How Does an AED Work?
An Automated External Defibrillator (AED) is a portable device used to detect cardiac rhythms and, if necessary, administer a shock to restore a normal heartbeat. During CPR, if an AED is brought to the scene for a rescuer to utilize, the first action should be to open the case and power on the device, unless the device powers on automatically when opened.
AED pads have images to show correct placement. Remove the plastic film to expose the adhesive side of the pads and attach them to the victim.
Quick Tip: Usually, AED adult pads can be used on victims 8 years and older.
- Turn on the AED
- Plug in the AED pads and place them on the victim
- Clear any contact with the victim to allow the AED to analyze the heart rhythm and listen for the AED's prompts
- The prompt will be either “No Shock Advised” or “Shock Advised”
- If the prompt is "Shock Advised", the device will give a warning of "Clear" before shocking
- Once "Clear" is heard, clear any contact with the victim and press the "Shock" button, then listen for the prompt to continue CPR
- If the prompt is "No Shock Advised", perform CPR for 5 cycles and then reanalyze
Special Considerations for Infants and Children
Special AEDs and/or AED pads are made for children and infants. An adult AED and/or AED pad should not be used on a child under the age of 8 or an infant.
