Artificial ventilation

Artificial ventilation, also called artificial respiration, is a means of assisting or stimulating respiration. Respiration is the overall metabolic process that exchanges gases in the body through pulmonary ventilation, external respiration, and internal respiration. Artificial ventilation may take the form of manually providing air for a person who is not breathing or is not making sufficient respiratory effort, or it may take the form of mechanical ventilation involving the use of a ventilator to move air in and out of the lungs when an individual is unable to breathe on their own, such as during surgery with general anesthesia or when an individual is in a coma or trauma.
