Hypoxemia vs Hypoxia
Hypoxemia - Partial pressure of arterial oxygen (PaO2) is below normal
Hypoxia - Insufficient oxygen
hypoxia - Increased O2 ... unable to use O2 ... O2 delivery to tissues
Low O2 saturation that does not respond to supplemental O2
- Key diagnostic feature (sat < 85%
Low O2 saturation ... to supplemental O2 ... a falsely low O2 ... true decrease in O2 ... impairment of O2
Causes of Generalized Hypoxia - Differential Diagnosis
 • Hypoxemic - Not enough O2 (Most Common)
 •
Hypoxemic - Not enough O2 ... Cells can't use O2
