An automated external defibrillator (AED) is a portable device that delivers a shock to restore the heart’s normal rhythm. It is the only tool that can do this. In other words, it must be used to save someone who is experiencing cardiac arrest.
AED devices are smart devices. Once powered up, it provides voice prompts for the user. It evaluates the heart’s rhythm and then advises when a shock is needed. In other words, you can’t shock someone who doesn’t need it. You turn it on. The AED does all of the thinking.
Research shows that someone has the best chance of survival if an AED is used within the three minutes of a person collapsing. In fact, using an AED device increases the chances of survival by seventy percent.
