Non-invasive method and apparatus for monitoring hemoglobin concentration and oxygen saturation |
| abstract |
(57) [Problem] To provide a method and an apparatus for monitoring non-invasive hemoglobin concentration and oxygen saturation. SOLUTION: Step 10 of selecting at least two wavelengths including at least two isobestic wavelengths from wavelengths belonging to a wavelength band whose extinction coefficient of water is lower than that of hemoglobin, and incident light having the selected wavelength. Sequentially irradiating a predetermined part including a blood vessel of the body with Receiving light sequentially transmitted through a predetermined portion at a single point on the body, and converting the received light into an electric signal. 4, 16; a step 18 of obtaining a change in light attenuation due to an arterial wave for each wavelength from an electrical signal; a step 20 of obtaining at least one ratio between the changes; and at least one ratio included in blood. Calculating the hemoglobin concentration. Also, the method includes a step 24 of measuring the oxygen saturation more accurately than before in consideration of the concentration of hemoglobin. |
