METHOD FOR SPECTROPHOTOMETRIC BLOOD OXYGENATION MONITORING |
摘要 |
According to the present invention, a method and apparatus for non-invasively determining the blood oxygen saturation level within a subject's tissue is provided. The method comprises the steps of: a) providing a spectrophotometric sensor operable to transmit light into the subject's tissue, and to sense the light; b) detecting light after passage through the subject's tissue using the sensor, and producing initial signal data from the light sensed; c) calibrating the sensor 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 d) using the calibrated sensor to determine the blood oxygen parameter value within the subject's tissue. |

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. |
