1. A physiological monitor for determining blood oxygen saturation of a medical patient, comprising:

  • a sensor, wherein said sensor comprises at least three light emitting diodes, each light emitting diode adapted to emit light of a different wavelength and a detector, wherein said detector is adapted to receive light from said at least three light emitting diodes after being attenuated by tissue, and wherein said detector generates an output signal based at least in part upon said received light;

    a signal processor, wherein said signal processor determines blood oxygen saturation based at least upon said output signal; and

    a display, wherein said display provides an indication of said blood oxygen saturation.
