At what age and weight can a passenger use the AED?

The age and weight guidelines for using an Automated External Defibrillator (AED) are crucial for ensuring safety and effectiveness in emergencies. The correct choice establishes that a passenger can use the AED at 8 years old and 55 pounds. This specification is based on safety protocols that take into account both the physical maturity and size of the child, ensuring that the pads of the AED can effectively deliver a shock if needed.

Using the AED on children younger than 8 years old or lighter than 55 pounds may not account for the size and developmental factors necessary for effective defibrillation. It's important that the equipment is appropriately matched to the passenger's age and weight to maximize the chances of successful resuscitation, minimizing the risks involved for younger or smaller individuals.
