A 4 y/o male is in V Fib. You have performed 10 cycles of effective CPR, administered EPI, and delivered one shock at the initial joules with no change on the ECG. You should defib at?

In pediatric resuscitation, defibrillation energy is given in weight-based steps, with the first shock typically at 2 J/kg and subsequent shocks at 4 J/kg if VF/VT persists. After you’ve delivered the initial shock and there’s no conversion, the recommended next defibrillation dose is 4 J/kg. This increases the chance of terminating the malignant rhythm while keeping myocardial injury risk reasonable. A smaller dose like 1 J/kg would be unlikely to succeed, and jumping straight to a much higher dose (such as 8 J/kg) is not the immediate next step in the protocol after a failed first shock.
