Hypoxia & Hypoxemia
exp date isn't null, but text field is
Abstract
Understanding Hypoxemia (low oxygen in the blood) & hypoxia (low oxygen in the tissues) is a fundamental part of critical care. This OnePager reviews all the key concepts (oxygen content & delivery, Aa gradient) and explains all FIVE causes of hypoxemia (low inspired O2, alveolar hypoventilation, V/Q mismatch, right to left shunt, and diffusion limitation) plus a bonus SIXTH cause which is often overlooked (low mixed venous O2).
