Quick action by his parents who knew cardiopulmonary resuscitation (CPR) and the availability of an onsite automated external defibrillator (AED) saved his life. The American Heart Association wants a million people to learn CPR as part of National CPR & AED Awareness Week, June 1–7, to help save cardiac arrest victims like Matt. The week encourages the public to get CPR training and learn how to use an AED. It also encourages them to log their training on the association’s Web site. The site will feature a live map that will update in real time when people submit their information.
