What energy should be used for subsequent shocks in pediatric defibrillation?

Explanation:
In pediatric defibrillation, energy dosing is weight-based to balance effectiveness with safety. The first shock is given at 2 J/kg, and subsequent shocks are delivered at 4 J/kg. This incremental approach raises the chance of successfully terminating the rhythm while keeping energy low enough to limit myocardial injury. Energies like 6 or 8 J/kg are higher than recommended for subsequent shocks and increase the risk of cardiac damage, whereas the first shock uses the lower 2 J/kg setting. Modern biphasic defibrillators use this 2 J/kg then 4 J/kg sequence, up to device limits.
