What is the first step when using an AED after the victim is secured?

The first step when using an Automated External Defibrillator (AED) after the victim is secured is to turn the AED on. This action activates the device and initiates the prompts that guide the user through the process of attaching the pads, analyzing the heart rhythm, and delivering a shock if needed. It is crucial to power on the AED immediately, as this allows for timely assessment of the victim's condition and ensures that the defibrillator can provide the necessary interventions without delay.

While placing the pads on the chest, assessing the pulse, and calling emergency services are all important steps in the overall response to a victim in cardiac arrest, turning on the AED is the initial action required to utilize the equipment effectively. Once the AED is powered on, it will provide audible instructions to the responder, which makes the process smoother and ensures that critical steps are not overlooked.
