improve indoor air quality, and coordinate HVAC system performance. The group also touches on evolving codes, training, and the growing expectation for measurable results in residential construction.  Huge thanks to our podcast episode Huber Engineered Woods.  Learn more at: https://www.huberwood.com Watch full episodes of Matt on Facebook, Instagram and Build Show Network. https://www.facebook.com/buildshownetworkhttps://www.instagram.com/risingerbuild/https://buildshownetwork.com/go/mattrisinger Don't miss a single episode of Build Show content.

We take a look at the state of the green building sector through the lens of itss biggest dedicated show in the UK, Futurebuild. It on 12–14 May this year and you can sign up here.Helping us to peek behind the curtain is the event's director, Martin Hurn, a man who is, ultimately, responsible for it all.It seemed with a conversation because this year Futurebuild was acquired by a new owner and repackaged to become a super event. The green building great big networking event has merged with UK Construction Week and the Stone and Surfaces Show. In light of this we get into the history of Futurebuild that sheds a little light on how the impact of changes that it's going through right now are a little more like a return to its roots.The episode has a bit of a long wind up because we've included a chunk of preamble in which Jeff explains his background to Martin which wasn't intended for the episode but it ended up revealing similarities, and differences, in their backgrounds that felt worth including. Both Martin and Jeff have been in this working within the business of the built environment for about the same amount of time (early 00s), and both coming from publishing backgrounds. They've seen the heydays, boom times, and catastrophes created by the Celtic Tiger and the UK's solar subsidisation and feed-in tariffs. Consequently, the pair of them are able to offer a some illuminating and interesting perspectives on where they see the sector at this strange point in time.We also let Martin plug the show.And, at the end we do get around to asking ‘how sustainable are events?'Notes from the showRegister with Futurebuild 2026 for your event passThe Futurebuild website Martin Hurn on LinkedIn **SOME SELF-PROMOTING CALLS TO ACTION**We don't actually earn anything from this podcast, and it's quite a lot of work, so we have to promote the day jobs.Follow us on the Zero Ambitions LinkedIn page (we still don't have a proper website)Jeff and Dan about Zero Ambitions Partners (the consultancy) for help with positioning and communications strategy, customer/user research and engagement strategy, carbon calculations and EPDs – we're up to all sortsSubscribe and advertise with Passive House Plus (UK edition here too)Check Lloyd Alter's Substack: Carbon UpfrontJoin ACANJoin the AECB Join the IGBCCheck out Her Retrofit Space, the renovation and retrofit platform for women**END OF SELF-PROMOTING CALLS TO ACTION**   

What is social value? It's a messy, ill-defined beast that's increasingly a core component of public procurement, and it's something that we worked on recently so it's been front of our minds.We invited Michael McLaughlin (LHC Procurement Group) onto the show to talk through what he thinks about social value, and what he thinks it could be if the sector was able to organise itself better. No shade intended and we're not suggesting that it's easy to fix things, but we have looked into it. While there's a lot of great work being done there are an unconscionable number of opportunities being wasted, and not for want of trying.Notes from the showMichael McLaughlin on LinkedInThe LHC Procurement Group website LHC on LinkedIn **SOME SELF-PROMOTING CALLS TO ACTION**We don't actually earn anything from this podcast, and it's quite a lot of work, so we have to promote the day jobs.Follow us on the Zero Ambitions LinkedIn page (we still don't have a proper website)Jeff and Dan about Zero Ambitions Partners (the consultancy) for help with positioning and communications strategy, customer/user research and engagement strategy, carbon calculations and EPDs – we're up to all sortsSubscribe and advertise with Passive House Plus (UK edition here too)Check Lloyd Alter's Substack: Carbon UpfrontJoin ACANJoin the AECB Join the IGBCCheck out Her Retrofit Space, the renovation and retrofit platform for women**END OF SELF-PROMOTING CALLS TO ACTION**

In this episode of the HVAC Know It All Podcast, host Gary McCreadie talks with Christopher Rystedt, Technical Sales and Trainer at Airzone Control, about air distribution and zoning with VRF and inverter systems. In Part 2, they discuss common applications such as hotels and residential homes, and how zoning can work with multiple brands and system types. Christopher explains how modern zoning avoids bypass dampers by adjusting fan speed and system capacity based on demand. They also cover ventilation modes, zone weighting, and how airflow is balanced across different spaces. The conversation wraps up with setup tips, training options, and how zoning can help manage refrigerant limits and reduce system size and cost. Gary and Christopher discuss how modern HVAC zoning systems work with VRF and inverter equipment in both commercial and residential applications. They explain how systems can control multiple zones or units from one platform, even across different brands. Christopher describes how proper duct design and variable fan speed help avoid the need for bypass dampers while maintaining correct airflow. They also cover ventilation settings, including local and system-wide fan operation, and how zone weighting helps balance airflow based on duct size. They finish by talking about system setup, training resources, and how zoning can help reduce refrigerant use and overall system costs.   Expect to Learn: How HVAC zoning systems can control multiple rooms using VRF and inverter equipment. How one platform can manage different brands and types of HVAC units together. Why proper duct design and variable fan speed help eliminate the need for bypass dampers. How ventilation modes work at both the zone level and system level to move air.

