Automated External Defibrillators (AED) are the most widely known medical devices – these are used to deal with cardiac arrest emergencies and prevent dire consequences. However, despite its efficiency and simple operation, a high percentage of the population doesn’t know how to use an AED or where to find one. In fact, research shows that only 3 in 10 workers are aware of a defibrillator in their workplace.

In this article, we will shed light on which scenarios a defibrillator can be of help and how to use them. Stick around to learn more!

When to Efficiently Use an AED – Various Scenarios Where Defibrillators Are Essential

Defibrillators are specialised medical equipment used to deliver a controlled electric shock to the heart, essentially “resetting” its electrical activity. Below are the scenarios where a defibrillator could help:

• Sudden Cardiac Arrest: A defibrillator can help increase a person’s survival chance during a sudden cardiac arrest. A cardiac arrest occurs when the heart suddenly stops beating effectively, leading to loss of consciousness and absence of pulse.
• Ventricular Fibrillation: Ventricular fibrillation is technically the underlying cause of a cardiac arrest. This condition occurs when the heart’s lower chambers (Ventricles) quiver chaotically instead of pumping blood leading to an electrical malfunction. Using a defibrillator helps deliver an electric shock which in turn restores the heart’s electrical system, bringing back the normal heart rhythm.
• Other Heart Rhythm Disorders: Defibrillators may be needed in other heart rhythm disorders like Long QT Syndrome, where the heart’s electrical system takes longer to recharge between beats, potentially leading to dangerous arrhythmias. An AED may also be used when a patient is still unresponsive after Cardiopulmonary resuscitation (CPR) has been performed. This is another heart rhythm disorder in which the patient does not pulse or respond.

You may also wonder whether a defibrillator can help someone experiencing a heart attack. Unfortunately, defibrillators are not used for heart attacks. While both emergencies involve the heart, there is a vast difference between the two.

A heart attack occurs when blood flow to the heart is blocked, usually by a clot damaging the heart muscle. The heart typically continues beating. When someone is experiencing a cardiac arrest, their heart suddenly stops beating effectively due to an electrical malfunction, referred to as ventricular fibrillation.

 Below are some of the signs and symptoms one may have during a cardiac arrest:

• The person suddenly collapsed on the ground.
• The person is unresponsive.
• The person is not breathing or only gasping.
• The person has no pulse.

If you see an individual with these signs, you must be prepared to use a Zoll Defibrillator or any AED available immediately. A delay in administering the shock decreases the chances of survival by 10%. Here is how: When ventricular fibrillation persists for more than 5 minutes, vital organs, including the brain, don’t get enough oxygen. By the 8-minute mark, the damage is often severe, significantly reducing the chance of recovery even if resuscitation is eventually successful. That being the case, knowing how to use a defibrillator before an emergency is a game changer.

A Step-by-Step Guide to How to Use a Defibrillator

Before we dive into how to use defibrillators, it is essential to note that Automated External Defibrillator suppliers provide different types of defibrillators. The most commonly used include fully automated defibrillators and semi-automatic defibrillators. Both of these medical devices are similar; the only difference is that semi-automated defibrillators require the user to press a shock button to administer shock, while fully automated defibrillators administer shock on their own.

Defibrillators from Zoll, whether fully automated or semi-automated, feature an analysis unit and two electrodes that should be placed on the victim’s chest. These specialised AEDs also have diagrams and instructions to help untrained individuals understand what is needed.

The two electrodes have to be the heart of the defibrillator. They must be well attached to the victim’s body for the defibrillator to conduct an analysis as well as administer an electric shock when needed. Below are the instructions to follow to administer shock effectively;

1. Activate the AED by pressing the power button. When the device is on, you should receive voice prompts and visual instructions.
2. Remove any clothing that may be covering the victim’s chest. This will give room for the safe placement of electrodes.
3. Place the two electrodes on the victim’s chest. You should receive a visual prompt showing you how and where to place them.
4. Allow the electrodes to conduct an analysis of the victim’s heart rhythm. Again, ensure no one is touching the patient at this stage for accurate analysis.
5. Once the analysis is done, the AED will send feedback on whether a shock is needed or not.
6. If a shock is needed, have everyone stand away from the body and refrain from touching the person. If you are using a semi-automated Zoll defibrillator, press the shock button to administer the shock. For anyone using a fully automated defibrillator, the device will make a countdown and administer the shock by itself.
7. After the shock is administered, resume CPR immediately as instructed by the AED.
8. When the victim’s heart rhythm has been revived, stay put and keep an eye on the victim to ensure they remain conscious. At no point should you remove the two electrodes placed on the victim’s chest. Keep the Zoll defibrillator on and wait for professional assistance.

Where to Find AEDs

AEDs are conveniently located in many public places where people are gathered. You can find them in:

• Airports and train stations
• Shopping malls and large stores
• Sports arenas and gyms
• Schools and universities
• Office buildings
• Community centres
• Hotels
• Public libraries
• Zoos

Look for wall-mounted cabinets with AED signs or symbols. Many buildings have signs directing you to the nearest AED. Some cities also have smartphone apps that show nearby AED locations.

Now that you know when and how to use adefibrillator, you are set to save a life in the event of a cardiac arrest. If you don’t have a defibrillator available, make sure to get one from the best Automated External Defibrillator suppliers. Consider the location and targeted population to choose the best.
