Oxygen Content And Oxygen Delivery - Concepts and Equations Explained Clearly

Oxygen content and oxygen delivery are two concepts that are critical to understand how the body functions and what happens when that function breaks down. In this video we explain these processes in a clear and full manner with clinical examples included. 📚 MINI COURSES, STUDY GUIDES, PRACTICE QUESTIONS, AD FREE VIDEOS, EDUCATIONAL DISCUSSIONS in our WBM Emergency Critical Care Patreon Community - Join Today!!   / whiteboardmedicine   Aerobic metabolism goes through the Kreb's Cycle and ends in Oxidative Phosphorylation, which creates the bulk of the body's energy in the form of ATP. Oxygen is critical to this pathway and without it cells are forced to primarily utilize anaerobic metabolism creating lactate and very few ATP. This is why oxygen content and oxygen delivery are so critical to understand. Oxygen content is the amount of oxygen contained in the arteries. There are two general components of this being the oxygen attached to the hemoglobin molecules in the red blood cells and the amount of oxygen dissolved in the arteries. As such, the equation for oxygen content includes hemoglobin, oxygen saturation of the hemoglobin, and the partial pressure of arterial oxygen using two constants to convert the units to milliliters of oxygen per deciliter of blood. We dive into this equation and explain it in a way that makes sense, including examples using normal numbers, anemia, hypoxemia, and hyperoxia. Oxygen delivery is the amount of oxygen delivered through the blood stream to the tissues. This is based on the cardiac output and the oxygen content with cardiac output being a result of stroke volume and heart rate. We again decipher this equation in a way that makes sense using the concepts behind it. We provide examples of the calculation. Lastly, we go through different parts of oxygen content and delivery that can go awry clinically and how to best intervene. 👉 Now find WhiteBoard Medicine on all major Podcast platforms (Apple, Spotify, Amazon, More)!
