The Nursing Station – CPR can save a person who just suffered cardiac arrest by helping the blood circulation through the vital parts of the body.  Pumping the heart through systematic rhythmic thrusts or chest compressions help the heart contract, forcing blood to go through the blood stream.  This would enable the blood to circulate and reach all major organs of the body, particularly the brain.  It is vitally important for the brain not to lose oxygen, which can occur during cardio-pulmonary arrest.  Proper CPR skills learned through correct CPR instruction oxygen can be delivered to an unconscious person who is not breathing, lessening the risk of brain damage. CPR training can help train you to perform proper CPR techniques that can help you save a person’s life.
