Question

Quizplus · Accepted Answer

Hypoxemia, a condition characterized by low levels of oxygen in the blood, can be caused by various factors including diffusion impairment (where gas exchange across the alveolar-capillary membrane is compromised), alveolar hypoventilation (insufficient ventilation to oxygenate the blood), $\dot { V } / \dot { Q }$ mismatch (an imbalance between ventilation and perfusion), and intrapulmonary shunting (blood bypasses the lungs without gas exchange). All these mechanisms can lead to reduced oxygen levels in the arterial blood.
