When an adult has sudden cardiac arrest, his or her survival depends greatly on immediately getting CPR from someone nearby. Unfortunately, less than 1/3 of those people who experience a cardiac arrest at home, work, or in a public location get that help.

In 2011, Northwestern ED physicians Dr. George Chiampas and Dr. Amer Aldeen co-founded the Chicago Cardiac Arrest Resuscitation Education Service (CCARES) with the mission to increase the rate of survival of sudden cardiac arrest victims in Chicago by building relationships with City agencies, communities, and businesses to increase bystander CPR through education and awareness training.
