The demographic data (aside from location and duration) from three patients were unobtainable. More cardiac arrest episodes than patients are represented because some patients experienced more than one arrest event. ICU, Intensive Care Unit; ED, Emergency Department; VF/VT, ventricular fibrillation/ventricular tachycardia; PEA, pulseless electrical activity; ROSC, return of spontaneous circulation.
