What is the first action to take when an AED is nearby?

Turning on the AED is the critical first action to take when one is nearby during a cardiac emergency. This step is essential because the AED will provide voice prompts and visual instructions that guide the rescuer through the process of using the device effectively. The earlier the AED is activated, the sooner it can analyze the heart rhythm and advise whether a shock is necessary.

Having the AED activated promptly also helps to create a systematic approach to the resuscitation efforts. While other actions, such as calling for help or starting CPR, are important, they should follow the initial step of turning on the AED to ensure that the device can start analyzing the situation and provide guidance on what to do next. Engaging with the AED at the beginning streamlines the response and keeps the focus on delivering effective care to the victim.
