Patent application Serial Number 60/318827 entitled “A Device to Mix and Administer a Mixture of Nitrogen and Oxygen to Create a Continuously Variable Gas Mixture” filed September 14, 2001. The present invention includes a non-rebreathing circuit coupled with computer-controlled gas adjustments. Ambient air is diluted with nitrogen on a breath-by-breath basis to provide precise control over the inspired concentration of oxygen/nitrogen mixture of simulated altitude air on an almost instantaneous basis. Carbon dioxide and water vapor exhaled by the subject are released into the environment, and absorption is not necessary. In addition, the mixed gas can be administered through a standard aviator's oxygen mask, increasing the realism of the simulation and removing obvious external cues on the nature of the experiment. Maintenance on the mixing loop is lower compared to rebreathing units, since no consumable items are necessary to absorb water vapor or carbon dioxide. A mixing device provides a homogenized mixture of nitrogen/oxygen fluid to the user.


Applications for an exclusive or partially exclusive license may be submitted at any time from the date of this notice.
