1. A measurement device comprising:

  • a measurement module configured to obtain noninvasive physiological parameter measurements from a sensor coupled with a patient; and

    a calibration module comprising a processor configured to;

    receive an alternative physiological parameter measurement at the noninvasive device,output a first trend graph of the noninvasive physiological parameter measurements for display,output a second trend graph that reflects a difference between the noninvasive physiological parameter measurements and the alternative physiological parameter measurement;

    determine an offset value based at least in part on the difference between the noninvasive physiological parameter measurements and the alternative physiological parameter measurement;

    calibrate the noninvasive device based at least in part on the offset value;

    track an age of the offset value over time;

    provide a user interface control on the noninvasive device, the user interface control configured to provide functionality for a user to input the offset value into the noninvasive device, the user interface control further configured to provide functionality for the user to modify the offset value over time;

    display the offset value on a user display of the noninvasive device; and

    display an indication of the age of the offset value on the user display.
