CPR stands for cardiopulmonary resuscitation. It is an emergency life-saving procedure that is done when someone's breathing or heartbeat has stopped.
At the class we learnt the three basic parts of CPR which are easily remembered as "CAB": “C” for compressions, “A” for airway, and “B” for breathing. C is for compressions; chest compressions can help the flow of blood to the heart, brain, and other organs. A is for airway & B is for breathing. We learnt the hands-only CPR i.e. call emergency number and push hard and fast on the chest.
