Management of cardiac arrest due to VF or VT. If metabolic acidosis persists after successful defibrillation and with adequate ventilation, also consider administration of 1 meq/kg NaHCO₃. CPR, cardiopulmonary resuscitation; PCI, percutaneous coronary intervention; ROSC, return of spontaneous circulation; VF, ventricular fibrillation; VT, ventricular tachycardia.
