Automatic Defibrillator , also known as AED (automatic external defibrillator), is a small, lightweight and portable device that delivers an electrical shock (defibrillation) to the heart of a person who is experiencing sudden cardiac arrest.
In other words, Automatic Defibrillator is a life saving medical device with a light and useful design to deliver electric shock (defibrillation) to the patient in the event of a sudden cardiac arrest. Automated defibrillators are designed to be used by anyone who does not have medical training but has had training in first aid.
The AED – automated defibrillator – is designed especially for first responders, and is used until emergency paramedics arrive at the scene.
The early defibrillation, a treatment for sudden cardiac arrest, may enable the heart to beat at a rhythm that maintains circulation once again, and can be lifesaving.
In some developed countries, it is compulsory to make automatic defibrillators available and easily accessible in crowded places such as stadiums, shopping malls, airports etc.
Even though under ideal conditions automatic defibrillators should be used by certified first responders, in some countries the use of AED defibrillator is permitted without any certification, as the device can be successfully used by people without any training, due to the audible commands and guidance they provide.
Automatic defibrillators can be used at home, in the work place or in public places by anyone who is not a medical expert but who has had the appropriate training for using the device. The advantages of having an automatic defibrillator is that it helps to keep the patient alive or to resuscitate the patient who is having a heart attack / sudden cardiac arrest until a professional emergency team arrives on the scene. That said, if a person who is having a heart attack is not defibrillated as quickly as possible, their chance of survival declines with every passing minute.
