The underlying physiological process leading to pure hypercapnic respiratory failure is which of the following?
A) Ventilation/perfusion mismatch
B) Intrapulmonary shunting
C) Diffusion impairment
D) Alveolar hypoventilation

Question

Quizplus · Accepted Answer

When a person cannot achieve adequate ventilation to maintain a normal partial pressure of carbon dioxide in the arteries (PₐCO₂),it is known as acute hypercapnic respiratory failure.Ventilation/perfusion (V/Q)mismatch,intrapulmonary shunting,and diffusion impairment lead to hypoxemic respiratory failure.
