Hypoxia is a dangerous condition for naval aviators that impacts critical thinking, resulting in a lack of awareness that prevents aircrew from taking appropriate corrective actions. Practical hypoxia training allows pilots to experience the effects of hypoxia so that the symptoms are more readily recognized. Current training systems include both hypobaric chambers and reduced oxygen breathing systems that require multiple compressed gas cylinders for operation. To meet the Navy s need for a truly portable and convenient hypoxia training system, we propose to develop a new hypoxia training system based on modern gas separation technology that will abrogate the need for compressed gas cylinders and only require electrical power. Our system involves a simple, safe control scheme that places a physical limit on the lowest oxygen concentration that can be delivered. The system will also feature advanced physiological monitoring capabilities. In Phase I, we will develop a benchtop version of the system and demonstrate its performance using a breathing simulator. In Phase II, we will develop a highly integrated, compact version of the system and demonstrate it with humans. Creare is partnered with a leading supplier of aviation oxygen equipment to ensure that the technology is smoothly transitioned to the Navy.
