This episode covers CaO2, CvO2, DO2, C(a-v)O2, and tissue consumption. This includes discussion on different types of hypoxias, normal values, causes of abnormal values, and the equations involved. Practice questions are asked at the end.

This episode covers PAO2, P(A-a)O2, a/A ratio, and P/F ratio, including what affects alveolar oxygenation, A-a gradient, and clinical applications. Practice questions are included at the end.

This episode covers hyperbaric oxygen, heliox, nitric oxide, and carbogen. Indications, hazards, and complications, as well as how to deliver each gas. As always, there are practice questions at the end.

This episode covers high flow systems including air-entrainment masks, large volume air-entrainment nebulizers with aerosol mask, trach mask, face tent, and T-piece. I also talk briefly about oxygen hoods, croup tents, and high flow nasal cannulas. 

This episode talks about what it means to be low or high flow and how to ensure that a system is in fact, high flow. This includes calculating air entrainment ratios, total flow, and finding minimal flow to ensure you meet the patient's inspiratory demand. I also talk about when to use a high flow system over a low flow one.

This episode covers different types of nasal cannulas and how to estimate the FiO2. Low flow masks, including simple, non-rebreather, and partial rebreather. I talk about when to use each mask and the hazards that can potentially be associated with them. Find the Ultimate Oxygen Therapy Study Package on www.myvresp.com.
