Practical Prevention: How Defibrillators in Public Places Can Save Lives

PD Health and Medicine 2 MD000667 Sudden cardiac arrest victims feel fine one minute, then the next minute they are dead. Can automated external defibrillators (AEDs), make it possible to change the outcome? These devices are effective, fairly simple to operate, and now readily available in many public places. The idea is to have them handy for members of the public to use right away on cardiac arrest victims.

Frequency of Sudden Heart Death

In the United States, sudden heart death is a growing issue that can affect anyone. Researchers blame the trend on an increasing incidence of inactivity, obesity, and other risk factors. Heart disease is a major cause of death in the United States today, with many of these deaths happening suddenly and unexpectedly from cardiac arrest.

How Rapid Defibrillation Helps

During cardiac arrest, the heart stops pumping, and there is no effective heartbeat. The most common culprit is an irregular heart rhythm called ventricular fibrillation. The irregular rhythm causes the heart to fibrillate, or quiver uncontrollably, and renders the heart unable to pump blood around the body. This can lead to death in minutes. An important factor in surviving cardiac arrest is early defibrillation. Automated external defibrillators have the potential to improve survival rates. They can be readily available outside of a medical setting and they are relatively easy to operate.

Who Should Use an AED?

Increasingly, nonmedical people are being trained to use defibrillators. The American Heart Association promotes the use of AEDs by all emergency personnel. Additional people who may benefit from AED training include family and friends of persons at high risk and even employees at worksites or public places where large numbers of people gather.AEDs are usually put in areas where they will most likely be needed and where quick service by paramedics is not readily available. Common locations include airports, shopping malls, casinos, community centers, and sports or medical facilities. With more AEDs around, the key to safe and proper use is training. The American Heart Association and American Red Cross offer AED classes.
