1. A method of calibrating a pulse oximeter comprising:

  • selecting a probe having an emitter, a detector, and a pathlength between the emitter and detector;

    measuring transmission of light through a tissue of interest with the probe;

    compiling a database of measured values characterizing the transmission of light through such a tissue;

    formulating a value for a parameter kDC as a function of at least one of the measured values; and

    incorporating the parameter kDC into a calibration equation for determining a value for SpO2.
