What should you ensure about the victim before using an AED?

Before using an Automated External Defibrillator (AED), it is essential that the victim is lying flat on their back. This position allows for proper placement of the AED pads on the chest, which is crucial for effective defibrillation. The pads must be applied without interference, and the flat position helps ensure that they are in contact with the skin and that the heart can be effectively assessed and treated.

Additionally, positioning the victim flat on their back increases safety during the defibrillation process. If the victim is sitting upright or on an elevated surface, it can complicate pad placement and may lead to ineffective shock delivery. Ensuring the victim has a pulse is not necessary before using the AED, as the device is meant to treat potential cardiac arrest situations, where a pulse is not present.
