Abstract
Disclosed is an apparatus for measuring a predetermined data of a living tissue, such as an oxygen saturation, a dye dilution curve and level of hemoglobin. The apparatus has an illumination intensity computing and storing circuit that stores the intensities of light components emitted from a three-wavelength light source assembly, and a computing circuit that calculates the intensity ratios of illuminating light from the intensity data stored in the circuit. The circuit determines the predetermined data of blood on the basis of the calculated intensity ratios and the intensities of light transmitted through a living tissue under assay, and it displays the predetermined data on display unit. The apparatus is capable of measuring the predetermined data without relying upon pulsations that occur in the subject.
