x402 APIPassing, checked 47 min ago

Yücel 2006 TASH (Trauma Associated Severe Hemorrhage): seven independent nested less-than point bands for arrival SBP, hemoglobin, intra-abdominal fluid, complex long-bone/pelvic fracture AIS, heart rate, base excess, and male sex; max 28. Highest matching band only (do not stack). Deterministic published arithmetic with citation; not a transfusion or MTP order; not ABC (assessment of blood consumption). Caller assigns FAST and AIS; magent does not read imaging.
