Automated External Defibrillator (AED) Devices

What AED models are available on the market?

In the United States, there are currently six companies that have the Food and Drug Administration’s Pre-Market Approval-510k for either a single AED or multiple AED models. AEDs are an extremely important tool that helps emergency responders save countless lives each year.

The FDA strictly monitors and regulates the approval and sale of AEDs to ensure only effective and safe equipment is offered and used. Anyone can purchase an AED but a prescription from a licensed physician or medical professional is required before a unit can be delivered by the retailer or manufacturer. The American Heart Association among other relevant healthcare authorities strongly recommend having an AED always available, particularly at arenas, public parks, auditoriums and any other large public venue.

All six of the companies listed below offer several different models of AEDs with various features and options available. While many of the AED models available are intended for use by those who have limited experience with using such equipment, it is important to complete proper training before using an AED.
