Massive Transfusion (ABC Score) - Scientific Formula
Emergency Medicine Equation
Standard Calibration Equation:
1 point each for: Penetrating mechanism, SBP ≤ 90 mmHg, HR ≥ 120 bpm, Positive FAST exam.
Accuracy Bounds & Limits:
While mathematical calculators evaluate demographic models, extreme variance (hyperthyroidism, dialysis cases, muscular bodybuilders, pregnancy) can trigger output errors. Weight and clearance assessments must follow separate personalized titration grids.