In this EM Cases update on cardiac arrest management, Dr. Sheldon Cheskes and Dr. Rob Simard join Anton to walk us through the evolving science and bedside practicalities of cardiac arrest management in the wake of the 2025 ACLS Guidelines. They answer questions such as: What are the most common failures in CPR quality, and how can we recognize and correct them in real time? Should we employ head up CPR, and if so how? How should we interpret ETCO₂ during cardiac arrest, and why shouldn't we chase a single number? How can we minimize peri-shock pauses and optimize defibrillation success at the bedside? Is the traditional two-minute CPR cycle too rigid, and should we be shocking earlier in cases of refibrillation? What is the evidence behind dual sequential external defibrillation (DSED), and when should we use it? After 3 shocks or earlier? How does hyperventilation during cardiac arrest harm patients, and what strategies can reliably prevent it? What is compression-adjusted ventilation (CAV), and how can it improve ventilation consistency during resuscitation? What is the optimal dose of epinephrine in patient with Ventricular Fibrillation? and many more... Please donate to EM Cases to ensure ongoing Free Open Access Medical Education here: https://emergencymedicinecases.com/donation/ This is a deep dive into the critical inflection points in resuscitation where small changes in technique and decision-making may have the greatest impact on outcomes.

We're back for another great episode of Keepin It Rio. This week, our buddy Aron DeLong with Lomanco stops by to chat about a topic that doesn't get enough love. Yep, Attic Ventilation. From years in Distribution to becoming the new guy in a niche industry, Aron has stepped up and become a Leader in Ventilation. We talk about the importance of proper balance for efficiency and energy savings, as well as uncovering some really bad things that can happen if you don't understand how to properly vent a home. Plentiful amounts of value in this one.Send us Fan MailSupport the show

Lucy Lyons of Kestrix joins us this week to talk about their use of drones, infrared imaging, and AI to quicken the pace of retrofit surveying. Specifically, with regard to a case study detailing their work with Peabody housing association.Kestrix is a software company that works with landlords to assess their building stock in terms of which homes need help and whether the retrofit works that have been carried out are performing. They use their sophisticated broad-brush surveys and image analysis is is designed to help asset owners get the greatest value out of stretched budgets and capacity, investing time wisely and proving value for money.Notes from the showLucy Lyons on LinkedInKestrix on LinkedIn The Kestrix website The Kestrix & Peabody case study that we refer toNational Audit Office report of retrofit performance: Energy efficiency installations under ECONHMF award 'Best Warm Home Initiative' 2026New Study Suggests Using AI Made Doctors Less Skilled at Spotting Cancer**SOME SELF-PROMOTING CALLS TO ACTION**We don't actually earn anything from this podcast, and it's quite a lot of work, so we have to promote the day jobs.Follow us on the Zero Ambitions LinkedIn page (we still don't have a proper website)Jeff and Dan about Zero Ambitions Partners (the consultancy) for help with positioning and communications strategy, customer/user research and engagement strategy, carbon calculations and EPDs – we're up to all sortsSubscribe and advertise with Passive House Plus (UK edition here too)Check Lloyd Alter's Substack: Carbon UpfrontJoin ACANJoin the AECB Join the IGBCCheck out Her Retrofit Space, the renovation and retrofit platform for women**END OF SELF-PROMOTING CALLS TO ACTION**

JEMS Development Editor Mike Brown sits down with Jonathan Epstein, who leads the American Red Cross healthcare product management team, to unpack the Red Cross's new Resuscitation Suite. Jonathan explains how the suite reimagines BLS, ALS and pediatric/neonatal resuscitation with EMS-first blended learning, a “practice as you perform” approach that embeds local protocols and integrated cognitive aids, including a digital app with step-by-step algorithms and clinical decision support. They discuss adaptive learning and computer-adaptive testing that shrink classroom time, an upcoming VR pathway that delivers team-based practice and certification, and realistic expectations for AI, dual sequential defibrillation and mechanical CPR. Ventilation, measurement and device design are highlighted as targets for education and engineering solutions.

