Abstract
PURPOSE:To enable the direct and continuous measurement of the fluctuation in the content of hemoglobin (Hb) in blood by an optical technique from a living body by selecting the specific two different wavelengths at which only the change in the absorbancy by Hb is substantially changed in a >=700nm wavelength region. CONSTITUTION:The specific two different wavelengths at which only the change in the absorbancy by the Hb is substantially generated in the >=700nm wavelength region are selected and the light rays of these wavelengths are directly projected to the biotissue. The measurement is then made in accordance with the changes DELTAA1 and DELTAA2 in the absorbancy with the respective wavelengths, K1; the absorption coefft. of the oxidation type Hb at the wavelength lambda1, K1'; the absorption coefft. of the deoxidation type Hb at the wavelength lambda1, K2; the absorption coefft. of the oxidation type Hb at the wavelength lambda2, K2'; the absorption coefft. of the deoxidation type Hb at the wavelength lambda2. Namely, the fluctuation in the respective quantities of the oxidation type Hb and the deoxidation type Hb and/or the fluctuation in the total Hb quantity in the optical path for irradiation is directly and continuously measured.
