What is a critical first step when using an AED on a victim?

Turn on the AED device

The critical first step when using an AED (Automated External Defibrillator) on a victim is to turn on the AED device. Activating the AED is essential because it initiates the device's self-checks and prepares it to guide the rescuer through the steps necessary to provide assistance effectively. Once the AED is powered on, it typically provides audible and visual prompts that instruct the user on how to proceed, including placing the pads on the victim's chest and analyzing the heart rhythm. This step is foundational in ensuring the AED can perform its intended function of detecting any abnormal heart rhythms that may require defibrillation.

Following this initial action, the rescuer can then focus on other important steps such as ensuring the victim's position and checking responsiveness, but without powering on the AED, the device would not be able to assist in the emergency effectively.
