Revised Trauma Score (RTS) Calculator

RTS = 0.9368·GCS_pts + 0.7326·SBP_pts + 0.2908·RR_pts.

Compute the weighted Revised Trauma Score (Champion 1989) from the field GCS, systolic blood pressure (SBP), and respiratory rate (RR) using the standard 0–4 mapping for each variable and the regression-derived weights. RTS ranges 0 (worst) – 7.84 (best); ≤ 4 indicates a high-risk trauma needing immediate transport to a trauma centre.
