A wearable oximeter is needed to help people safely perform missions in environmental extremes. Key initial needs are to monitor for hypoxia a thigh altitudes, and to monitor for shock and hemorrhage during trauma. An initial investigation has been performed to assess design parameters for a wearable oximeter. Initial data was collected to assess the forehead, manubrium, and xiphoid process as wear locations to assess required power and to characterizethe types and significance of motion artifacts that will need to be mitigated. The forehead was confirmed to bean excellent site with respect to signal quality, but signal corruption from changes in contact pressure will need to be mitigated. The sternal locations are initially assessed to be be more challenging, likely requiring more power and site-specific motion artifact mitigation.
