Quizplus · Accepted Answer

Acute respiratory distress syndrome (ARDS) is characterized by a decrease in compliance, pulmonary infiltrates, respiratory distress, and refractory hypoxemia. The pulmonary shunt fraction is increased in ARDS, which means that deoxygenated blood is circulating to the arterial system without passing through ventilated alveoli. Option A is incorrect because functional residual capacity is reduced in ARDS due to alveolar collapse. Option B is also incorrect because compliance is decreased in ARDS. Option C is incorrect because instead of hyperinflated terminal air sacs, ARDS is characterized by collapsed or consolidated alveoli.
