REDUCED-OXYGEN BREATHING DEVICE |
摘要 |
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, thereby simulating selected altitudes 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 low when compared to re-breathing 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 subject. |
