Cardiopulmonary resuscitation (CPR) is an important step in the chain of survival during a cardiovascular emergency. CPR is a valuable, potentially life-saving skill and certification. People as young as 7 years of age can obtain a CPR certification as long as they can pass the written test and demonstrate the physical skills required for CPR certification. If you want to become part of the "chain of survival" you can locate a CPR course in your neighborhood by visiting the American Heart Association or Red Cross Web sites.
