Near-infrared spectroscopy systems and methods for monitoring human physiology in activities related to aircraft

A near-infrared spectroscopy (NIRS) system used for monitoring human physiology, the system comprising:

• a substrate;
• a first light source bank capable of emitting a first set of wavelengths of red or near-infrared light, the first light source bank mounted on the substrate;
• a plurality of optical detectors, wherein at least a first optical detector of the plurality of optical detectors is capable of detecting the first set of wavelengths, the plurality of optical detectors mounted on the substrate;
• a processor in electronic communication with at least one of the first light source bank and the optical detector, the processor mounted on the substrate;
• a memory device in electronic communication with the processor, the memory device mounted on the substrate, wherein the memory device is non-transient;
• and
• a battery in electronic communication with at least one of the first light source bank, the optical detector, the processor, and the memory device;
• and
• program instructions stored on the memory device that, when executed, direct the processor to:
• select, based on an input parameter, the first set of wavelengths;
• select, based on the input parameter, the first optical detector of the plurality of optical detectors, the first optical detector being at a first distance from the first light source bank;
• process a first signal from the first optical detector to calculate a first tissue oxygenation level;
• compare the first tissue oxygenation level to a predetermined threshold;
• and
• activate a feedback device when the first tissue oxygenation level is below the predetermined threshold.
