1. A method for determining oxygen saturation, the method comprising:

  • determining a first oxygen saturation value based upon signals received from a patient using a first saturation calculation algorithm;

    determining a second oxygen saturation value based upon signals received from the patient using a second saturation calculation algorithm; and

    arbitrating between the first and second oxygen saturation values based on a saturation confidence associated with the first and second oxygen saturation values to determine a final oxygen saturation value based on the first oxygen saturation value and the second oxygen saturation value.
