Comparison of Four views versus Single View for Pneumothorax

Ultrasound is great at diagnosing pneumothorax. This is especially important in the trauma patient, where it has become integrated into the extended FAST exam. I think we are all wondering if we can (safely) get away with a quick look in a single space bilaterally to rule out a significant pneumothorax. This study prospectively evaluates this question to determine how well 1 view compares to 4 views in finding a pneumothorax in the trauma patient.
