What does the E-FAST exam extension add to the FAST exam?

• A. Adds evaluation for pneumothorax, pleural effusion, and other thoracic injuries.
• B. Used to assess abdominal organ perfusion.
• C. Replaces FAST as primary survey.
• D. Requires CT confirmation.

Answer: (A)

Extending the FAST exam to include the chest adds the ability to look for thoracic injuries at the bedside. The E-FAST combines the abdominal/pericardial assessment of FAST with ultrasound views of the lungs and pleural spaces, so you can quickly identify pneumothorax, pleural effusion, and other chest injuries that can threaten ventilation or circulation. This rapid chest assessment supports timely interventions (like chest decompression or drainage) while continuing resuscitation. It does not replace the FAST as part of the primary survey, and CT confirmation isn’t required for initial decision-making if ultrasound findings guide management.
