In this episode of the Flex Diet Podcast, I sit down with Dr. Nathan Jenkins to discuss how to improve performance, body composition, and long-term health through the lens of aerobic development and metabolic flexibility. Nathan shares his journey from exercise physiology and coaching CrossFit athletes to his new role teaching physiology at the University of Georgia School of Medicine. We discuss why metabolic flexibility is such a powerful framework for understanding everything from biochemistry and exercise performance to metabolic disease. We also dive into interpreting maximal exercise testing data, including VO₂ measurements, EKG analysis, and near-infrared spectroscopy (NIRS), along with how different energy systems work together during training and competition. Nathan explains why building an aerobic base is critical for repeated high-intensity performance, how pacing impacts outcomes, and why the ability to "suffer" is actually a trainable skill. To wrap up, we cover practical strategies you can apply right away, including prioritizing protein and carbohydrates, improving sleep quality, and addressing common micronutrient deficiencies through blood work, such as magnesium, vitamin D, and omega-3 status.

In today's episode, we will pick up where we left off last week during my "podcast" presentation of The Mitochondrial Triad lecture I gave last month in Rome. Undoubtedly, you are getting more nuggets of wisdom in this podcast version, as I am able to go down various rabbit holes and dig deeper into the details since there are no time constraints. For example, today's episode that is entirely on the topic of methylene blue is longer in duration than my entire presentation at the symposium in Rome. Last week, I covered the first two topics of my talk: mitochondria (i.e., why they are important for health and why mitochondrial dysfunction is the bane of wellness and healthspan) and red light therapy. This week, again, we will cover the topic of methylene blue (MB) in great depth; including the history of MB, the mechanisms of MB, the health benefits and correlative research on MB, and considerations surrounding MB for those deliberating the potential use of MB for their health and wellness goals. With that being said, make sure your brain is full of flowing electrons and buckle up for an information-packed episode!

Clinical Anaesthesia Podcasts: Conversations with Keith and Courtney
In the last of the 3 episodes on oxygen, Keith and Courtney discuss how we can monitor the concentration of oxygen our patient is receiving and also how to monitor our patient's oxygenation levels – both manually and with a machine. We can “flip the lip” (but human eyesight can't detect cyanosis for quite some time), use our pulse oximeter or run a blood gas analysis. Assuming the patient has normal haemoglobin levels. Anaemia, carbon monoxide poisoning from a house fire and even an overdose of certain everyday drugs can affect functional haemoglobin availability! They finish this episode highlighting the importance of using an oxygen concentrator in a circle breathing system, and why we initially have high fresh gas flows to remove the nitrogen sitting in the tubing and carbon dioxide absorbing canister.
Clinical Anaesthesia Podcasts: Conversations with Keith and Courtney
Welcome to the first episode in our third season of the Conversations with Keith and Courtney podcast. This season looks into Oxygen and Carbon Dioxide – from the moment oxygen leaves the cylinder until it gets to the mitochondria, and then how the waste product (carbon dioxide) gets from the tissue to the lungs so it can be exhaled. In this episode, Keith and Courtney discuss methods we use to provide oxygen therapy to our patients before anaesthesia, such as through pre-oxygenation via flow-by or face mask delivery, and what type of oxygen concentration you're actually reaching! If it leaves the cylinder at 100%, it certainly doesn't mean that the patient gets that. And they will leave you with some frightening figures in regards to using insufficient fresh gas flows in an oxygen cage... Much of what is discussed in this episode is also in our article “Are you providing effective Oxygen Therapy?” which you can check out here: https://bit.ly/3mNoQrw
Lukas Furtenbach, a major mountaineering expedition guide company and is now a top supplier of supplemental oxygen systems to all teams climbing Everest. He partnered with Neil Greenwood of Summit Oxygen to create Everest Oxygen focusing on supplying supplemental oxygen to the mountaineering industry. His Austrian-based Furtenbach Adventures offer global climbs, including most of the 8000-meter mountains, the Seven Summits, the Volcanic Seven Summits, and Ski Mountaineering. However, they have made a name for themselves with their "Flash Expeditions," which takes only three weeks to climb Everest, compared to the classic style, which takes six to eight weeks. One of his secrets is using an altitude tent, aka a hypoxia chamber, that acclimatizes his clients to 7,00 meters (23,000 feet) at home. This reduces the number of rotations required before the summit push and reduces the overall time spent at base camp. It's not really a secret as anyone can rent or buy a tent, and other companies like Alpenglow out of Lake Tahoe, California, also specialize in rapid expeditions. However, Furtenback's team out of Innsabruk closely monitors their client's progress over the eight weeks they sleep in the tent, making daily changes to optimize the process. Lukas is also investing in advanced technology to remotely monitor his customer's health while climbing and evolving the oxygen regulator, the brains of the system that manages flow rates, to allow for an unprecedented eight liters per minute (lpm) flow. He only uses this high flow rate for short sections, for example, on the Hillary Step, to allow the climber to move faster. Otherwise, they run at today's traditional two, four and six lpm rate. In this Podcast, we explore the evolution of using supplemental oxygen, Lukas's approach and several other Everest topics. We cover: 2:24 - The Chinese closure of Everest for the past four years, and will they open in Autumn for 8000ers? 4:45 - Will COVID be a factor for Everest 2023? 5:55 - Furtenbach Adventures Carbon Neutral approach to mountaineering 10:02 - Climbing Everest in three weeks vs. six to eight weeks 11:35 - Pre-acclimatizing at home using altitude tents 22:13 - The history of altitude tents (In France in the late 1970s) 25:52 - Is using supplemental oxygen cheating? 29:54 - Everest Oxygen supplies systems to other teams 30:04 - Understanding the Oxygen Delivery System 47:22 - Types of Delivery Systems 52:14 - Remote Monitoring of a Climber's Health 56:17 - Everest 2023 Predictions They will update their social media, Facebook, Twitter, and Instagram, throughout the expedition.

