An Automated External Defibrillator (AED) is an effective and user-friendly device that serves the purpose of restoring a heartbeat on those who have suffered from a cardiac arrest through the administration of defibrillation (shock). In a utopian society, these devices would be located in every public location; while this is not the case, AEDs can be found in many communal areas, such as schools (depending on your state) and shopping centers.

Unfortunately, it is safe to assume that most bystanders of a sudden cardiac arrest will hold no previous training experience regarding the matter, and may even be overwhelmed by the thought of operating such a device on another person. While we highly recommend everyone to be AED certified, there should be instructions included with the AED that allows people to operate it if followed accordingly. These devices are designed to be easy enough to use that even children can operate them without holding any previous knowledge in the matter.

When two people are present, it is important that one person is constantly performing chest compressions while the other gets the AED ready to operate. It is only when the AED is ready to deliver the shock that everyone should steer clear of the victim. Additionally, some AED packages include razors in the case that the victim is extremely hairy in the chest area and should be shaved before the electrodes are placed. Obviously, if pressed on time or if you do not have access to a razor, look to see if there is a second set of pads in the package. If so, attach the first set to the person and rip them out to remove the hair. You should then change into the second set of pads and stick them in the now smooth area to deliver the shock.

If I am unsure as to whether the person is suffering a sudden cardiac arrest, is an AED necessary or am I just going to harm them?

After the sticky pads (electrodes) are placed, they send signals to the device detailing the victim’s heart rhythm. If a shock is not necessary, it will not deliver one, so placing an AED on a person will not cause them any harm. However, not placing one when it is necessary will cost the person’s life.

I have never operated an AED before, where should I apply the pads?

A reason why AEDs are so user-friendly is because of the clear instructions provided with it. Most AEDs will have an easy-to-follow diagram that shows where the electrodes should be placed, while some might even play a video for you to follow along. In the case that the victim has an ICD or pacemaker, make sure that the pads are not placed directly on top or within an inch of the device. Also, if the ICD is delivering shocks, it is recommended that you wait 30 – 60 seconds before administering external defibrillation.

How do I know how much voltage to deliver with each shock as to not hurt the person but still get their heart beating again?

The sticky pads will retrieve information from the victim and send it to the AED, which will determine how strong of a shock should be delivered. Some AEDs use voice prompts to let you know when to press the button that will deliver the shock, while others will just tell you that a shock will be delivered without any outside intervention.
