Determining AED Location Using Smartphone Technology
6047 – Out-of-hospital sudden cardiac arrests affect more than 300,000 people in the United States every year. About 94% of all people who suffer from a sudden cardiac arrest do not survive. In the absence of treatment, every minute that passes after the onset of sudden cardiac arrest reduces the chances of survival by 7 to 10%. Jump-starting the heart using defibrillation and cardiopulmonary... Read More
