What is the recommended sequence and limits for pediatric defibrillation energy?

• A. 2 J/kg; 4 J/kg; >4 J/kg to a max of 10 J/kg; Do not exceed adult dose
• B. 4 J/kg; 2 J/kg; >6 J/kg to max 20 J/kg; No limit
• C. 1 J/kg; 2 J/kg; 3 J/kg; 4 J/kg
• D. 2 J/kg; 2 J/kg; 2 J/kg; 2 J/kg

Answer: (A)

The main idea is using a safe, weight-based escalation for pediatric defibrillation that balances effectiveness with protecting the child's heart. Start with 2 J/kg for the first shock. If needed, give 4 J/kg for the second shock. If additional shocks are necessary, use energies above 4 J/kg but cap each shock at 10 J/kg, and do not exceed the device’s adult maximum energy. This pattern minimizes the risk of injury from overly high energy while still providing enough energy to terminate VF/pVT. Other sequences either start too high, fail to escalate properly, or ignore the per-shock energy cap, making them less appropriate for children.
