"Every three days, more Americans die from sudden cardiac arrest than the number who died in the 9-11 attacks. You can lessen this recurring loss by learning Continuous Chest Compression CPR, a hands-only CPR method that doubles a person’s chance of surviving cardiac arrest. It’s easy and does not require mouth-to-mouth contact, making it more likely bystanders will try to help, and it was developed here at the University of Arizona College of Medicine. 'This video is worth sharing,' said Gordon A. Ewy, MD, director of the UA Sarver Heart Center and one of the research pioneers who developed this method.*"
