In this episode we talk about this very common phenomenon in anaesthesia, the difference between ETCO2 and PaCO2.Essentially this all comes down to patient and equipment factors.BUT the essential element that makes the largest difference is DEAD SPACE.we discuss the factors effecting it, and the Bohr equation that measures dead space.Please support us on our Patreonhttps://www.patreon.com/anaesthesiaAll proceeds will go to Fund a Fellow to help train anaesthetists in developing countries whilst acknowledging the work it takes to keep creating this educational resource.If you enjoyed this content please like and subscribePlease post any comments or questions below. Check out www.anaesthesiacollective.com and sign up to the ABCs of Anaesthesia facebook group for other content.Any questions please email lahiruandstan@gmail.comDisclaimer: The information contained in this video/audio/graphic is for medical practitioner education only.

Mason dives deep into the metabolic differences between fasting and starvation, exploring hormonal responses like insulin and glucagon. The conversation shifts to local anesthetic pharmacology, detailing how lignocaine works and the benefits of combining it with adrenaline. He also tackles the complexities of shunt calculations and the effects of bronchial blocks on cardiovascular dynamics. Additionally, Mason explains MAC values and how they vary with age, offering study strategies while engaging listeners in an enlightening viva format.

Professor David Story, a leading anaesthetist and researcher from the University of Melbourne, dives deep into the complexities of acid-base physiology. He explains the importance of understanding the Stewart approach and simplifies the definitions of acids for clinical use. The conversation explores practical models for assessing acid-base disorders during surgery, including the impact of CO2 on mixed disorders. Additionally, Story highlights the clinical value of quantifying 'other ions' and introduces useful tools like the bedside Stewart app for quick assessments.

In this insightful conversation, Dr. Bob Smith, a retired anaesthetist with expertise in cardiopulmonary exercise testing, shares his remarkable journey from the 1960s UK fellowship exams to his clinical work in Australia. He discusses the evolution of anaesthesia practices, including the critical importance of understanding VO2 and anaerobic thresholds for patient outcomes. Bob also dives into exercise prehabilitation and how advances in anaesthesia have reduced postoperative mortality, all while blending his athletic background with medical insights.
