Podcasts about Gas exchange

In this episode of the Critical Oxygen podcast, I am joined again by Coach Michelle Simmons where we discuss the importance of breathing and how it affects physiology and performance. Michelle shares her personal experience of using breathwork to manage anxiety and improve athletic performance. We emphasize the significance of diaphragmatic breathing and its impact on posture, mindset, and oxygen delivery. The conversation also touches on the limitations of breathing incorrectly and the benefits of practicing breath control during high-intensity efforts. We highlight the need for athletes to be aware of their breathing and its potential to optimize performance. I share my personal experience of switching from mouth breathing to nose breathing during low intensity training. While there is limited scientific research on the topic, we speculate that nose breathing may stimulate the vagus nerve and activate the parasympathetic nervous system, leading to a more relaxed state and better performance. They also discuss the adaptability of the pulmonary system and the need for further research in this area. More about Michelle in her words: Personally: I did my first triathlon in 1995! Fell in love with it immediately. I continued to race for ~25 years. I rarely race anymore but I still train bc I enjoy it and want to be healthy and fit enough to train with my athletes at times. In my time, I did 18x Ironmans, including 4x in Kona. Professionally: I started coaching a few friends in 2008. I took every opportunity to learn (still do!) and my coaching business grew to the point where I've been doing it full time for the last 15 years. I am the founder and Head Coach at TeamBSC Triathlon. I work with amateurs of all ages and abilities- some beginners and others who ultimately qualify for the World Champs! I'm actively involved in supporting endurance sports on Oahu. I coach Kailua Masters Swim team, lead a local monthly Girls Ride, and am a board member for Aloha State Bike Racing Association. Sometimes I present educational workshops for local athletes. TAKEAWAYS 1) Breathing plays a crucial role in physiology and performance, and conscious control of breath can help optimize performance. 2) Diaphragmatic breathing, which involves expanding the rib cage and breathing low and slow, can improve posture, mindset, and oxygen delivery. 3) Practicing breath control during high-intensity efforts can help athletes stay calm, focused, and optimize oxygen utilization.

Sulfur containing AA generate H2SO4. Only 50-100 mEq of acid produced from these sources. - Cleared by the kidneys - Law of Mass Action - Velocity of reaction proportional to the product of the concentrations of the reactants - Goes through mass action formula for water - Concludes that water has H of 155 nanoM/L, more than the 40 in plasma - Says you can do the same mass experiment for every acid in the body - Can do it also for bases but he is not going to. - Acids and Bases can be strong or weak - Strong acids completely dissociate - Weak acids not so much - H2PO4 is only 80% dissociated - Weak acids are the principle buffers in the body - Then he goes through how H is measured in the blood and it becomes clear why pH is a logical way to measure. - Then there is a lot of math - HH equation - Derives it - Then uses it to look at phos. Very interesting application - Buffers - Goes tot he phosphate well again. Amazing math describing how powerful buffers can be - Big picture the closer the pKa is to the starting pH the better buffer, i.e. it can absorb lots of OH or H without appreciably changing pH - HCO3 CO2 system - H2CO3 to H + HCO3 has a PKA of 2.72 but then lots of Math and the bicarb buffer system has a pKa of 6.1 - But the real power of the bicarb buffer is that it is not a sealed system. The ability to ventilate and keep CO2 constant increases the buffering efficiency by 11 fold and the ability to lower the CO2 below normal increases 18 fold. - Isohydric principle - There is only one hydrogen ion concentration and since that is a critical part of the buffer equation, all buffer eq are linked and you can understand all of them by understanding one of them. So we just can look at bicarb and understand the totality of acid base. - Bicarb is the most important buffer because - High concentration in plasma - Ability for CO2 to ventilate - Other buffers include - Bone - Bone is more than just inorganic reaction - Live bone releases more calcium in response to an acid load than dead bone - More effect with metabolic acidosis than respiratory acidosis - Hgb - Phosphate - Protein

