Supplemental oxygen administration is usually effective in treating hypoxemia related which situation?
A) Physiologic shunting
B) Dead space ventilation
C) Alveolar hyperventilation
D) Ventilation-perfusion mismatching

Question

Quizplus · Accepted Answer

Supplemental oxygen administration is effective in treating hypoxemia related to alveolar hypoventilation and ventilation-perfusion mismatching.When intrapulmonary shunting exists,supplemental oxygen alone is ineffective.In this situation,positive pressure is necessary to open collapsed alveoli and facilitate their participation in gas exchange.Positive pressure is delivered via invasive and noninvasive mechanical ventilation.
