Bystander CPR improves survival. As per the AHA (American Heart Association), there are up to 350 000 cases of cardiac arrest outside of the hospital each year. With more and more people being trained to do CPR the out of hospital CPR survival rate is increasing. An ultimate goal would be for each family/house to have at least one person who is able to perform CPR. Do not underestimate the power of Bystander CPR!
