NHLBI Stops Enrollment in Study on Resuscitation Methods for Cardiac Arrest – 4
Narrator: This is NIH Health Matters. Researchers have studied two timing approaches to cardiopulmonary resuscitation—or CPR—an emergency procedure that uses chest compressions to keep blood circulating during cardiac arrest. Dr. George Sopko at the National Heart, Lung and Blood Institute explains, researchers compared patient survival rates after EMS providers performed at least 30 seconds or 3 minutes of CPR before assessing the need for defibrillation – an electric shock to the heart to restore its normal rhythm.
Dr. Sopko: Perhaps having about three minutes of CPR is very important sort of to optimize some of the circulatory conditions, and then defibrillate.
Narrator: But researchers discovered that different CPR durations were equally successful. For details, visit www.nhlbi.nih.gov. Health Matters is produced by the National Institutes of Health, part of the U.S. Department of Health and Human Services.
