WebThe main causes of hypoxemia are alveolar hypoventilation, ventilation-perfusion (V/Q) mismatching, and intrapulmonary shunting. Intrapulmonary shunting occurs when blood passes through a portion of a lung that is not ventilated. Physiologic shunting is normal and not a cause of hypoxemia. WebA ventilation/perfusion (V/Q ratio) mismatch occurs when: a disruption in blood flow inhibits the exchange of oxygen and carbon dioxide in the lungs, even though the alveoli are …