ITRC's Vapor Intrusion Mitigation training is a series of eight (8) modules, presented over two sessions. If you took the ITRC VIM series previously, the content has stayed the same, but the new course directs people to the Vapor Intrusion (VI) Toolkit resources published in January 2026 by ITRC. The Vapor Intrusion Mitigation training series provides an overview of VIM and presents information from the 2026 ITRC VI Toolkit (which includes fact sheets, technology information sheets, and checklists). Session 1:Introduction & Overview of Vapor Intrusion Mitigation Training TeamConceptual Site Models for Vapor Intrusion MitigationCommunity Engagement During Vapor Intrusion MitigationRapid Response & Ventilation for Vapor Intrusion MitigationRemediation & Institutional Controls Session 2:Active Mitigation ApproachesPassive Mitigation ApproachesSystem Verification, OM&M, Curtailment and Shutdown When certain contaminants or hazardous substances are released into the soil or groundwater, they may volatilize into soil vapor. VI occurs when these vapors migrate up into overlying buildings and contaminate indoor air. The ITRC VI Toolkit combines the previous ITRC VI-related guidance documents (VI 2007, PVI 2014, VIM-1 2020), along with updates, into one comprehensive resource toolkit (including fact sheets, technology information sheets and checklists) published in January 2026. After the Vapor Intrusion Mitigation series, you should understand:How to locate and utilize the relevant document, fact sheets, technology information sheets, and checklistsThe importance of a VI mitigation conceptual site modelHow community engagement for VI mitigation differs from other environmental mattersWhen to implement rapid response for VI and applicable methodologies The differences between remediation, mitigation, and institutional controlsAvailable technologies for active and passive mitigation, and design considerations for various approachesHow/when/why different mitigation technologies are appropriateHow to verify mitigation system success, address underperformance, and develop a plan for curtailment of a mitigation system and shutdown We encourage you to use the ITRC VI Toolkit and these training modules to learn about VI mitigation and how you can apply these best practices to improve decision-making at your sites. For regulators and other government agency staff, this understanding of VI mitigation can be incorporated into your own programs. While the training makes every effort to keep the information accessible to a wide audience, it is assumed that the participants will have some basic technical understanding of chemistry, environmental sciences, and risk assessment. As with other emerging contaminants, our understanding of VI mitigation continues to advance. This training provides the participants with information on areas where the science is evolving and where uncertainty persists.

Baz Iyer (Vulcan) and Stephen Lloyd (Savills Earth) join us to talk about the likely impact of the UK's long-awaited Future Homes Standard (FHS) and, perhaps more importantly, the Home Energy Model (HEM).HEM is the new model that will inform the UK's Energy Performance Certification (EPC) rating system. It's much more detailed in terms of the information that it demands about the buildings it is being used to rate, and therefore much more demanding of the assessors.But this means that it can be much more useful for modelling the energy performance of buildings because it will better reflect how the building will be experienced by its users.  It won't be perfect but the level of detail that it demands means that homeowners may be able to use EPCs to make meaningful decisions about how to improve the buildings in which they live. This also means that, in time, it is conceivable that HEM can become a design tool in the same way designers use PHPP to predict performance and calibrate design. That's certainly what Baz is planning and why he and Stephen have been interrogating the place HEM will occupy in the UK construction sector, the impact it might have on its culture, and the opportunity that its adoption will open up.If anyone needs some help getting to grips with this I'd recommend they connect with Baz, he's very friendly and well-informed.Notes from the showBaz Iyer on LinkedInStephen Lloyd on LinkedIn The Vulcan websiteThe Savills Earth websiteVulcan on LinkedInOld ZAP #1 - 'Incompetence still reigns supreme' in energy ratings: DPE certification, EPCs, BERs, and a little bit of ESGOld ZAP #2 - ZAP Shady business #1 – overheating, and Camden: we should think about solar gain all year round, with Zoe De Grussa (BBSA)**SOME SELF-PROMOTING CALLS TO ACTION**We don't actually earn anything from this podcast, and it's quite a lot of work, so we have to promote the day jobs.Follow us on the Zero Ambitions LinkedIn page (we still don't have a proper website)Jeff and Dan about Zero Ambitions Partners (the consultancy) for help with positioning and communications strategy, customer/user research and engagement strategy, carbon calculations and EPDs – we're up to all sortsSubscribe and advertise with Passive House Plus (UK edition here too)Check Lloyd Alter's Substack: Carbon UpfrontJoin ACANJoin the AECB Join the IGBCCheck out Her Retrofit Space, the renovation and retrofit platform for women**END OF SELF-PROMOTING CALLS TO ACTION**

