Laboratory, EKG, and vital sign variables recorded at earliest value from admission. Glasgow Coma Scale values recorded post return of spontaneous circulation (ROSC).

CK-MB: Creatine Kinase Muscle/Brain; CK: Creatine Kinase; BUN: Blood Urea Nitrogen; Cr: Creatinine; Hgb: Hemoglobin; K: Potassium; Ca: Calcium; Mg: Magnesium; EKG: Electrocardiogram; QTc: Corrected QT interval; WBC: White Blood Cell; SpO2%: Pulse Oximetry

*p-values calculated from two-sample t-test for continuous variables and Fisher's exact test for categorical variables.

**p by Fisher's exact test for overall oxygen delivery.
