Microcomputer Measurement of Blood and Tissue Oxygenation
Quantitative measurements of blood oxygenation are generally required in studies of oxygen transport to tissue, but oximeters and similar blood oxygen-measuring devices are usually single-purpose instruments incapable of making other measurements. Moreover, they do not provide the continuous, on-line measurements necessary to explore the dynamics of tissue oxygenation. The advent of the microcomputer has made it possible to overcome these limitations.
