x402 APIPassing, checked 1 h ago

Acker 2015 SIPA: heart rate in bpm divided by cuff systolic pressure in mm Hg, rounded to two decimals. Elevated if the ratio exceeds the age-band cutoff: 1.22 (ages 4-6), 1.0 (7-12), or 0.9 (13-16). Ages 4-16 only; not for infants or adults 17 and older. Not a diagnosis of shock and not the adult shock-index greater-than-0.9 rule. magent does not measure vitals.
