A device used for the artificial ventilation of a person who is unable to breathe naturally. A ventilator is an electrical pump connected to an air supply that works like bellows. Air is directed through a tube passed down the windpipe to inflate the lungs. The air is then expelled by the natural elasticity of the lungs and ribcage. A valve on the ventilator prevents the expelled air from re-entering the lungs.
