What is the correct procedure for using an AED?

The correct procedure for using an AED (Automated External Defibrillator) is to turn on the device and follow the prompts, then attach the pads. This approach is essential because the AED provides specific verbal and visual instructions that guide the user through the process, ensuring that the correct procedures are followed to maximize the effectiveness of the device. By turning on the AED first, the device can start analyzing the heart rhythm and prepare for delivering a shock if necessary when the pads are attached.

Following the prompts ensures that the rescuer is aware of what to do next and can perform the necessary actions without delay. The prompts may include instructions on when to attach the pads, how to place them correctly on the patient's chest, and when to stand clear for the shock to be delivered.

In contrast, turning the device off until help arrives would delay critical care, as immediate action is often required in cases of cardiac arrest. Ignoring prompts could lead to confusion and improper use, while attaching the pads before turning the device on does not allow the AED to analyze the heart rhythm first, which is a vital step in the process.
