1. A method for performing a pulse oximetry, the method comprising:

  • emitting a light signal for a period of time;

    detecting a modulated light signal, the modulated light signal including a red signal and an infrared signal originating from an interaction of the light signal with a human tissue, the human tissue including a pulsatile tissue and a non-pulsatile tissue; and

    processing the modulated light signal to estimate at least an oxygen saturation in the pulsatile tissue during the period of time, wherein the processing includes at least removing a non-pulsatile component resulting from the interaction of the light signal with the non-pulsatile tissue.
