Acronym

eFAST - Extended FAST

Extended FAST

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.

  • FAST
  • Trauma imaging

Key Points

  • eFAST adds pneumothorax detection to FAST; absence of lung sliding indicates pneumothorax
