- pathophysiology of hypoxia and hypoxemia
- using Aa gradient to determine reason for hypoxemia
- Hypoxemia is decreased saturation, which is directly affected by (alveolar gas equation calculates oxygen content of alveoli).
Oxygen content of alveoli is dependent on oxygen content of inspired air and mixing of gas exchange.
- : inspired air O2 content
- : alveolar O2 content is lower because of gas exchange
- : arterial blood content is lower because of shunt
- : oxygen saturation is directly dependent on arterial oxygen content. Oxygen saturation is percentage of hemoglobin site that's bound with oxygen molecule.
