Question:
patho: alveoli gets full of "stuff" --> decreased ability to diffuse O2 --> decreased perfusion --> mix matched VQ --> lungs cant expand
causes:
- sepsis
- shock
- aspiration
- smoke inhalation
manifestations: 1-2 days after injury
- dyspnea, despite supplemental O2
- rapid, shallow respirations, tachycardia
- productive cough
- rales
- confusion (hypoxia)
- lethargy (increase CO2)
complications:
- respiratory failure
- fibrosis throughout lungs (if they live.. lungs will never be the same)
Answer:
acute respiratory distress syndrome (ARDS)
