FREE Class Compression Only CPR, also known as Hands Only CPR, keeps oxygen-rich blood circulating to vital organs until EMS personnel arrive or an automated external defibrillator (AED) is applied to shock the heart. A victim of cardiac arrest is 3 times more likely to survive with COCPR. Participants will have the opportunity to practice compressions on adult manikins. Choking and abdominal thrusts, use of an AED, COCPR for children, and COCPR for infants will also be reviewed.
