AEDs – The only effective intervention for sudden cardiac arrest. If an AED recognizes either of these rhythms, it will charge and indicate that a shock is advised, usually with a voice command. The benefit of the shock is to correct the abnormal electrical disturbance that is causing the irregular heart rhythm,...
What are the benefits of using an AED to treat cardiac arrest?
An AED is a portable lifesaving device that can help a person suffering from sudden cardiac arrest. When a person’s heart stops beating unexpectedly, rescuers can place the AED the person’s chest to deliver an electric shock to the heart to restart it, according to the American Heart Association (AMA).
What is an AED?
Automated External Defibrillator (AED): An AED is a small, portable device that analyzes the heart’s rhythm and prompts the user to deliver a defibrillation shock if it determines one is needed. Once turned on, the AED guides the user through each step of the defibrillation process by providing voice and/or visual prompts.

How long does it take to defibrillate a person?
Statistics and Advisory Statements: 1 The American Heart Association (AHA) states that 350,000 Americans die each year from sudden cardiac arrest (SCA), of those approximately 7,000 are children. 2 When SCA occurs, the AHA recommends defibrillation within 3-5 minutes, or sooner. On average, EMS teams take 6-12 minutes to arrive. 3 Survival rates drop 10% as each minute passes without defibrillation. While the national SCA survival rate is 5-10%, studies have shown that defibrillation within 3 minutes raises the survival rate to 74%. Timing is everything. 4 An Advisory Statement from the Pediatric Advanced Life Support Task Force (PALS), International Liaison Committee on Resuscitation (ILCOR) states: Automated external defibrillators (AEDs) may be used for children 0 to 8 years of age who have no signs of circulation.
What is sudden cardiac arrest?
Sudden cardiac arrest (SCA) is a condition in which suddenly and unexpectedly the heart stops beating due to a malfunction in the heart’s electrical system. The malfunction that causes SCA is a life-threatening abnormal rhythm, or arrhythmia. The most common arrhythmia is ventricular fibrillation (VF). When in VF, the heart’s rhythm is so chaotic (called “fibrillating”) that the heart merely quivers, and is unable to pump blood to the body and brain. Once a heart has entered VF, sudden cardiac arrest occurs. A victim in SCA first loses his or her pulse, then consciousness, and finally the ability to breathe. But all of this happens quickly – in a matter of seconds. Without immediate treatment from a defibrillator, 90-95 percent of SCA victims will die.
How long does it take for an EMS to arrive?
When SCA occurs, the AHA recommends defibrillation within 3-5 minutes, or sooner. On average, EMS teams take 6-12 minutes to arrive.

What does an AED do?
We’ve all seen the TV commercials that show people being saved by an AED, but what does it actually do? An AED is a device that can be used in conjunction with CPR to save someone who has experienced SCA. It sends electric shocks through the chest muscles and helps restore heart rhythm. The key takeaway from this blog post is not just how important an AED is for saving the lives of victims of SCA, but also how they are only effective when combined with quick-acting CPR. When you think about your workplace or school environment where there may not always be immediate access to emergency medical services, this knowledge becomes more crucial than ever before. If you want help understanding how the use of the lifesaving AED machine along with the quick use of CPR, contact AED USA today to learn more about training for SCA events in your home or organization today.
What does AED stand for in CPR?
AED stands for Automated External Defibrillator, this device can detect SCA by using an electric shock should it occur. AEDs are not used independently from CPR but rather in conjunction with the technique to save the victim’s life. More access to AED’s in public places for all first responders has a direct correlation to increased survival rates.
What is the difference between CPR and AED?
The difference between CPR with AED intervention and just CPR without is that an automated external defibrillator can detect SCA and provide the necessary electric shock needed to terminate it. A person who has AED intervention with CPR will have greater chances of survival than someone without AED intervention with or without a bystander performing chest compressions. The reason being is that if the victim is indeed suffering from SCA and the AED recognizes and shocks the heart into a normal rhythm, thereby establishing oxygenated blood pumping throughout the body, the victim would have a higher probability of making a full recovery. For this reason, AED training, CPR training along with the American Heart Association recommends the use of CPR in conjunction with an AED in case defibrillation is needed before trained medical professionals can arrive on the scene.
What is the purpose of CPR?
CPR stands for cardiopulmonary resuscitation which is a lifesaving technique to help keep someone’s heart beating and therefore circulating oxygen throughout the body during a sudden cardiac event. The early compressions to a person’s chest are often done by pushing on the chest at a rate of 100 times per minute, with depth that is enough to break up the obstruction in their airway.
What is the name of the device that is used when a person's heart stops beating?
Cardiopulmonary Resuscitation, or CPR, is used when a person’s heart stops beating. An Automated External Defibrillator (AED) is a device that can be used on people who are experiencing SCA and it’s often used in conjunction with CPR to save them.
Where do AEDs make contact with the body?
The electrodes pads must make contact with skin, usually around the victim’s torso near the anterior chest area. AEDs are not designed to be used for a complete shock, only as a backup in conjunction with CPR which consists of continued compression on the victim’s chest and breathing air into their lungs.
Can AEDs replace lifesaving care?
AEDs should never replace actual life-saving care by professionals but it does offer many benefits such as decreased time to defibrillation and increased survival rates from SCA when in public places where AED access is well distributed among first responders
