Abstract
A control apparatus is described which can be incorporated into conventional intermittent positive breathing gas pressure lung treatment systems to provide for holding the gas in the lungs for a brief period of time after inspiration and before expiration. The control apparatus in the system delays the opening of a gas pressure release opening exhaust valve associated with the patient breathing portion of the system. The apparatus enables such systems to more closely simulate normal breathing and to increase the time during which vaporized medication supplied in the breathing gas can be absorbed in the lungs.
