Know your AEDs

“The best and most beautiful things in the world cannot be seen or even touched. They must be felt with the heart” -Helen Keller.

I was told that is why we close our eyes when we pray, cry, kiss and dream. Let’s have a heart-to-heart conversation that may also save our lives.

Every year in the United States, over 350,000 people will suffer from sudden cardiac arrest. When this occurs, there are no truer words than “time is of the essence.” If it is not treated within minutes, it can kill. Sudden cardiac arrest does not discriminate. It can happen to anyone, anytime, anywhere and at any age.

Automated external defibrillators (AEDs) can be life-saving. If an electrical shock is delivered within the first minute after someone’s heart stops, studies have shown that it can be restarted and beat on its own in 90% of cases! And more importantly, AEDs are easy to operate even by someone with no medical background. You or a loved one may be able to save someone’s life, or possibly survive because of it.

Dr. Nina’s What You Need to Know: About Automated External Defibrillators (AEDs)

What are AEDs?

They are lightweight, battery-operated, portable devices that can check the heart’s rhythm and deliver an electric shock to the heart if someone has a cardiac arrest. The purpose of the electric shock is to put a temporary stop to the abnormal rhythm and give the heart a chance to resume a normal rhythm. This is similar to a “reset” button on your computer or a circuit breaker that will stop the flow of electricity when there is an overload or short-circuit.

What is sudden cardiac arrest?

Sudden cardiac arrest (SCA) is an abrupt loss of heart function. The heart has an internal electrical system that controls the rate and rhythm of the heartbeat. The electrical current causes the heart to contract and pump blood. Think of the circuitry in our homes and how electricity can turn on the lights or power a fan to rotate. Electricity drives action or movement.

If there is a problem with the heart’s electrical system, it can cause the heart to beat too fast, too slow, erratically, or stop altogether. This is known as an arrhythmia. If the arrhythmia results in the heart being unable to pump blood through the body, it can cause sudden cardiac arrest.

How do AEDs work?

When turned on or opened, the AED will provide voice instructions. Because minutes count, there can be no ambiguity. The AED will tell the rescuers to place adhesive electrodes, or pads, on the patient’s chest. The built-in computer then checks the heart rhythm. The computer determines if an electrical shock, or “defibrillation,” is needed and will announce to the rescuers to press the shock button on the device. After the shock is delivered, the device will analyze the rhythm and instruct the rescuer if another shock should be given.

Newer AED models have become so sophisticated that they do not require the operator to press a button to deliver a shock; the machine actually does it by itself! There is no room for any mistakes, and no one can be shocked unless needed.

Where are AEDs located?

They should be located in places where there are a lot of people: airports, places of worship, police stations, casinos, convention centers, hotels and shopping malls.

Who can use them?

Ideally, training on AED use and CPR is best. However, if a trained person is not immediately available, the device has been designed to facilitate its use. After all, someone’s life may depend upon it.

It may be you, your spouse, parent, child or friend that saves someone’s life, or has their life saved, because of an AED. Always call 911 if you see someone suddenly collapse. While waiting for the ambulance’s arrival, you can keep the patient alive. Studies have shown that when communities have AED programs, survival rates can increase to 49-74%! Let’s work together to continue to increase those odds.
