When using an AED on children older than 8 or weighing over 55 pounds, which pads should be used?

When using an AED on children older than 8 years or weighing over 55 pounds, it is appropriate to use adult pads. This recommendation is based on the understanding of the child's physiological needs and the efficacy of the shock delivered by the AED.

Adult pads are designed to deliver a higher energy level shock, which is typical for older children who are more similar to adults in size and body composition. Pediatric pads are specifically designed for younger children and infants and deliver a lower energy dose, which is not suitable for older children who fall into the category established by the question.

In essence, using adult pads for children who meet the specified age or weight criteria ensures that they receive the appropriate level of defibrillation, maximizing the chances of a successful outcome in a cardiac emergency.
