Sudden cardiac arrests can be treated by administering Cardiopulmonary Resuscitation (CPR) to the victim, aiming to get his heart working again. The goal of CPR is to renew the circulation of blood. This is done by compressing the victim's chest to press the heart between the ribs, and at the same time breathing into the victim's mouth to force oxygen into his mouth. CPR is a technique which is performed as an emergency and temporary measure to fill the organs with oxygen until heart function is restored. Research says that only about 15% of victims who get CPR are survivors.
