RTS Coding Reference
| GCS | GCS code | SBP | SBP code | RR | RR code |
|---|---|---|---|---|---|
| 13–15 | 4 | >89 | 4 | 10–29 | 4 |
| 9–12 | 3 | 76–89 | 3 | ≥30 | 3 |
| 6–8 | 2 | 50–75 | 2 | 6–9 | 2 |
| 4–5 | 1 | 1–49 | 1 | 1–5 | 1 |

RTS = 0.9368 × GCS_coded + 0.7326 × SBP_coded + 0.2908 × RR_coded
Survival probability: Ps = 1 / (1 + e^−(0.4533 × RTS − 1.247))
Range: 0–7.84
Survival probability: Ps = 1 / (1 + e^−(0.4533 × RTS − 1.247))
Range: 0–7.84
Triage: T1 (Immediate, red) = life-threatening, salvageable. T2 (Delayed, yellow) = serious but stable. T3 (Minor, green) = minor injuries. T4 (Expectant, black/grey) = unsurvivable or RTS=0. RTS <4 indicates <50% survival probability.