At the heart of the modern world lie ventilation shafts. We may not notice them, but wherever there are tunnels, sewers, mines, car parks and energy stations under our feet, vents will be doing vital work keeping them cool and fume-free. Vents come in a wonderful and inventive variety of forms. Adventurous Vents: A Journey through the Ventilation Shafts of Britain (Penguin, 2025) by Lucy Lavers, Judy Ovens, Suzanna Prizeman celebrates them both in their own right as intriguing individual structures, and as an innovative way to tell the story of Britain's subterranean industrial development from the eighteenth century to the present day. Here are one hundred of the most interesting ventilation shafts, dotted around Britain, sometimes in the most surprising places. You'll find them masquerading as sculptures and small buildings, adorned with fine details or displaying their purpose with confidence. Whether you're inspired to take off in search of them, or just to admire them from your armchair, vents are fabulous objects. By putting them – perhaps for the very first time – centre-stage, Adventurous Vents celebrates a highly unusual but exciting architectural form. This interview was conducted by Dr. Miranda Melcher whose book focuses on post-conflict military integration, understanding treaty negotiation and implementation in civil war contexts, with qualitative analysis of the Angolan and Mozambican civil wars.

Cost: Free for NYU Learners $250 for Non-NYU Learners Click Here to Register and Begin Module 1 I. Phase 1: Stabilization (Minutes 0–10) The “Rearrest” Window & Pathophysiology High-Risk Period: Rearrest rates reach 30% within the first minutes post-ROSC. Shock Incidence: Two-thirds of patients develop profound hypotension/shock as initial resuscitative efforts subside. Catecholamine Washout: Super-physiologic “code-dose” epinephrine (1mg IV) typically wears off within ~3 minutes post-ROSC, leading to predictable hemodynamic collapse. Secondary Injuries: Evaluate for “CPR-induced trauma” (blunt thoracic trauma, rib fractures, pneumothorax, liver/splenic lacerations). Immediate Resuscitative Actions Vascular Access: Transition rapidly from IO to reliable IV access within 1–2 minutes. Prioritize Intraosseous (IO) placement within 5 minutes if IV attempts fail; intra-arrest data suggests no significant difference in early outcomes. Vasoactive “Bridge”: Maintain a “bolus-dose” pressor at the bedside for immediate push-dose titration. Options: Phenylephrine, dilute Epinephrine, or dilute Norepinephrine (titrated to effect rather than rigid dosing). Physician-Specific Task: Arterial Line: Goal: Placement within 5 minutes of ROSC. Preferred Site: Femoral (by landmarks/blind if necessary) for speed; should be a 80 mmHg. The BOX Trial Nuance: While the BOX trial showed no difference between MAP 63 vs. 77, its cohort (Denmark) had exceptionally high survival rates (70% back to work) and short response times, which may not generalize to North American populations with lower shockable rhythm incidence. Permissive Hypertension: If the patient is “self-driving” to higher pressures, do not aggressively lower them, as this may be a physiologic demand for cerebral blood flow. Ventilation and Oxygenation PaCO2 Management: Target: High-normal to slightly hypercarbic (45–55 mmHg). Rationale: Avoid accidental hyperventilation (PaCO2

If you work with commercial HVAC systems, you touch VAV boxes every day. But are they working with your air handler or quietly fighting it? In episode 535 of the Smart Buildings Academy Podcast, you step back from sequences and setpoints to look at VAV box control theory as a complete system. Because a VAV box is not just a damper and a reheat coil. It is a decision-making device balancing comfort, ventilation, and energy while the air handler tries to keep the entire building stable. When airflow, static pressure, supply air temperature, and ventilation minimums are not coordinated, you feel it in callbacks, energy bills, and unhappy occupants. This episode challenges you to think beyond individual points and start thinking system-wide. Topics Covered How VAV boxes and air handlers must coordinate to maintain stability Static pressure control and why reset strategies change everything Supply air temperature reset and its impact on airflow and reheat Ventilation minimums, occupancy, and indoor air quality control Reheat coordination and preventing simultaneous heating and cooling If you design, program, or troubleshoot VAV systems, this conversation will change how you approach your next project.

