Get the Assist: Save a Teammate’s Life

Defibrillation is the only treatment proven to restore a normal heart rhythm. When used on a victim of SCA, the automated external defibrillator (AED) can be used to administer a lifesaving electric shock that restores the heart's rhythm to normal. AEDs are designed to allow non-medical personnel to save lives.

Only minutes. Defibrillate within three minutes and the chances of survival are 70 percent. After 10 minutes, the chances of survival are very slim.

Two pads, connected to the AED, are placed on the patient's chest. A computer inside the AED analyzes the patient's heart rhythm and determines if a shock is required to save the victim. If a shock is required, the AED uses voice instructions to guide the user through saving the person's life.

AEDs make it possible for more people to respond to a medical emergency where defibrillation is required. Because AEDs are portable, they can be used by nonmedical people (lay-rescuers). They can be made part of emergency response programs that also include rapid use of 9-1-1 and prompt delivery of cardio pulmonary resuscitation (CPR). All three of these activities are vital to improving survival from SCA.

Non-medical personnel such as police, fire service personnel, flight attendants, security guards and other lay rescuers who have been trained in CPR can use AEDs.

Although formal training in the use of an AED is not required, it is recommended to help the rescuer increase their comfort and level of confidence. However, AEDs are intended for use by the general public. Most AEDs use audible voice prompts to guide the user through the process.

AEDs are safe to use by anyone. Some studies have shown that 90 percent of the time AEDs are able to detect a rhythm that should be defibrillated. This data suggests that AEDs are highly effective in detecting when (or when not) to deliver a shock.

All first-response vehicles, including ambulances, law- enforcement vehicles and many fire engines should have an AED.

AEDs also should be placed in public areas such as sports venues, shopping malls, airports, airplanes, businesses, convention centers, hotels, schools and doctors' offices. They should also be in any other public or private place where large numbers of people gather or where people at high risk for heart attacks live. They should be placed near elevators, cafeterias, main reception areas, and on walls in main corridors.

AEDs save lives. When a person has a sudden cardiac arrest, the heart becomes arrhythmic. Every minute that the heart is not beating lowers the odds of survival by 7-10 percent. After 10 minutes without defibrillation, very few people survive.

AEDs are very easy to use. An AED can be used by practically anyone who has been shown what to do. In fact, there are a number of cases where people with no training at all have saved lives.

AEDs are safe to use by anyone who has been shown how to use them. The AED's voice guides the rescuer through the steps involved in saving someone; for example, "apply pads to patient's bare chest" (the pads themselves have pictures of where they should be placed) and "press red shock button." Furthermore, safeguards have been designed into the unit precisely so that non-medical responders can't use the AED to shock someone who doesn't need a shock.

State and federal "Good Samaritan" laws cover users who, in good faith, attempt to save a person from death. To date, there are no known judgments against anyone who used an AED to save someone's life.
