AED Defined
An Automated External Defibrillator (AED) analyzes the heart's electrical rhythm for abnormalities. When needed, and AED administers a shock, called defibrillation, to a person suffering from sudden cardiac arrest. The shock may help the heart re-establish an effective rhythm and can increase the chance of survival. Housed in an easy-to-carry case, the unit contains electrode pads that are applied to the chest of the victim. It also contains diagrams of where to place the pads and directs the rescuer with concise and easy-to-understand voice prompts.
How It Works
Turn on the machine. A computerized voice prompts the professional or other trained rescuer through the steps of the process. After wiping dry the entire chest area, apply the two electrode pads to the specific sections of the victim's chest that are indicated in the diagram. Depending on the model of AED, you might need to plug the connector into the machine. The AED will analyze the victim's heart rhythm. If a shock is needed, the machine automatically charges and instructs the rescuer to stand clear of the victim. Some models automatically produce the shock. Others prompt the rescuer to press the shock button. After the shock has been administered, cardiopulmonary resuscitation (CPR) will need to be administered. It might be necessary to follow the CPR cycle with another shock. If the machine indicates that a shock is not advised, the rescuer may need to perform only CPR until professional help arrives.
Who Should Use An AED
Members of police, fire, EMT and medical departments regularly are trained and re-certified in CPR and AED. All others are encouraged to learn CPR and use an AED on adults and children. This knowledge will allow them to assist a victim until professional assistance arrives and it can help save a life. Classes are available through the American Red Cross and other organizations.
