Which of the following statements describe the pathophysiology of adult respiratory distress syndrome?

2)decreased surface tension in the alveoli
3)excessive fluid and protein interstitially and in the alveoli
4)multiple diffuse hemorrhages in the lungs

Question

Quizplus · Accepted Answer

Adult respiratory distress syndrome (ARDS) is caused by damage to the alveolar-capillary membrane, which leads to increased permeability of the alveolar walls, allowing for the interstitial and alveolar space to fill with excessive fluid and protein. This impairs gas exchange and leads to respiratory failure. Decreased surface tension in the alveoli (as seen in neonatal respiratory distress syndrome) and multiple diffuse hemorrhages in the lungs are not typically seen in ARDS.
