How Automated External Defibrillators Help Save Lives

With the advancement in technology, we’re seeing more and more products created to make our lives easier. In the case of automated external defibrillators (AEDs), these devices were created to help save lives when someone dies suddenly, due to a heart attack or other sudden cardiac arrest.


What are AEDs?


An automated external defibrillator (AED) is a device that monitors heart rhythms and can provide electrical shocks to restore a normal heart rhythm. These devices are typically found in hospitals and other places where someone may need immediate cardiopulmonary resuscitation (CPR).


How do they help save lives?


When someone experiences a heart attack, the first thing they might do is call for help. But often times, by the time emergency responders arrive, it is too late. Automated external defibrillators (AEDs) can help save lives by providing a shock to the heart that can stop or reduce the severity of a heart attack.

How do they work?


When someone has a cardiac arrest, their heart stops beating. Without treatment, they can die within minutes. Automated external defibrillator is usually deployed when someone has a cardiac arrest outside of a hospital setting. The first step is for the AED operator to identify the person who has collapsed. Next, they will check for any signs of life, like breathing or movement. If there is no response, the AED operator will activate the device and wait for it to deliver a shock. The shock can quickly restart the heart and save the person’s life.


When should someone use an AED?


AEDs can be helpful in situations where someone has sudden cardiac arrest. When someone experiences cardiac arrest, their heart has stopped beating and they cannot breathe on their own. The best way to save someone’s life is to get them CPR (cardiopulmonary resuscitation) started as quickly as possible. If CPR is not successful, an AED can help provide a jolt of electricity to help the person’s heart start beating again.




The automated external defibrillators have proven to be a life-saving technology, and they are commonly used in hospitals across the country. Automated external defibrillators are key in saving lives by providing an automated response to cardiac arrests.
