What is the first step in using an AED?

The first step in using an Automated External Defibrillator (AED) is to turn it on. This action is crucial because activating the AED initiates its self-check process and prepares the device to guide the rescuer through the defibrillation process. Once powered on, the AED will provide audible and visual prompts that instruct you on the next steps, such as applying the pads to the patient’s bare chest. This immediate activation ensures that you have the necessary prompts and can begin using the device effectively for the person who may be experiencing a cardiac event.

Turning on the AED before any other steps ensures that it is ready to assess the heart rhythm and deliver a shock if necessary, thereby maximizing the chances of a successful resuscitation.
