FAST protocol plus additional views to assess for pneumothorax
Expansion
Extended FAST
Purpose
FAST plus bilateral anterior chest views for pneumothorax detection
Clinical Context
eFAST equals FAST plus lung ultrasound. Lung sliding (visceral-parietal pleural movement) present equals no pneumothorax; absent equals pneumothorax. Sensitivity approximately 95 percent for pneumothorax.

Key Points
- eFAST adds pneumothorax detection to FAST; absence of lung sliding indicates pneumothorax
