  1. aSAPS II: Simplified Acute Physiology Score II; ROSC: return of spontaneous circulation; epinephrine dose: cumulative dose of epinephrine required during initial resuscitation; PCI: percutaneous coronary intervention; MTH: mild therapeutic hypothermia; SAP: systolic arterial pressure; PaO2/FiO2 ratio, ratio of partial pressure of arterial oxygen to the fraction of inspired oxygen. Numbers between brackets are percentages or 25th to 75th percentiles.
