Mouth-to-mouth resuscitation

Mouth-to-mouth resuscitation, a form of artificial ventilation, is the act of assisting or stimulating respiration, a metabolic process referring to the overall exchange of gases in the body, where a rescuer presses his or her mouth against that of the victim and blows air into the person's lungs. 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).