In this episode of the Society of Critical Care Medicine (SCCM) Podcast, host Maureen Madden, DNP, RN, CPNP-AC, CCRN, FCCM, speaks with Javier Varela, MD, MSc, about his study, “Acute Bronchiolitis in Infants on Invasive Mechanical Ventilation: Physiology Study of Airway Closure,” published in the September 2025 issue of Pediatric Critical Care Medicine. The study revealed new insights into airway pathophysiology in infants with severe bronchiolitis who require mechanical ventilation, a population that comprises a substantial portion of winter pediatric intensive care unit (PICU) admissions worldwide. Dr. Varela is an intensivist in the PICU in the Department of Pediatrics at Clínica Alemana de Santiago, in Santiago, Chile. Differing ventilatory strategies and the heterogeneous phenotypes of bronchiolitis motivated Dr. Varela's team to investigate airway closure, which was detected in seven of the 12 patients included in the study. Airway opening pressure frequently exceeded the set positive end-expiratory pressure (PEEP) levels—highlighting a potential gap in traditional ventilator management. Dr. Varela explains that respiratory mechanics, particularly driving pressure and respiratory system compliance, can be misinterpreted when airway opening pressure is not considered. Study limitations included bacterial coinfection in nearly half the patients and the constraints of a single-center design, but Dr. Varela said that these factors did not appear to alter the physiologic observations. Although more research is needed before making clinical recommendations, the study established a foundational understanding of airway closure in patients with bronchiolitis and underscores the need for future work on personalized ventilation strategies, PEEP titration, and the potential heterogeneity of airway behavior in this population.

c02 The Silent Killers in Your Home | Episode 586 Good morning. It's 45 degrees, I'm dragging butt, and today we're talking about something that quietly kills a lot of people every year. Carbon dioxide. Smoke. Ventilation. The invisible stuff. This isn't sexy prepping. This is boring, basic, “why are we even talking about this?” prepping. Because a $20 device can literally save your life. Carbon Dioxide: The Cheap Life Insurance You're Ignoring I was scrolling headlines this morning and saw another story about deaths from carbon dioxide poisoning. It happens every single year. A lot. And here's the stupid part — a CO₂ detector costs like twenty bucks. Even if you don't run a propane heater, even if you think your house is “fine,” they're cheap enough that not owning one is just negligence. Modern homes are airtight. That's great for energy efficiency. It's not great if something is off-gassing inside. We run: A Mr. Buddy propane backup heater On-demand propane hot water Both can introduce CO₂ into the air. Under normal conditions? Fine. Crank the flame too high? It absolutely spikes. We've set ours off before. We've seen it climb toward 150 parts per million. The alarm goes off, we crack windows, levels drop. If we didn't have the monitor? We'd have no clue. That's the scary part. Without a detector, you literally do not know. Backup Heat Means Backup Monitoring If you're running any kind of propane heater — especially in winter — this is not optional. Yes, some heaters have built-in shutoff sensors. The Mr. Buddy claims it will shut itself off if CO₂ gets too high. Cool. I still want my own monitor. That's a belt-and-suspenders situation. Redundancy matters when the failure mode is “you don't wake up.” Also: crack a window. It feels counterintuitive when you're trying to heat a space, but fresh air matters. Smoke Detectors: The Highest ROI Device in Your House If your house doesn't have smoke detectors, I don't know what to tell you. They are cheap. The return on investment is astronomical. The ROI of not dying in a house fire? I'll take that trade every day of the week. Yes, I've had one fail before. I installed one when I built my house, it broke, and there was a stretch where we didn't have one. It happens. Then you fix it. Also: change your batteries. Do not be the person whose smoke detector chirps for three months. Just replace the batteries. Batteries: The Boring Prep That Matters CO₂ detectors. Smoke alarms. Flashlights. They all need batteries. Stock some. I bought one of those zippered foam battery organizers that holds multiple sizes. It's nerdy, but having a full case of ready-to-go batteries is awesome. Also, don't cheap out on garbage rechargeable batteries. I bought some that were labeled rechargeable and either weren't — or were just trash. They wouldn't hold a charge. When it comes to life-safety gear? Buy decent batteries. Combination Units vs Dedicated Monitors Many modern smoke detectors also monitor CO₂. That's fine. Two-for-one is great. Personally, I like a dedicated CO₂ monitor that shows parts per million in real time. I want to see the numbers. I want to watch them drop when I open a window. But if you're starting from scratch? A combo unit is far better than nothing. The goal is awareness. Radon and Other Invisible Problems Carbon dioxide isn't the only invisible threat. Radon is real. I've watched a YouTube renovation series where a homeowner tested high radon levels in a basement before sealing and fixing it. That's something you may want to test, depending on where you live. Ventilation matters. Fresh air matters. And if you have natural gas? Know where your emergency shutoff is. That's non-negotiable. Final Thoughts This episode isn't dramatic. It's not about collapse.

