Cardiopulmonary resuscitation (better known as CPR) is a lifesaving manual technique that pumps oxygenated blood back into the body’s organs if someone’s heart or breathing has stopped. A variety of CPR training is available to community members, employees and healthcare providers. CPR training may last two to five hours or more, depending on the content and the target audience. During the training, students will learn how to recognize and respond to an emergency situation. There are different CPR techniques for adults and children, but with both you will learn how to determine whether the person is conscious before administering chest compression. During the training you’ll learn chest compression techniques for adults and different techniques for children between the ages of 1 and 8. Students learn how to properly administer chest compressions, when the technique is appropriate and when it is not, and how long you must perform rescue measures. Students also learn what an automatic external defibrillator (AED) is and how to use it if necessary to shock a patient before administering CPR chest compressions.
