2) Interstitial edema
3) Decreased shunt
4) Narrowing of the alveolar-capillary membrane

Question

Quizplus · Accepted Answer

ARDS (Acute Respiratory Distress Syndrome) is characterized by abnormal surfactant production and interstitial edema, which contribute to the respiratory distress seen in this condition. Decreased shunt is not associated with ARDS; instead, increased shunting due to non-aerated lung tissue is a hallmark of the disease. Narrowing of the alveolar-capillary membrane is not a typical feature; rather, the membrane's permeability increases, leading to edema and impaired gas exchange.
