<unk> , a form of artificial ventilation, is the act of assisting or stimulating respiration in which a rescuer presses their<unk>  against that of the victim and blows air into the person's lungs. Artificial respiration takes many forms, but generally entails providing air for a person who is not breathing or is not making sufficient respiratory effort on their own. It is used on a patient with a beating heart or as part of cardiopulmonary<unk>  (CPR) to achieve the internal respiration. Pulmonary ventilation (and hence external 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. This method of insufflation has been proved more effective than methods which involve mechanical manipulation of the patient's chest or arms, such as the Silvester method. It is also known as expired air<unk>  (EAR), expired air ventilation (EAV), rescue breathing, or colloquially the kiss of life. It was introduced as a life saving measure in 1950.<unk>  is a part of most protocols for performing cardiopulmonary<unk>  (CPR) making it an essential skill for first aid. In some situations,<unk>  is also performed separately, for instance in near-drowning and opiate overdoses. The performance of<unk>  on its own is now limited in most protocols to health professionals, whereas lay first-aiders are advised to undertake full CPR in any case where the patient is not breathing sufficiently.
