What is a defibrillator?
A defibrillator is the device that generates an electrical shock to the heart muscle to reverse the
effects of ventricular fibrillation. Specifically, an Automated External Defibrillator (AED) is the type
of defibrillator used on-site during an SCA. These portable defibrillators are the only proven way to
resuscitate a person, outside of the hospital environment, who has had a cardiac arrest and who is still
in persistent ventricular fibrillation.
You may have seen AEDs displayed in public areas such as airports, community buildings and corporate
offices. They are ready for immediate use by people just like you.
How does it work?
It is important to note that cardiopulmonary resuscitation (CPR) must be provided along with
defibrillation to treat an SCA victim. But CPR alone may not convert the heart to its proper rhythm.
Typically, CPR is performed first and then a shock from the defibrillator is applied.
Ease of operation is characteristic of today’s advanced defibrillation technology.
Anyone can do it,
simply.
Audio instructions are clearly spoken by the machine to coach you through the process.
No prior medical knowledge is required. The onboard computer will assess the condition of the victim
and determine if a shock to the heart is necessary. The victim cannot be harmed accidentally.
If a shock is not required, the activation button will not work.
Where do I find one?
The chaos of an emergency situation can be overwhelming for anyone. You may understand how defibrillators work,
but where do you find one when it’s needed?
International Liaison Committee on Resuscitation (ILCOR) has developed a universal sign indicating the presence of an
Automated External Defibrillator. It is designed to assist in rapidly identifying the location of an AED in public places.
Finding and using a defibrillator as fast as possible can improve chances of survival for a victim of sudden cardiac arrest.
You can save a life, when you easily locate an AED.
