Automated External Defibrillator

What are automated external defibrillators (AEDs)?

The AED, or an automated external defibrillator, is used to help those experiencing sudden cardiac arrest. It is a sophisticated yet easy-to-use medical device that can analyze the rhythm of the heart and, if necessary, provide an electric shock or defibrillation to help restore efficient heart rhythm.

History of automated external defibrillator

Defibrillation was first performed in 1899 by two physiologists Provost and Batelli from the University of Geneva in Switzerland. They found that small electrical shocks could induce ventricular fibrillation.

The first use of a defibrillator in humans was made in 1947 by Claude Beck, professor of surgery at Case Western Reserve University. Beck first used the defibrillation technique on a 14-year-old boy who was undergoing surgery for a congenital breast defect.

In the 1960s, portable defibrillators were introduced for use in ambulances. Today, defibrillators are the only proven way to resuscitate a person with cardiac arrest and persistent ventricular fibrillation or ventricular tachycardia upon the arrival of rescuers.

Sudden cardiac arrest is a major public health problem, affecting 500,000 people each year. Sudden cardiac arrest can affect anyone, so it is important to be prepared to respond quickly to sudden cardiac arrest.

Having an automated external defibrillator (AED) accessible to deliver life-saving shocks quickly is the difference between life and death. When the victim experiences sudden cardiac arrest, with a shocking rhythm, every minute counts;

Every minute that the victim goes without defibrillation, the chances of survival decrease by 7% to 10%. Installing an automated external defibrillator in your area can enable on-site trained first responders or nearby first responders to provide lifesaving defibrillation treatment quickly and effectively.

How does an automated external defibrillator work?

  • A built-in computer checks the victim’s heart rate
  • By adhesive electrodes. The computer calculates
  • If defibrillation is necessary. If so, register
  • The voice asks the rescuer to press the shock button.
  • An automated external defibrillator, this shock surprises the heart in a moment
  • And disable all activity. Give the heart a chance
  • Start beating effectively. An audible prompt guides the user through the process. Automated external defibrillator only advise downloads
  • For ventricular fibrillation or other malignancy
  • A condition called pulseless ventricular tachycardia.

Who can use an automated external defibrillator?

Most AEDs are user-friendly and can be operated by non-medical personnel, such as firefighters, police officers, flight attendants. With rapid cardiopulmonary resuscitation (CPR) and emergency defibrillation, it can dramatically help increase a person’s chances of surviving sudden cardiac arrest.

Are automated external defibrillators safe to use?

Yes, AEDs are safe to use in all weather conditions. However, if possible, seek shelter and protect the victim from adverse weather. If the victim is in water, move them to a relatively dry area before using the automated external defibrillator.

Where should an automated external defibrillator be placed?

To ensure that your AED enclosure is accessible to anyone, even those in a wheelchair, in an emergency, it must be mounted 48 inches above the floor, in an unoccupied area. Make sure your employees can reach the AED with one hand to minimize response time.

AED’s Placement checklist:

  • Are your AEDs located in a clearly identified, well-lit, unbuilt space?
  • Isn’t it easy to reach and remove your AEDs with one hand?
  • Have you installed your AED in accordance with ADA guidelines?
  • Have you trained your employees in CPR and AED?
  • Do you have a DEA compliance management program or a preventive management program?
  • Does your AED have bleeding control kits, first aid kits, non-rubber gloves, CPR masks, scissors, razors, and absorbent pads?
