What is the first step in using an AED?

The first step in using an Automated External Defibrillator (AED) is to turn it on. Activating the AED immediately allows the device to begin its self-checks and guide the responder through the subsequent steps for use. The AED will provide prompts and visual or auditory cues that are crucial for ensuring proper application and use. By turning on the AED first, you can make sure you're following the correct protocol, and the device can start analyzing the situation as needed.

After the AED is turned on, the next steps involve attaching the pads to the patient’s chest and allowing the AED to analyze the heart rhythm. Without turning it on first, the AED cannot perform these functions, making it essential to follow this order to effectively assist in a cardiac emergency.
