About Automated External Defibrillators


Saving a life ….

Sudden Cardiac Arrest claims more than 295,000 lives a year in the US[1].  Ninety-five percent (95%) of the people who experience sudden cardiac arrest die from it – often within minutes.  Sudden cardiac arrest is caused by an abnormal heart rhythm.  The abnormal heart rhythm inhibits the flow of blood to the brain and other vital organs.  With each passing minute a person’s chance of surviving an arrest diminishes by 10%.  An AED can be used to administer a shock and restore a heart to normal rhythm.  The prompt use of an AED can increase survival from Sudden Cardiac Arrest to over 90%[2].   When trained personnel are available they should of course oversee the use of an AED, however, when they are not available, AEDs can be easily used by untrained persons.   AEDs are “automated” and simple to use. They are designed to automatically provide clear and simple life-saving audio instructions, which will guide an untrained person in their use.   In mock cardiac arrest trials, untrained sixth-grade children were able to effectively use AEDs without difficulty[3].

Cardiopulmonary resuscitation (CPR)

CPR is an effective first aid technique that is useful in many emergencies including cardiac arrest.  CPR training is highly recommended for everyone.  CPR training usually includes AED training.  It is likely that you have seen enactments of CPR use and have some understand of CPR.   American Heart Association advises that persons who are untrained in CPR should administer hands only chest compressions at the rate of about 100 compression per minute to someone who is not breathing and unresponsive.   For additional information provided by the Mayo Clinic see
