x402 APIPassing, checked 4 h ago

Charles 2008 SMART-COP for intensive respiratory or vasopressor support in community-acquired pneumonia: SBP <90 (2), multilobar CXR (1), albumin <3.5 g/dL (1), age-adjusted RR (1), HR >=125 (1), new confusion (1), age-adjusted low oxygen (2), arterial pH <7.35 (2; omitted pH scores 0). Max 11. IRVS 0-2 low, 3-4 moderate, 5-6 high, >=7 very high. Not a site-of-care protocol. Albumin g/dL or g/L. Exactly one of PaO2, SpO2, or P/F.
