What is an AED?

An AED, or Automated External Defibrillator, is a portable device designed to analyze the heart rhythm of a person in sudden cardiac arrest (SCA).  If necessary, the AED will deliver a shock to help the heart re-establish an effective heart rhythm.  All AEDs on the market today are intuitive, easy-to-use, and can save a life.
