Automated External Defibrillator

AED device ready for use

Defibrillators are critical medical devices designed to restore normal heart rhythm by delivering an electric pulse or shock to the heart. They play a vital role in preventing or correcting arrhythmias, which are problems with the rate or rhythm of the heartbeat. Defibrillators are also essential in resuscitating individuals whose hearts have stopped suddenly.

There are several types of defibrillators, each serving different purposes:

• Automated External Defibrillators (AED) are portable devices found in many public spaces, intended to be used by anyone, even without medical training, to save lives during sudden cardiac arrest.
• Implantable Cardioverter Defibrillators (ICDs) and Wearable Cardioverter Defibrillators (WCDs) are designed for individuals at high risk of life-threatening arrhythmias, offering continuous monitoring and treatment.

How Defibrillators Work

Defibrillators, including AEDs, ICDs, and WCDs, are designed to detect arrhythmias and restore normal heart rhythm through an electric shock. Here's how each type works:

Automated External Defibrillators (AEDs)

AEDs are lightweight, portable, and designed for emergency use in sudden cardiac arrest. They analyze the heart's rhythm and, if necessary, direct the user to deliver a shock to restore normal rhythm.

Implantable Cardioverter Defibrillators (ICDs)

Surgically placed in the chest or abdomen, ICDs monitor for arrhythmias and deliver shocks to correct them. They can administer both low-energy and high-energy shocks to manage abnormal heart rates or rhythms.

Wearable Cardioverter Defibrillators (WCDs)

WCDs are non-invasive devices worn on the body, monitoring the heart's rhythm and delivering shocks when needed. They are typically used temporarily, during periods of heightened risk.

Indications for Use

Defibrillators, including AEDs, ICDs, and WCDs, are vital for treating sudden cardiac arrest and managing arrhythmias in individuals of all ages, from children to adults. They are especially recommended for:

• Individuals who have survived sudden cardiac arrest.
• Those with a genetic predisposition to arrhythmias.
• Patients recovering from a heart attack.
• Individuals waiting for or recovering from heart transplant surgery.

Emergency Use of AEDs

In cases of sudden cardiac arrest, immediate action is crucial. AEDs are designed for quick use in public settings, and their accessibility can make the difference between life and death. Familiarity with the location of AEDs in public venues, as well as how to use them, can empower individuals to act swiftly and effectively in an emergency.

Accessibility

AEDs are widely available in public spaces, including shopping malls, airports, and sports venues, to ensure that bystanders can respond quickly to sudden cardiac arrest. Home-use AEDs are also available, providing additional security for individuals at risk.
