1. A method for measuring blood oxygen saturation comprising:

  • emitting light from at least one light source;

    detecting a plurality of light spectrums having time-varying components from the light with at least one detector subsequent to the light being scattered by tissue, the plurality of light spectrums including a first light spectrum having a wavelength between 725 and 745 nanometers and a second light spectrum having a wavelength between 880 and 940 nanometers; and

    calculating a blood oxygen saturation reading using a pulse oximetry algorithm based on the plurality of detected light spectrums.
