Question

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

1. damage leading to increased permeability of the alveolar walls

2. decreased surface tension in the alveoli

3. excessive fluid and protein interstitially and in the alveoli

4. multiple diffuse hemorrhages in the lungs

Answer 1

Adult respiratory distress syndrome (ARDS) involves increased permeability of alveolar walls, excessive fluid accumulation, and decreased surface tension in the alveoli.

Step-by-step explanation:

Adult respiratory distress syndrome (ARDS) is characterized by damage leading to increased permeability of the alveolar walls, excessive fluid and protein accumulation interstitially and in the alveoli, as well as a decrease in surface tension in the alveoli. This leads to impaired gas exchange and respiratory failure. However, multiple diffuse hemorrhages in the lungs are not typically associated with ARDS.
