  1. ICU: Intensive Care Unit; SpO2 : saturation of peripheral oxygen; RR: respiratory rate; BP: systolic blood pressure; HR: heart rate; GCS: Glasgow Coma Score; OR: odds ratio; CI: confidence interval; Tvitals : Triage category determined by vital signs; Tcomplaint : Triage category determined by presenting complaint algorithm. Tfinal : final triage category.
