The present invention relates generally to in vivo physiological sensors, and more particularly to physiological sensors utilizing optical fibers (102a,b) and capable of measuring a plurality of serum analytes. By using 2 optical fiber sensors (101a) and (101b), one sensor to measure ionic species (101a) and another sensor for measuring gaseous species (101b), a greatly increased number of analytes can be monitored, as compared with prior art, by a single sensor while providing a physiological sensor of small diameter since only two optical fibers (102a,b) are necessary. |
