Hypoxemia vs Hypoxia Hypoxemia - Partial pressure of arterial oxygen (PaO2) is below normal Hypoxia - Insufficient oxygen supply at the tissue level Hypoxemia without hypoxia - Increased O2 delivery to compensate for low PaO2 Hypoxia without hypoxemia - Tissues are unable to use O2 effectively. O2 delivery to tissues is impaired Jane Lock @kcolenaj #hypoxia #hypoxemia #differential #diagnosis #comparison #pulmonary
