Claim Text:
1. A method for non-invasively determining a blood oxygen parameter value of a subject's tissue, comprising: providing a spectrophotometric sensor having one or more transducers, each operable to transmit light into the subject's tissue and to sense the light after passage through the subject's tissue, and a processor portion adapted to selectively control transmission of light by each transducer and to receive and process signals from each transducer, which signals are representative of the sensed light; transmitting light into the subject's tissue using the sensor; detecting light after passage through the subject's tissue using the sensor, and producing initial signal data from the light sensed; calibrating the sensor, using the processing portion, to that particular subject using the initial signal data, thereby accounting for the specific physical characteristics of the particular subject's tissue being sensed; and determining the blood oxygen parameter value within the subject's tissue using the calibrated sensor.