🧭 REBEL Rundown 📌 Key Points The 4 Steps of an ED Consult:👋 Introduce yourself and your role🎯 Lead with the outcome (the ask)🧾 Give a focused case summary (why it’s theirs + what you’ve done)🔁 Close the loop (timeline, next steps, contingencies) Click here for Direct Download of the Podcast. 📝 Introduction Today we’re tackling one of the most important (and most under-taught) skills in emergency medicine: how to call a consult in the ED and what to do when a consultant pushes back.To call a consult in the ED, start with a brief introduction, lead with the outcome you need (“the ask”), give a focused decision-relevant summary, and close the loop with timeline and next steps. If the consultant resists, clarify the “why,” restate the ask, offer alternatives, and escalate when patient safety or disposition is at risk.After two decades in emergency medicine and countless consult calls, here’s a simple framework—plus copy/paste scripts—to make your consults faster, clearer, and easier to say “yes” to. 🤔 Why Consult Skills Matter in Emergency Medicine Consults aren’t a formality—they’re a patient-care intervention. Strong consult communication:Reduces delays in time-sensitive careImproves ED throughput and dispositionDecreases conflict and miscommunicationClarifies ownership and next stepsProtects the patient (and the team) when plans are unclear 🪜 The 4-Step ED Consult Framework (Introduction → Ask → Summary → Close the Loop) Most consult friction comes from one of two problems: unclear expectations or excessive noise. This four-step structure solves both.1) Introduce yourself and your roleA simple intro sets a professional tone and removes ambiguity.Script: “Hey, this is Swami, one of the ED attendings. I’m calling for an ortho consult.” 2) Lead with the outcome (the ask)Don’t bury the lede. The consultant wants to know what you need—immediately.Script: “I’m calling about a patient with a suspected septic knee. I need you to evaluate for operative management.” 3) Give a focused, decision-relevant summaryYour summary should answer:Why this is your service’s problemWhat’s already been doneWhat I’m worried about / what decision is needed nowScript: “43-year-old man with no major PMH, 3 days of knee pain and swelling. XR negative. Febrile. Aspiration yielded purulent fluid—cultures sent. We started antibiotics after the tap. He’s hemodynamically stable.” High-yield pearl: Add quick “stability anchors” when relevant:“Airway stable, pain controlled.”“Neurovascularly intact.”“No signs of compartment syndrome.”“No hypotension or escalating oxygen requirement.” 4) Close the loop (timeline + next steps)This prevents the consult from floating in limbo and protects patient flow.Script: “When do you expect to see the patient, and do you want anything done before you arrive—NPO, repeat labs, additional imaging?” 📝 ED Consult Script General ED Consult Script “Hi, this is Dr. ___ in the ED. I’m calling for a ___ consult. The reason is ___. Briefly: ___ year-old with ___. We’ve done ___ and started ___. I’m concerned about ___. Can you see them today, and what’s your preferred next step?” Septic joint / Ortho Example “Hi, this is Swami in the ED. I need an ortho consult for suspected septic arthritis. 43-year-old with 3 days of atraumatic knee swelling and fever. XR negative. Tap produced purulent fluid—cultures sent. Antibiotics started after aspiration. Can you evaluate for operative management, and when can you see the patient?” Neurology example (time-sensitive) “Hi, this is Dr. ___ in the ED. I need neurology for suspected acute stroke. Last known well ___. NIHSS ___. CT/CTA completed (or pending). I’m calling to discuss candidacy for thrombolysis/thrombectomy and next steps. When can you evaluate and what additional workup do you want now?” ⛓️‍💥 Common ED Consult Mistakes (and Fixes) Mistake: Long story before the askFix: Lead with the outcome in the first sentenceMistake: Unfiltered data dumpFix: Provide only decision-relevant detailsMistake: No timelineFix: Ask explicitly when they’ll see the patient and what they need firstMistake: Implicit “ownership”Fix: Clarify who is admitting, who is following, and what happens if the patient worsens ✋ What to Do When a Consultant Pushes Back Even a perfect consult can meet resistance. Your job is to stay calm, keep it professional, and protect the patient.1) Ask “why?”Don’t argue first—diagnose the refusal.Script: “Help me understand your concern about seeing this patient.” Many refusals are based on misunderstanding: wrong service, missing key detail, or incorrect assumption about stability.2) Restate the consult in one sentence, then offer optionsIf the conversation starts spiraling, reset it.Script: “To be clear, I’m concerned this is septic arthritis and needs ortho evaluation. If you don’t feel you’re the right service, who should be—rheum, medicine, or another surgical team?” This keeps you collaborative while preventing dead ends.3) Humanize the decision (use sparingly)This is a “high-voltage” tool. Use it when stakes are high and you’ve already clarified the medical facts.Script: “I’m worried we’re missing something time-sensitive. If this were your family member, what would you want us to do next?” Use it to re-anchor to patient risk—not as a guilt tactic. ⚡️When and How to Escalate a Consult Escalation isn’t personal—it’s a safety mechanism when there’s an impasse that threatens timely care.When to escalateTime-sensitive condition is delayed (e.g., septic joint, cord compression, testicular torsion, GI bleed with instability)No clear disposition plan despite reasonable ED evaluationConsultant refusal blocks needed specialty decision-makingPatient safety or deterioration risk is increasing in the ED How to escalate (lowest to highest intensity)Ask for the consultant’s attending (if speaking to a resident)Call the on-call attending directlyInvolve ED leadership/medical directorEscalate to service chief/department chair (rare, but real)Hospital supervisor/admin escalation for immediate operational impasseScript: “We’re at an impasse and the patient needs a decision. I’m escalating to clarify ownership and ensure timely care.” ️ Documentation Tips for Consult Refusals Documentation should be factual and patient-centered, not punitive.Include:Your clinical concern and why the consult is neededWho you spoke with (name/role)Their stated reason for refusal or delayAlternatives discussedEscalation steps taken and final plan 👉 FAQ: Emergency Medicine Consults What is the best way to call a consult in the ED?Introduce yourself, lead with the specific ask, summarize only decision-relevant details, and close the loop with a clear plan and timeline.What should I say when a consultant refuses to see a patient?Ask why, clarify misunderstandings, restate your concern and the ask, and request an alternative plan or appropriate service.When should I escalate a consult?Escalate when an impasse delays time-sensitive care, threatens patient safety, or prevents appropriate disposition.How do I document a refused consult?Document the clinical concern, who you spoke with, their stated reason, alternatives discussed, and escalation steps taken. 🏁 Conclusion Mastering emergency medicine consults makes you faster, safer, and easier to work with. The goal isn’t to “win” a consult call—it’s to get the patient the right care, with clear ownership and a shared plan.

