An AED is a medical device that provides an external electric shock to the heart to a normal heart rhythm in patients who have a certain type of cardiac arrest, have a sudden cardiac arrest (SCA) have been known to recover. SCA is not the equivalent of a heart attack, nor are AEDs used to treat all my heart. Rather, AEDs are only indicated for the treatment of sudden cardiac arrest.
In most cases, SCA from ventricular fibrillation (VF) which causes a completeThe lack of heartbeat, which can be fatal within minutes. However, SCA can also ventricular tachycardia (VT), a rapid heartbeat that can occur after exercise and fever, or be the result of nervous excitement.
Sudden cardiac arrest can affect people of any age, race or sex. For example, electric shock, drowning, suffocation, and all the trauma that disrupt the heart rhythm. Although some individuals are genetically predisposed to SCA, most people with this condition have no symptoms or previousWarning. Often, when it fell on seemingly healthy young athletes during a game to read, SCA is the cause. But most of SCA occur in elderly males.
An AED is the appropriate emergency treatment in those cases in which the heart's electrical malfunction has stopped its normal rhythm. In these cases, the AED delivered a shock within the first 10 minutes of the SCA, to restore a regular beat.
Defibrillation can restore the heart out of rhythmif it is done in a few minutes after shutdown. According to the American Heart Association makes every minute that passes without defibrillation, the victim's chance of survival by 10 percent. This is significant when you consider how long it takes for the ambulance service (EMS) to respond to treat a victim of sudden cardiac arrest.
According to the researchers, to evaluate public access defibrillation programs, the average response time of EMS-shock interval called the United States probablymore than 5 minutes. The reaction times are very different and can do more in a very urban with heavy traffic or in remote rural settings.
The effectiveness of antiepileptic drugs
According to a recent study found that survival rates in Las Vegas casinos, among the first companies to implement the use of AEDs were considered, these devices have proven to be effective. The study, published in the October issue of 2000, The New England Journal of Medicine, found thatOverall survival rate in patients with ventricular fibrillation (VF) was 53 percent. This result is particularly impressive when you compare their success to the victims who do not receive defibrillation. Most studies show survival rates for VF / VT to about 10 percent. After the rapid access to an AED can improve survival rates by up to 40 percent. In simple language, is that four lives saved for every ten people affected.
The American HeartAssociation recommends that AEDs are available, where many people gather. These places are airports, convention centers, stadiums and arenas, large industrial buildings, skyscraper offices and large health and fitness facilities.