Welcome to PICU Doc On Call, a podcast dedicated to current and aspiring intensivists. My name is Pradip Kamat My name is Rahul Damania, a current 2nd year pediatric critical care fellow. We come to you from Emory University,School of Medicine, Children's Healthcare of Atlanta, Atlanta, GA. Today's episode is dedicated to O2 delivery in the PICU. We would like to highlight in this episode Stanford University School of Medicine Pediatric Critical Care's LearnPICU website. Thehttp://learnpicu.com ( LearnPICU.com) website Is dedicated to reviewing clinical topics related to pediatric critical care, and is an open access resources which Is widely accessed worldwide. The website has over 10,000 visits each month, and is managed by Dr. Kevin Kuo - Clinical associate professor of pediatrics pediatric critical care at Stanford University. Dr. Kuo has Been featured on our prior episode entitled seven habits of highly effective Picu fellows, and we are very excited to collaborate with his educational resources to provide you the listener a comprehensive educational experience. Rahul, let's go ahead and get into today's case. A 17-year old boy is admitted after he was struck by a car at slow speed while crossing the street. He is has SPO2 of 98%, HR 98 bpm with a normal capillary refill and perfusion. His blood gas at admission to the PICU reveals a ph of 7.3/PCO2 35/PaO2 196 mm Hg on 50% NRB with 100% O2 flowing at 12LPM. His admission hgb is 10.5 gm%. 4 hours post admission, the nurses noticed that the patient is tachycardic to 150s, with a drop in his BP, delayed capillary refill, with cool extremities and increased output from the chest tube. His SpO2 has decreased to 86% and PaO2 on his blood gas is now 65mm HG. He is found to have a POC Hgb of 6.8 mg/dL. Let's take this case and highlight key components of O2 delivery and O2 consumption. Lets focus on O2 delivery first. Rahul What are the components of O2 delivery ? Pradip, O2 delivery is made of O2 content X Cardiac output Simply put, O2 content is the amount of blood present in 100ml of arterial or venous blood. Its is denoted by CaO2 or CvO2 and its unit is mL O2 / dL blood or mL O2 per 100 mL of blood. Before we introduce the complicated formula, let's just appreciate the variables within the equation. Oxygen content is going to be a function of three variables: This is going to be Hgb, Saturations on the hemoglobin also known as SaO2, and the amount of oxygen that is dissolved within the blood also known as your PaO2. Pradip, Can you elucidate further about O2 content? O2 content is given by the formula: CaO2 = (1.34X Hgb gm/dl X SaO2) + (0.003X PaO2) Important points to remember about above formula is that the constant 1.34 (or 1.36 as given by some textbooks) is the amount of O2 in mL bound by one gm of Hgb and is called as the O2 carrying capacity of Hgb. In a healthy person say with 15gm% of Hgb, the O2 carrying capacity is about 15X1.34 = 20gm%. Now many times amount of O2 bound to Hgb may not always reflect 100% saturation So we need to factor the % oxygen saturation into the oxygen carrying capacity of the Hgb. The final element is to understand that some oxygen is dissolved in the plasma and is calculated using a constant 0.003 X PaO2. Typically 100ml of arterial blood with a saturation of 100 will contain 100 X 0.003 = 0.30ml of dissolved oxygen. Rahul can you calculate the pre-decompensation oxygen content in the above case? The above patients hgb pre-decompensation = 10.5gm%. His room air saturation 98% and his PaO2 is 196. CaO2 = (1.34X10.5X0.98) + 0.003 X 196 = 13.7 + 0.58 = 14.2ml O2/dL blood. Great - what is the post decompensation CaO2.? The post decompensation CaO2 can be estimated using same formula as above: CaO2 = (1.34 X 6.8 X0.86) + (0.003 X 65) = 7.8 + 0.195 = 7.9 O2/dL blood. Exactly So if you see the pre and post bleed O2 content just with a drop in Hgb from 10.5 to 7.5gm/dL: There is almost a 38% decrease in...

