Map of locations of AED (automated external defibrillator) at University of Tsukuba

An AED (automated external defibrillator) is a medical device which gives electric shocks to a heart that is undergoing sudden cardiac arrest. They help an abnormally beating to recover its natural rhythm. Since July 2004, in Japan, AEDs can be used by non-medical people to resuscitate those who are suffering cardiac arrest. To save the life of someone who is suffering cardiac arrest, it is important to immediately: (1) inform emergency personnel (by calling 119), (2) perform CPR (cardiopulmonary resuscitation), (3) defibrillate using an AED, and (4) transport the person to a hospital.

To use an AED you have to: (1) push the switch to get it started, (2) attach the electrode pad to the person’s chest, and, if necessary, (3) push the button to start the electrical current. Furthermore, voice instructions are given by the equipment.


Although they can be easy to use, you can receive a proper training from the Japanese Red Cross Society, fire department, etc., so that you can save someone’s life. We especially recommend that members of athletic clubs learn how to use it properly. Please learn where you can find AEDs on campus.