Ready to turn your home into a haven of fresh air? Join me, Eric G, and my buddy John Dudley as we dive into the world of ventilation with our good friend Ken Nelson from Panasonic Eco Systems. We're tackling the big stuff—like why proper ventilation is the unsung hero of home comfort and health. Spoiler alert: it's not just about avoiding that funky bathroom smell; we're talking about keeping your indoor air quality top-notch and preventing that delightful mold garden from sprouting in your garage. So, if you're ready to breathe easier and maybe learn a thing or two about how to keep your air (and your home) feeling fresh, then stay tuned! If you've ever walked into your garage and thought, 'Wow, it feels like a swamp in here,' then boy, do Eric G. and John Dudley have a treat for you! In this lively episode, they sit down with Ken Nelson from Panasonic Eco Systems to tackle the often-overlooked topic of ventilation. Spoiler alert: it's not just about avoiding that horrid bathroom fog! Ken dives deep into the world of Energy Recovery Ventilators (ERVs) and how they can transform your indoor air quality from ‘yikes' to ‘ahh.' We learn that moisture isn't just a bathroom problem; it lurks in your kitchen and garage too, ready to wreak havoc on your precious belongings. Ken humorously shares his personal experiences with Panasonic products, emphasizing their longevity and efficiency. The trio explores the absurdities of building codes and how they often miss the mark on practical ventilation solutions. Plus, they discuss the importance of maintaining those fancy gadgets to keep your home breathing easy. So, grab a drink, kick back, and get ready to rethink your home's air flow!Takeaways:Ventilation is not just about the bathroom; it's crucial for kitchens and garages too, so stop ignoring those moisture issues, folks!Panasonic's ERVs can reject up to 90% of moisture, meaning if it's 80% humidity outside, you could be breathing in a cool 55% inside. No more sweaty living!Mechanical ventilation is key because relying on open windows is like hoping for a miracle every time the wind blows—let's be real, it rarely works like that.The right ventilation system can save you big bucks on energy costs, so invest wisely instead of going for the cheapest options that just gather dust.Don't skimp on filter changes in your ERV; that filter is your home's first line of defense against the nasty outdoor air, and ignoring it is just asking for trouble.If your ventilation is only as good as your building code allows, you're basically living in a barely legal house—time to step it up!Companies mentioned in this episode:Panasonic VentilationPanasonic EcosystemsThanks for listening to Around the house if you want to hear more please subscribe so you get notified of the latest episode as it posts at https://around-the-house-with-e.captivate.fm/listenIf you want to join the Around the House Insider for access to the back catalog, Exclusive Content and a direct email to Eric G and access to the show early https://around-the-house-with-e.captivate.fm/support...

