---
1. Introduction
ARDS is a life-threatening condition characterized by sudden onset of severe respiratory
failure, caused by diffuse alveolar damage and impaired gas exchange.
Key Points:
Often develops after severe illness, trauma, or infection
High mortality rate if not recognized and managed early
Requires intensive care and mechanical ventilation in severe cases
---
2. Causes / Risk Factors
, Direct Lung Injury:
Pneumonia
Aspiration of gastric contents
Inhalation injury (smoke, chemicals)
Indirect Lung Injury:
Sepsis
Severe trauma or burns
Pancreatitis
Massive transfusions
