This course gives you a practical, physiology-grounded approach to recognizing and managing pulmonary shunt in the anesthetized patient. You’ll differentiate anatomical vs physiological shunt, connect shunt fraction to real-world hypoxemia that “won’t fix” with FiO₂ alone, and learn how to use recruitment maneuvers, PEEP, positioning, and lung-protective ventilation to restore gas exchange. Designed for anesthesia providers, it focuses on translating shunt concepts into concrete intraoperative and critical care strategies that improve oxygenation and respiratory outcomes.
