Public Access Automated External Defibrillators (AED)

Cardiac Arrest & AEDs

Cardiac arrest is when the heart suddenly stops beating, causing a lack of blood flow to all vital organs. If not treated immediately, the results can be deadly. An automated external defibrillator (AED) is a medical device that can be used during cardiac arrest to analyze heart rhythm and deliver an electrical shock (defibrillation) if needed to help the heart get back to an effective rhythm.

Maryland’s Public Access Automated External Defibrillator (AED) Program

The Public Access AED Program in Maryland promotes an increase in AED availability to help save lives during cardiac arrest. The State of Maryland has established a registry for all public access AEDs that:

  1. Allows the option to have AED locations made available to 911 dispatch to guide callers to the devices during an emergency; and
  2. Provides support to organizations who register their AED machines through maintenance emails, expiration alerts, and recall alerts.

Please visit the Maryland AED Registry to register an AED. (Recommended web browsers include Google Chrome or Mozilla Firefox).

To view the Maryland regulations for the Public Access AED Program, please visit the COMAR 30.06 – Automated External Defibrillator Program.
