Accuracy of Focused Assessment with Sonography for Trauma (FAST) in Blunt Abdominal Trauma

Table 1

Accuracy of FAST examination according to SBP.

	Sensitivity (%)	Specificity (%)	PPV (%)	NPV (%)
Total	33.3	98.8	82.8	89.6
Initial SBP ≤ 90 mmHg	49.1	96.9	93.1	69.2
Lowest SBP ≤ 90 mmHg	48.3	99.0	95.8	80.2

SBP: systolic blood pressure; PPV: positive predictive value; NPV: negative predictive value. The lowest SBP was defined during initial resuscitation in the trauma bay.
