Figure 1From: Repeated epinephrine doses during prolonged cardiopulmonary resuscitation have limited effects on myocardial blood flow: a randomized porcine study Experimental time line. MCC = mechanical chest compressions, VF = ventricular fibrillation, CPR = cardiopulmonary resuscitation, EPI = epinephrine, defib = defibrillation, min = minutes, ROSC = return of spontaneous circulation, Drug administration; either 0.02 mg EPI/kg/dose or 0.03 mg EPI/kg/dose or NaCl , was administrated after 4 minutes of MCC and then every 3rd minute during the 15 minutes of MCC.Back to article page
