Fiber-Optic Absorptive Oximeter

In this paper the model of the absorptive fiber-optic oximeter with specially designed fiber-optic head coupled to two light-emitting diodes and a photodiode is presented. We constructed the blood chamber allowing the tips of optical fibers to be in contact with the blood under measurements. The absorptive fiber-optic oximeter was clinically tested in Central Hospital for Children in Warsaw. Results obtained were compared with the oxygen saturation measured by the classical oximeter OSM2 Hemoximeter.
