When using an AED without a dose attenuator on a child, what must be avoided?

When using an AED on a child without a dose attenuator, it is crucial to ensure that the pads do not touch each other. If the pads make contact, it can result in ineffective transfer of the electrical shock to the child's heart, potentially diminishing the chances of restoring a normal rhythm. Proper pad placement is essential to maximize the efficacy of the shock delivered by the AED.

Using adult pads is typically acceptable in emergencies when pediatric pads are not available, although they may be larger and cover more area. A high-voltage setting is not applicable to most modern AEDs since they are designed to automatically adjust to the appropriate level of energy needed for the patient. Applying pads simultaneously is not generally a concern with AEDs, as they are designed for a specific sequence of operations, and they should be placed in the indicated positions while ensuring that no other action interferes with their operation.
