Cardiopulmonary resuscitation (CPR) is a lifesaving technique useful in many emergencies, including a heart attack or near drowning, in which someone’s breathing or heartbeat has stopped. The American Heart Association recommends that everyone — untrained bystanders and medical personnel alike — begin CPR with chest compressions. This animation is used to educate medical professionals, emergency technicians and the general public about how CPR is performed to save lives. https://www.amerra.com.
