That's a tough one: If the arrest is from heart rhythm problem, then good BLS (=CPR) + defibrillation can at least temporarily save 20-60% (studies vary a LOT). When CPR used on terminally ill pts from perceived obligation "to try," rate more like 4-8%. Combined, about 15% respond positively to get to ICU to work on fixing what caused the arrest.