🧭 REBEL Rundown 🗝️ Key Points 💨 NIV = Support without a tube: CPAP, BiPAP, and HFNC improve oxygenation and reduce the work of breathing.🫁 CPAP = Continuous pressure: Best for hypoxemic patients (e.g., pulmonary edema, OSA).️ BiPAP = Two pressures (IPAP/EPAP): Great for hypercapnic failure (e.g., COPD, obesity hypoventilation).🌬️ HFNC = Heated, humidified high flow: Reduces effort, improves comfort, and enhances oxygen delivery.🩺 Supportive, not definitive: NIV stabilizes patients while the underlying cause is treated. Click here for Direct Download of the Podcast. 📝 Introduction Non-invasive ventilation (NIV) refers to respiratory support provided without endotracheal intubation. The most common modalities include continuous positive airway pressure (CPAP), bilevel positive airway pressure (BiPAP), and high-flow nasal cannula (HFNC). These therapies aim to improve oxygenation, reduce the work of breathing, and potentially prevent invasive mechanical ventilation. 💨 CPAP and BiPAP CPAP delivers a single, continuous pressure during inspiration and expiration. This pressure (commonly 5–10 cm H₂O) helps recruit atelectatic alveoli, reduce shunt, and improve oxygenation. It is commonly used for conditions like pulmonary edema, obstructive sleep apnea, or mild hypoxemia without significant ventilatory failure.BiPAP alternates between two pressures:Inspiratory positive airway pressure (IPAP), augments tidal volume and unloads inspiratory muscles.Expiratory positive airway pressure (EPAP), maintains alveolar recruitment and improves oxygenation.The differential between IPAP and EPAP is critical for reducing hypercapnia in patients with COPD exacerbations or acute hypercapnic respiratory failure.IndicationsCPAP: hypoxemia without major ventilatory failure (e.g., cardiogenic pulmonary edema, atelectasis, OSA).BiPAP: hypercapnia with increased work of breathing (e.g., COPD exacerbation, neuromuscular weakness, obesity hypoventilation).A helpful way to conceptualize CPAP and BiPAP is through the hairdryer analogy. Imagine placing a hairdryer in your mouth: 🩺 Clinical Considerations Masks can be uncomfortable, impair secretion clearance, and limit oral intake.Some patients require sedation to tolerate NIV, but this carries risks in patients with unprotected airways.NIV is thus a high-stakes intervention requiring close monitoring.Common starting dose to understand titration, but start at the level appropriate for your patient:  IPAP 10 cm H₂O / EPAP 5 cm H₂O (“10/5”) and are titrated:Increase IPAP to improve tidal volume and CO₂ clearance.Increase EPAP to recruit alveoli and improve oxygenation.Both may be raised simultaneously if the patient is both hypoxemic and hypercapnic. 🚀 High-Flow Nasal Cannula (HFNC) H: Heated & humidified – improves mucociliary clearance, prevents airway drying, and enhances tolerance. I: Inspiratory flow – high flow meets or exceeds patient demand, reducing respiratory rate and effort.F: Functional residual capacity – modest generation of positive end-expiratory pressure (PEEP), promoting alveolar recruitment.L: Lighter – generally more comfortable and less restrictive than mask-based NIV.O: Oxygen dilution – minimizes entrainment of room air, delivering higher and more predictable FiO₂.W: Washout – flushes anatomical dead space, reducing CO₂ rebreathing.HFNC delivers heated, humidified oxygen at high flow rates (30–60 L/min) through wide-bore nasal prongs. A mnemonic, H-I-F-L-O-W, helps summarize its mechanisms:Indications: Traditionally used for acute hypoxemic respiratory failure (e.g., pneumonia), HFNC is increasingly studied for hypercapnic failure as well, with trials suggesting non-inferiority to BiPAP in select populations.

A recent study reveals that bedroom ventilation plays an essential role in sleep quality. Carbon dioxide (CO₂) levels need to remain below 1,000 ppm, ideally under 800 ppm, for deeper, uninterrupted sleep Opening windows can help with airflow, but it's not always ideal due to outdoor pollutants, noise, or security risks. In such cases, a ventilation system is a safer and more reliable option Air purifiers filter indoor air but do not introduce fresh air. To maintain optimal air quality, pair filtration systems with proper ventilation rather than relying on one system alone Monitoring CO₂ levels in your bedroom helps ensure proper air exchange. Using a reliable CO₂ meter provides insight into ventilation efficiency and allows adjustments to improve sleep quality To further improve indoor air quality, regularly clean or replace air filters, minimize the use of synthetic air fresheners, scented candles, and harsh cleaning chemicals, opt for natural, nontoxic alternatives, and air out your home safely
