Automated external defibrillators (AEDs)

Automated external defibrillators, or AEDs, will automatically analyze a patient's ECG and, if needed, deliver a defibrillating shock to the heart. The basic function of an AED is similar to that of a traditional defibrillator/monitor, but AEDs are much easier to use. As such, these devices can be used by a variety of medical and nonmedical personnel after only minimal training. The use of AEDs by nonmedical personnel (e.g., security guards, flight attendants) is often referred to as public access defibrillation, or PAD. In this Evaluation, we present our findings for eight newly evaluated models from five suppliers. We also summarize our findings for three previously evaluated models that are still on the market. We rate the models for first-responder use and for PAD use. Our ratings apply to the use of these devices both within the hospital and in the prehospital environment.
