About 75 percent of heart attacks occur in the victim’s home, and simple cardiopulmonary resuscitation can double—or even triple—the chance for survival. Not enough people, however, know how to administer proper CPR, says Dr. Michael Sayre, a professor of emergency medicine at The Ohio State University. To remedy this, Sayre, a 1980 graduate, helped the American Heart Association develop its new, less complicated CPR guidelines. People are now instructed to give 30 chest compressions, instead of 15, for every two breaths. “We believe that will make CPR easier to learn and remember,” he says.
About 281 international experts completed 403 reviews on 276 different topics before coming up with the updated guidelines. “We believe increasing the number of chest compressions will get more circulation of blood, making CPR more effective,” he says. “And we believe the simplification will help more people learn and use CPR when they need to.”
