What is AED?
AEDs or Automated External Defibrillators are small devices that look at a person's heart rhythm through special pads placed on the person’s chest. The AED can recognize ventricular fibrillation (VF), also known as "sudden cardiac arrest" (SCA). AEDs are designed to be used by "first responders". If SCA is present, an AED will determine that, and will actually talk the responder through some very simple steps to defibrillate.
A heart attack occurs when the arteries that supply blood to the heart become blocked, the flow of blood which carries oxygen to the heart is slowed or stopped, and the muscle fibers contract chaotically rather than in synch with each other as they normally do.
When a person suffers a sudden cardiac arrest, chances of survival decrease by 7 to 10 percent for each minute that passes without defibrillation. A victim's best chance for survival is when there is revival within 4 minutes.
Who Can Use an AED?
Anyone, even a child from 11 years of age and up can be trained to use
an AED.
AEDs use embedded computer chips to analyze the rhythms, making it possible for non-medical professionals to provide the same vital service without risking an accidental shock.
Are There Limits As to Who the AED Can Be Used On?
Children
over 55 lbs or 8 years of age are defibrillated as adults. AED defibrillation
therapy is appropriate for infants and children, as well as adults, as
long as the appropriate pads are used.
Are There Any Warning Signs of SCA?
No, and unfortunately,
the first sign of heart problems in most men is sudden cardiac arrest.
SCA claims more than 350,000 lives each year, primarily because lifesaving
treatment does not reach the victims within the first critical minutes.
Does the AED Take the Place of CPR?
No. The AED is part of CPR. For maximum benefits you must use the two tools together!
Can I Hurt Someone with an AED?
No. If you
need to use an AED, the victim of SCA is essentially dead. Early defibrillation
represents that person’s only chance for survival. Simply, AEDs will not
shock someone who does not need to be shocked.
What About Using an AED on Metal or Wet Surfaces?
Most
AEDs are self-grounded and can be safely used in wet environments and
on metal surfaces with no risk to the victim or rescuer.
