Revised Trauma Score (RTS) Calculator | HealthCalculum

Assess trauma severity using Glasgow Coma Scale, Blood Pressure, and Respiratory Rate.

Important Medical Disclaimer

This calculator is an educational and clinical decision support tool. Results DO NOT replace professional medical evaluation, laboratory tests, or clinical judgment. Always consult a qualified healthcare professional for diagnosis, treatment, and clinical decisions. Calculations are based on scientifically validated formulas but may not be applicable to all patients.

Calculate RTS

Note: Use in conjunction with clinical assessment. RTS is a triage tool to evaluate trauma severity.

What is RTS (Revised Trauma Score)?

The Revised Trauma Score (RTS) is a physiological scoring system used to quantify the severity of traumatic injuries. Developed by Champion et al. in 1989, RTS uses three vital parameters (Glasgow Coma Scale, Systolic Blood Pressure, and Respiratory Rate) to produce a numerical score from 0 to 12 points. Lower scores indicate greater trauma severity and worse prognosis. It is widely used in pre-hospital and in-hospital emergency services for triage, survival prediction, and decision-making for transfer to trauma centers.

Scoring System

GCS (Glasgow Coma Scale)

13-15 = 4 points
9-12 = 3 points
6-8 = 2 points
4-5 = 1 point
3 = 0 points

SBP (Systolic Blood Pressure)

>89 mmHg = 4 points
76-89 mmHg = 3 points
50-75 mmHg = 2 points
1-49 mmHg = 1 point
0 mmHg = 0 points

RR (Respiratory Rate)

10-29/min = 4 points
>29/min = 3 points
6-9/min = 2 points
1-5/min = 1 point
0/min = 0 points
