what is the purpose of mouth to mouth resuscitation
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.[1][2] 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.[3] It is used on a patient with a beating heart or as part of cardiopulmonary resuscitation (CPR) to achieve the internal respiration).
Larynx The larynx (/ˈlærɪŋks/; plural larynges; from the Greek λάρυγξ lárynx),[1] commonly called the voice box, is an organ in the neck of tetrapods involved in breathing, sound production, and protecting the trachea against food aspiration. The larynx houses the vocal cords, and manipulates pitch and volume, which is essential for phonation. They are situated just below where the tract of the pharynx splits into the trachea and the esophagus.
