An AED, or automated external defibrillator, is used to help those experiencing sudden cardiac arrest. It's a device that can analyze the heart's rhythm and, if necessary, deliver an electrical shock, to help the heart re-establish an effective rhythm.
There are two AEDs located on campus for emergency use. One is in the hallway in the Athletic & Recreation Building, outside the main office. The other is located in the Police and Public Safety office in the Nittany Court E-F building.
See the Red Cross’s description of how to use an AED in an emergency.
