Trauma Score for Survival Probability

The Trauma Score for Survival Probability is a scoring system that predicts % probability of survival from trauma. 5 items are factored into the total score. The individual scores from each of these 5 items are summed and a total score is calculated. The lower the score, the worse the prognosis.

Respiratory rate

10-24 (4 points)
15-35 (3 points)
>35 (2 points)
<10 (1 point)
0 (0 point)

Respiratory effort

Normal (1 point)
Shallow or retractions (0 point)

Systolic blood pressure (mmHg)

>90 (4 points)
70-90 (3 points)
50-69 (2 points)
<50 (1 point)
No carotid pulse (0 point)

Capillary refill

Normal (<2 seconds) (2 points)
Delayed (>2 seconds) (1 point)
No capillary refill (0 point)

Glasgow coma scale score

14-15 (5 points)
11-13 (4 points)
8-10 (3 points)
5-7 (2 points)
3-4 (1 point)
