Hypoxemia vs. Hypoxia
- Hypoxemia is low blood oxygen, measured by blood gas or pulse oximetry.
- Hypoxia is qualitatively low tissue oxygen, which is what truly matters clinically.
Oxygen Delivery
- Oxygen delivery depends on oxygen content (CaO2) and cardiac output.
- CaO2 is calculated using hemoglobin, saturation, and dissolved oxygen (PAO2).
Arctic Icefish
- Arctic icefish lack red blood cells and hemoglobin, relying on dissolved oxygen.
- They adapt with large hearts, cold environments, large capillaries, and low oxygen use.
