Birth and death are the two natural phenomena that all of us have to accept. When a child is born we are happy because a new person is added to our company, where as, when someone dies, we grieve because he/she is no more with us. Death can occur at any time due to any cause. However death in certain instances can be prevented. For instance death due to cardiac arrest can be prevented by giving cardio pulmonary resuscitation in time. Cardio pulmonary resuscitation is a technique used in cardiac arrest to establish heart and lung function until more advanced life support is available.Resuscitation was attempted in the past through various methods e.g. slapping victims, making loud noises. The mouth –to mouth method was reported prior to 1950 but it has now become the most preferred method. At first only medically trained personnel were allowed to perform CPR, since chest compression could produce internal injuries. Kouwenhoven and his colleagues set a new land mark for effective external cardiac compression, coupled with mouth to mouth breathing in the resuscitation of victim who had total circulatory stand till. As a result, the combination of closed – chest cardiac massage and mouth-to-mouth rescuer breathing, coupled with the introduction of external defibrillation, created cardio pulmonary, resuscitations as it is known today. Thus the foundation of modern CPR was laid in 1960
