CPR
CPR stands for cardiopulmonary resuscitation Cardio is a medical word for heard Pulmonary is a medical word for lungs. Resuscitate means to bring back to life. CPR starts someone's lungs and heart functioning again after they have stopped It is an amazing idea there is a cure for sudden death. It is equally amazing that that this magic is not done by today's high technology. Any ordinary person can do it. You use your own lungs to breathe into the patient's mouth and start his or her lungs working. You push on the heart with your hands to make it start beating again. It is as easy as that. The heart is a large muscle that pumps blood through the arteries. It is located in the center of the chest behind the breastbone. The lungs are at either side of the heart Air enters the nose and mouth and moves through the airway to the lungs, bringing oxygen into the body. As the blood moves to the lungs, it picks up the oxygen and carries it to the cells throughout the body. At the same time that the blood picks up the oxygen, it leaves carbon dioxide as a waste material, and the lungs breathe it out through the airway When the heart stops beating, or a person stops breathing, this whole process stops. No oxygen is taken into the body, and the blood doesn't move through the arteries CPR can start the process moving again There are several situations when CPR is needed. It can be used when a person has a heart attack and the heart stops. A heart attack occurs when the heart cannot get enough oxygen. This usually happens because one of the two arteries to the heart has become narrow or completely blocked. The heart muscle cells that are supplied with oxygen by that artery die because they stop receiving oxygen. of the symptoms ofa heart attack is a feeling of pressure and tightness or aching in the center of the chest. It lasts longer than 2 minutes, and it may come and go. The person a heart attack may also start sweating, feel weak, be short of breath, and feel like vomiting. However, there may be no symptoms at all; the heart may stop suddenly, and the person may stop breathing. If CPR is started immediately it may bring the person back to life
