Abstract
The onset of hypoxia symptoms in warfighters during ground operations at high altitude and casualties during CASEVAC can go unrecognized and have catastrophic consequences. There is a need to provide timely warnings and mitigations by detecting physiological and environmental changes that can predict the onset a hypoxic state. Hypoxia can be caused by many external stressors individually and in combination, including altitude, physical work load, cognitive work load, dehydration, disorientation, breathing gas mixtures, protective garments and other environmental conditions. The detection/prediction of hypoxia requires not only the sensing of such external stressors but also the individual s physiologic responses including respiratory functions, cardiac parameters, blood and tissue oxygen levels, and changes in the individual s tolerance and accommodation from day to day. In general, a single parameter, whether an external stressor or a physiological response cannot provide a robust determination of an individual s state with respect to onset or presence of hypoxia. This task requires the sensing of many stressors and responses, evaluating their meaning, and fusing the results to get the best measure of the state. Furthermore, the sensor data collection, fusion and Hypoxia/No Hypoxia decision making should be preferably performed in real time.
