Emergency Transfusion Score (ETS)
Emergency Transfusion Score (Ruchholtz 2006): systolic BP and age bands plus free intra-abdominal fluid, unstable pelvis, scene arrival, traffic mechanism, and fall > 3 m; ≥ 3 flags a likely need for blood products.

Example
- Systolic BP
- 85 mmHg
- Age
- 40 years
- Free intra-abdominal fluid on FAST
- Yes
- Unstable pelvic fracture
- No
- Admission directly from the scene
- No
- Traffic mechanism
- No
- Fall > 3 m
- No
Result: Emergency Transfusion Score 5 — likely need for blood products (>= 3).
The tool opens with these values already filled in. Replace them with your own.
What the result means
- < 3
- Below the threshold.
- >= 3
- Likely need for early blood products. SBP band, free fluid, unstable pelvis, age band, mechanism. A risk score, not a transfusion order.
What you enter
- Systolic BP
