Abstract:
A method for calibrating a non-invasive blood constituent monitor connected to a traditional measurement system via a data link, the non-invasive monitor having an analyzer window, the method comprising:determining whether there is a restricted period in effect; selecting a first measurement location distal of a wrist or a second measurement location other than distal of the wrist based on whether a restricted period is in effect; performing a traditional measurement of a blood constituent at the selected measurement location using the traditional measurement system; generating a traditional monitor output representing a property of the blood constituent; placing the analyzer window of the non-invasive blood constituent monitor in contact with the skin of a patient; analyzing the blood constituent in blood within the patient with the non-invasive blood constituent monitor; generating a non-invasive monitor output representing the property of the blood constituent; comparing the traditional monitor output and the non-invasive monitor output to estimate an error; and correcting the non-invasive monitor output based on said error.
