1. A patient sensor device, comprising:

  • an emitter configured to emit light into a tissue of a patient;

    a detector configured to detect the light from the tissue of the patient and produce a corresponding electrical signal;

    signal processing circuitry configured to receive and convert the electrical signal of the detector into detector signal data;

    a wireless module communicatively coupled to a patient monitor and configured to transmit a physiological parameter value, the detector signal data, or both, to the patient monitor; and

    a processor configured to;

    determine whether the patient sensor or the patient monitor should calculate the physiological parameter value based, at least in part, on the detector signal data;

    calculate the physiological parameter value for the patient based, at least in part, on the detector signal data, if the processor determines that the patient sensor should calculate the physiological parameter value; and

    send the detector signal data to the patient monitor, via the wireless module, to calculate the physiological parameter value for the patient based, at least in part, on the detector signal data, if the processor determines that the patient monitor should calculate the physiological parameter value.
