How Does it Work?

The HeartMap Challenge is a multi-city community improvement project conducted by the University of Washington in collaboration with local agencies. A series of contests are being held where participants report where they find automated external defibrillators (AEDs) within the contest area. This information is used to help improve access to these life-saving devices when bystanders witness cardiac arrest.

AEDs located through the HeartMap Challenge are labeled so that they can be tracked. See sample labels.


  • Sudden cardiac arrest is one of the leading causes of death in the U.S. Over 350,000 people will suffer from sudden cardiac arrest this year. It can happen to anyone, anytime, anywhere and at any age. An AED is the only effective treatment for restoring a regular heart rhythm during sudden cardiac arrest.
  • The use of CPR dates all the way back to 1740.
  • The first out-of-hospital defibrillation device weighed over 100 pounds. AEDs now weigh less than 5 pounds.
  • About 75 percent to 80 percent of all out-of-hospital cardiac arrests happen at home, so being trained to perform cardiopulmonary resuscitation (CPR) can mean the difference between life and death for a loved one.
  • Effective bystander CPR, provided immediately after cardiac arrest, can double a victim’s chance of survival.
  • CPR helps maintain vital blood flow to the heart and brain and increases the amount of time that an electric shock from a defibrillator can be effective. For each minute defibrillation is delayed, the chance of survival is reduced approximately 10%.
