Nearly 350,000 people die of sudden cardiac arrest each year. Currently, the chances of surviving sudden cardiac arrest (SCA) without the aid of an automatic external defibrillator (AED) are one in twenty. However, with an AED, chances of survival improve to one in three. The use of AEDs could save 100,000 lives per year!
What is SCA?
The heart normally has a rhythmic beat which causes the blood to move in a consistent, predictable way. When someone has an SCA event, the heart begins to pump irregularly and ineffectively. This is called ventricular fibrillation (VF). VF is not to be confused with the heart attack where blood flow to the heart muscle is blocked. With VF, the blood stops circulating adequately, breathing stops, and eventually the victim will die.
Another SCA event is ventricular tachycardia (VT), when the heart muscles start to “quiver” instead of working together to push blood through the system.
CPR alone does not replace defibrillation in an SCA incident. CPR can only assist the victim for a short time until medical help arrives. However, medical assistance can be many minutes away. According to the American Heart Association, the chances of survival decrease 10 percent with each passing minute that the heart beat is not returned to normal. Very few people have survived SCA after 10 minutes with no medical treatment.
Unfortunately, we don’t know why SCAs occur, nor how to prevent them. We do know, however, how to fix them if they occur—AEDs.
What is an AED?
You’ve seen full-sized defibrillators on television. When the doctor shouts “Clear” and shocks the victim, they are using a defibrillator. The AED works the same—it shocks the heart back into a normal rhythm to restore a pulse.
Manufacturers have developed lighter, smaller, battery-operated, computer-controlled models which nearly anyone can use.
Signs and symptoms of SCA
Symptoms of SCA are very sudden and dramatic. Typically, the victim will collapse, and show no sign of a pulse. At this point, emergency medical help must be summoned, and the AED used.
The victim’s chest is bared, all visible jewelry or medicine patches are removed, and the electrode pads are attached.
