REMS from Olsson 2004 Table 1

REMS from Olsson 2004 Table 1: MAP, heart rate, respiratory rate, SpO2, GCS (RAPS 0–4, not 15−GCS), and age summed to a 0–26 total for nonsurgical adult ED in-hospital mortality. Deterministic published arithmetic with citation; not MEWS, NEWS, or APACHE II; not an ICU-admission order.
