When an Automated External Defibrillator (AED) arrives, what is the first step you should take?

The correct first step when an Automated External Defibrillator (AED) arrives is to turn it on. This action is crucial because the AED needs to analyze the heart rhythm of the patient. Turning the device on activates the voice prompts and visual instructions that guide the responder through the subsequent steps.

Once the AED is powered on, it will instruct the user on what to do next, which includes applying the pads to the person’s chest. Thus, the device's functionality is paramount to ensure that the lifesaving protocols are followed correctly. The voice prompts will help to maintain a structured approach, which is vital during such high-pressure situations.

While placing the pads, clearing the area, or checking for a pulse are also important actions in the process of responding to a cardiac emergency, they should follow the activation of the AED.
