What is the first step when using an AED?

The first step when using an AED (Automated External Defibrillator) is to turn on the device and follow the voice prompts. This action is crucial because the AED provides specific, step-by-step instructions to guide the responder through the process of defibrillation and ensuring correct usage. Starting with the AED prompts not only helps to orient the responder but also activates the device's features, such as analyzing the heart rhythm and advising when to deliver a shock if necessary.

Following the voice prompts enhances the efficiency and effectiveness of the resuscitation effort during a cardiac emergency. It allows responders to focus on the necessary actions without missing critical steps in the process. By turning on the AED first, responders can also prepare to attach the pads correctly and analyze the patient’s heart rhythm in a timely fashion.
