If the cardiac arrest is witnessed or downtime is shorter than 4 minutes, one shock may be administered immediately if the patient is in VF or pulseless VT followed by five cycles of CPR. If the patient is in VF or pulseless VT, shock the patient once using 200 J on biphasic (on equivalent monophasic, 360 J).
