1. A method for communicating a physiological waveform indicative of a physiological condition to a patient monitoring device, the method comprising:

  • obtaining a sensor signal indicative of a physiological parameter;

    calculating a first physiological measurement using a first processor;

    communicating the physiological measurement to a second processor;

    outputting a physiological sensor signal from the second processor based on the calculated first physiological measurement; and

    communicating the outputted physiological sensor signal to a patient monitoring device not associated with the first and second processors, the outputted physiological sensor signal configured to cause the patient monitoring device to calculate a second physiological measurement substantially equivalent to the first physiological measurement.
