Warren County Health Services is recommending those who have the capability to do so to be trained in how to perform CPR. According to the American Red Cross, about 47% of sudden cardiac deaths occur outside a hospital. CPR is a lifesaving procedure that is performed after someone suffers sudden cardiac arrest, which is different from a heart attack, and includes a combination of rescue breathing and chest compressions, which serve to deliver oxygen to a person’s lungs and help circulate the blood and help keep the victim alive until medical personnel can take over.