High and Low Oxygen delivery systems
Host Brad Kearns welcomes Primal Health Coach Ryan Baxter to the show to discuss the importance of intentional breathing as it relates to minimizing workout (and life) stress and optimizing fat burning. Ryan discusses the important role breathing plays in whether we burn carbs or fat during aerobic workouts. Beyond the need to observe the “180 minus age” in heartbeats per minute, the efficiency of our delivery of oxygen to working muscles is also relevant. Ryan explains how improving our CO2 tolerance can improve oxygen delivery, making workouts less stressful and improving performance. The less CO2 you can tolerate the quicker you are going to want to exhale it from your body—that’s why we default to shallow, panting, inefficient breaths - not only during workouts but also at rest. This stimulates sympathetic (fight or flight) nervous system function while nose breathing stimulates parasympathetic (rest and digest) nervous system function. The greater you can tolerate C02 the slower you will be able to exhale it. You’ll learn how to dabble in the popular practice of nose breathing both at rest and during workouts. Try the shiftadapt test (linked below) to see how well you tolerate CO2 now and track improvement over time. Links: Ryan's Instagram Ryan's Blog Shiftadapt Test

Concepts discussed include the oxygen delivery equation, differentiating hypoxia from hypoxemia, and a discussion of V/Q mismatch and shunts. In the follow-up episode - Acute Respiratory Failure II: Clinical Management & Oxygen Therapies - we'll apply these concepts to the management of acute respiratory failure and discuss the benefits and harms of oxygen therapy.

Episode 8 – Oxygen Delivery After Cardiac Arrest Resuscitation During cardiac arrest resuscitation, most patients are intubated and placed on 100% oxygen. In this podcast, Drs. Teran and Abella discuss recent investigations that suggest that too much oxygen may worsen post-arrest injury. Global resuscitation guidelines suggest down-titration of oxygen as tolerated to maintain adequate O2 saturation, but it’s not clear how well this is done- many patients are left on high oxygen “dose” for hours.

One of the symptoms of hypoxia is decreased judgment and decision-making ability — not good for pilots. It can sneak up on you slowly, and by the time you realize it's happening, you're too impaired to do anything about it. So pilots have a lot of different ways to ensure their brain is getting the oxygen it needs, even at high altitudes. Today I talk about hypoxia, the different types of hypoxia and its signs and symptoms, and the different ways pilots have of receiving supplemental oxygen.

This audio summary reviews a randomized controlled noninferiority trial that compared a solar-powered oxygen delivery system to standard delivery from oxygen cylinders in resources-limited settings.
Patrick McKeown is one of the world’s leading teachers of the Buteyko Breathing Method which was created in the 1950s by a Russian doctor named Dr. Konstantin Buteyko. McKeown suffered from asthma for decades until he found the Buteyko Method. At which point, he reversed his asthma symptoms and then dedicated his life to helping others optimize their breathing. In this book, he extends the Buteyko Method into an approach he calls the Oxygen Advantage. Big Ideas we cover include the #1 obstacle to optimal breathing, Oxygen Delivery 101, the #1 breathing tip, and how to dial in your sleep.

For the 30 years, clinical understanding of haemodynamic resuscitation has been based on physiological paradigms that focus on convective oxygen delivery. Most of these emphasise the role of cardiac output, haemoglobin and recommend interventions using synthetic agents such as dobutamine, synthetic colloids and blood transfusions. Markedly influenced by industry, these interventions and strategies hijacked critical thinking creating a belief in the utiliity of attaining short-term physiological surrogates for resuscitation that have little relevance in improving patient-centred outcomes. This 'physiological fallacy' has been demonstrated in high-quality RCTs of fluids, goal-directed therapy and catecholamines, that paradoxically inform the interpretation of new insights in the physiological basis of health and disease.
