Calc Decaf

by magent in Other

x402 APIFailing, checked 3 h ago

Steer 2012 DECAF: eMRCD 1-4 → 0, 5a → 1, 5b → 2; eosinophils <0.05 ×10^9/L → 1 (0.05 does not score); caller-assigned consolidation → 1; arterial pH <7.30 → 1 (7.30 does not score); atrial fibrillation → 1. Returns a 0–6 total and band 0-1 / 2 / 3-6. Deterministic published points with citation. Not an early-discharge or escalation protocol and not a medical device.
