Cardiopulmonary resuscitation (CPR) is a combination of rescue breathing and chest compressions delivered to victims thought to be in cardiac arrest.
Heart stops pumping blood, when there is a cardiac arrest , which is often caused by an abnormal heart rhythm called ventricular fibrillation (VF).CPR can support a small amount of blood flow to the heart and brain to “buy time” until normal heart function is restored.
If you learn the signs of a heart attack and what steps to take, you can save a life–maybe your own.
A heart attack (also called myocardial infarction) is when part of the heart muscle is damaged or dies because it isn’t receiving oxygen. Oxygen is carried to the heart by the arteries (blood vessels). Most heart attacks are caused by a blockage in these arteries. Usually the blockage is caused by atherosclerosis, which is the buildup of fatty deposits (called plaque) inside the artery.
