What is the correct sequence for using an AED in an emergency situation?

In an emergency situation where an AED (Automated External Defibrillator) is needed, the correct sequence is to first turn on the AED, followed by attaching the pads to the patient’s chest. Once the pads are securely in place, it's important to clear the area around the patient to ensure safety and prevent accidental shocks. After confirming that the area is clear, CPR should be started or continued as recommended by the AED's prompts.

This sequence ensures that the AED can analyze the heart rhythm efficiently and provides clear instructions on delivering a shock if necessary. It's critical to turn on the AED first so that it can provide audio and visual prompts that guide the rescuer through the process. Attaching the pads second allows for the device to assess the heart’s condition quickly. Clearing the scene ensures everyone's safety before administering any shocks, as AEDs can cause accidental injury if someone is touching the patient during operation. Starting CPR after this sequence ensures that the patient receives immediate assistance while the AED prepares to deliver a shock if needed.
