What type of AED pads should be used for a child or infant weighing 55 pounds or less?

Using pediatric pads for a child or infant weighing 55 pounds or less is essential due to their design, which is appropriate for the smaller body size and lower electrical current required for effective defibrillation. Pediatric pads reduce the risk of delivering an inappropriate amount of energy that could potentially harm a smaller patient. They are specifically made to ensure safe and effective administration of electrical shocks, which consider the child's developing heart and body.

Adult pads, while they may still work, deliver a higher energy level that is not tailored for children and may not result in as effective defibrillation. Training pads are designed for practicing CPR and AED use, not for actual emergency situations. Therefore, pediatric pads are clearly the best choice when treating children and infants in emergencies.
