1. A pulse oximeter attachment comprising:

  • a first path adapted to communicate an LED drive current from a first stand alone instrument;

    a second path adapted to communicate a waveform, from a second stand alone instrument, responsive to said LED drive current to said first stand alone instrument; and

    a memory device storing information;

    at least a portion of said information stored in said memory device representative of calibration information;

    said portion of said information readable from said memory device so as to enable said first stand alone instrument to calculate and display an accurate oxygen saturation value based on information obtained using the second stand alone instrument.
