Final answer:
In pediatric defibrillation, the first shock should be 2 joules/kg and the second and subsequent shocks should be 4 joules/kg, with adherence to AHA guidelines and proper AED training.
Step-by-step explanation:
In pediatric defibrillation, the energy delivered during a cardiac emergency is tailored to the child's size and situation. The first shock typically involves 2 joules per kilogram of the child's body weight. If subsequent shocks are necessary, the second shock and any subsequent shocks are usually increased to 4 joules per kilogram.
It's essential to follow the guidelines provided by the American Heart Association (AHA) or similar organizations, and to receive proper training on the use of an automated external defibrillator (AED) since it automatically analyzes the patient's heart rhythm and delivers the appropriate energy level based on the type of AED and embedded pediatric protocols.
