Realtime physiological performance monitoring to prevent fatigue in special forces soldiers

A proof of concept performance monitoring system was designed to allow for the realtime assessment of the physiological exertion of Special Forces soldiers during combat. The system was designed to be integrated into the Tactical Assault Light Operator Suit being developed the United States Special Operations Command. It consisted of a suite of sensors integrated into a headset that measures heart rate, respiratory rate, and end tidal CO₂. The data was presented as a color-coded scale with different colors representing increasing levels of exertion. The prototype was then tested to ensure that it met its design criteria.