Q1: What was the purpose behind setting up IGX and how exactly did it happen? Ans: >Started working on Indian Energy Exchange (IEX) in 2007 >Introduced IT-enablement of the trading system in energy sector >Trading system in power sector was not transparent before the IEX was set up >Natural gas sector enjoys many marketers and importers of liquefied natural gas (LNG) >The sector also lacked transparency, ease of doing business before the gas exchange (IGX) was established >IGX platform was inaugurated in June 2020 by former minister of Petroleum & Natural Gas Dharmendra Pradhan     Q2: How do you see the progress made by IGX since inception? What kind of growth do you see in liquidity and do they meet expectations? Ans: >Witnessed impressive growth in volume during last financial year >Volume tripled every quarter during the period >Sellers that are usually PSU giants prefer to use the platform because of assurance of payment and fast payment cycle >IGX started with 12/13 participating members. Today it has 26 members Q3: What is the reaction of the smaller consumers? Does it meet their requirements or address their concern after the IGX was set up? Ans: >Exchange aims to facilitate small consumers get the best price >Increased prices of gas during the last financial year made viability of small consumers limited >Demand from large consumers that continue to buy gas at elevated rates are driving the volume growth >As price of gas comes down, smaller consumers will join in     Q4: Govt now seems to be allowing domestic gas producers in the exchange. What kind of new projects or plans you have for IGX once the domestic gas reaches the market? Ans: >Domestic gas will give comfort to a lot of small buyers >When domestic gas producers come on board the exchange they will need different delivery points >Out of the five hubs in the country, four are LNG terminals >Domestic gas producers generally sell near KG Basin >Few domestic producers are also located in West Bengal and Jharkhand >IGX applied to Petroleum and Natural Gas Regulatory Board (PNGRB) for approval of more domestic delivery points   Q5: India is a budding gas economy and wants to increase the share of gas in the overall mix from 6% to 15% by 2030. What will be the impact of high gas and LNG prices the country's plans and on IGX? Ans: >High prices of gas and LNG will have impact on demand > Prices would have been stable if there was no geopolitical crisis >High prices of gas also impacted the govt's vision for increasing consumption from 6% to 15% >IGX has not been impacted as much because it got compensated by high volume of consumption by bigger players     Q6: It is clear now that Europe wants to reduce its reliance on Russian gas and have the target of 2026-2030, which coincides with India's target. They can afford to outbid emerging markets. And then we have China that is ready to pay higher prices, as we saw last year. What can India do? Or, what role can IGX play in this? Are options limited? Ans: >For India, choices are limited because everything impacts the price and we are sensitive to price >Europe and China will dominate the market because they have the ability to pay higher than emerging markets >City Gas Distribution (CGD) and fertilizer will continue to grow

In this episode, I discuss how gas exchange occurs and important laws that enable gas exchange. The two main concepts are diffusion limited gas exchange and perfusion-limited Gas exchange. In diffusion limited exchange, pressure gradient is maintained-.i.e it’s always present. In perfusion-limited gas exchange, pressure gradient is not maintained. Equilibration is reached. --- Support this podcast: https://anchor.fm/kamesa-anota/support

When we breathe, air first circulates to the bronchi, followed by the bronchioles and terminal bronchioles, which opens up at the end to create an alveolar duct from which air sacs derive. Each lung has over 300 million alveoli, which gives a total surface area of 70 meters squared. https://www.respiratorycarestore.com

The latest Issue Round Up looks at how climate change will affect switchgrass, the environmental impacts of planting this grass on a large scale, as well as management techniques for bioenergy crop growth and the reduction of environmental impacts.

Plants leaves are sealed with a gas-tight wax layer to prevent water loss. Plants breathe through microscopic pores called stomata (Greek for mouths) on the surfaces of leaves. Over 40% of the carbon dioxide, CO2, in the atmosphere passes through stomata each year, as well a water volume twice that of the whole atmosphere. As the key conduits for CO2 uptake and water evaporation, stomata are critical for both our climate and plant productivity. Thus, not surprisingly, the total number and distribution of stomata are strictly regulated by plants to optimize photosynthesis while minimizing water loss. The mechanisms for such regulation have remained elusive.
