Assistance takes many forms, but generally entails providing air for a person who is not breathing or is not making sufficient respiratory effort on his / her own . It is used on a patient with a beating heart or as part of cardiopulmonary resuscitation (CPR) to achieve the internal respiration). </P> <P> Pulmonary anton ventilation (and hence external parts of respiration) is achieved through manual insufflation of the lungs either by the rescuer blowing into the patient's lungs, or by using a mechanical device to do so .

It is also known as expired air resuscitation (EAR), expired air ventilation (EAV), rescue breathing or colloquially the kiss of life . It was introduced as a life saving measure in 1950 . </P>
