Giving CPR can be damaging. Ideally the heart is not meant to be "massaged" through the rib cage. There is a chance that you will break ribs during CPR. However, you must keep in mind that if you need to do CPR, the person is dead. ANYTHING you do can possibly help. Even though you may break a rib or two, it's better than watching someone die.
