An AED is a portable electronic device that automatically diagnoses the life-threatening cardiac arrhythmias of ventricular fibrillation and ventricular tachycardia in the victim.
It is able to treat the victim through defibrillation, the application of electrical therapy which stops the arrhythmia, allowing the heart to reestablish an effective rhythm.
With simple audio and visual commands, AEDs are designed to be simple to use for the layperson.
USING THE AED
If an AED is available, immediately set it down next to the victim. Open the AED case and turn on the power. Locate the electrode pads inside the case and attach it to the victim. One electrode pad should be attached near the victim's right shoulder. The second electrode pad should be attached to the victim's lower left rib area. The idea here is that if you were to imagine a straight line from one pad to the other pad, that line would cross directly through the victim's heart.
Clothing and jewelry must be removed from the victim's chest or else it can interfere with the AED's readings.
While performing CPR, the AED will take measurements and give voice instructions. The AED will analyze the victim's heart rhyme and advise whether a shock is needed. If the AED announces not to touch the victim, stop CPR for a moment and wait for the AED to analyze the victim and announce when to continue CPR.
DELIVERING A SHOCK
When the AED recommends a shock, announce loudly to all bystanders to "Clear." Be absolutely certain that no one, including yourself, is touching the victim. Press the shock button.
Before and after delivering the shock, or if no shock is advised, continue to perform CPR and follow the AED's voice instructions.
The AED will continuously monitor the victim and may change its instructions at any time.
