Cardiopulmonary resuscitation (CPR) is the shortest and most basic of all medical training classes. Most CPR classes take less than four hours to learn the most important medical course you can take. CPR is performed on patients who are not breathing and do not have a pulse. There is no greater emergency. CPR has the effect of getting much-needed oxygen to the brain, where it can keep the nerves of the brain alive long enough for someone to get the patient's heart beating again. http://www.cprcertification-classes.com/
