Episode notes
What is ARDS?
- ARDS (acute respiratory distress syndrome) is an acute, diffuse lung inflammation.
- It's characterized by poor oxygenation and reduced compliance, often leading to respiratory failure.
ARDS Pathophysiology
- ARDS is a final common pathway for various lung injuries.
- It involves inflammation, edema, alveolar collapse, and impaired gas exchange.
Lung Structure and ARDS Impact
- Normal lungs are highly efficient for gas exchange due to a large surface area.
- ARDS disrupts this structure, reducing surface area and increasing the work of breathing.
