Abstract
A novel respiratory gas analyzer employs optical fibers to facilitate in-stream, multiple component infrared analysis. In one embodiment, the analyzer (10) includes an infrared source (12), entrance optics (14), a sample chamber (20), exit optics (24) and a detector assembly (28). One or both of the entrance optics (14) and exit optics (24) includes infrared optical fibers. In this manner, the source (12) and or detector assembly (28) can be located away from the patient (22) as may be desired. In addition, the fiber optic implementation reduces system complexity and optical alignment concerns.
