METHOD FOR NON-INVASIVE ASSESSMENT OF BLOOD OXYGENATION LEVEL

摘要

A method for non-invasive assessment of the level of blood oxygenation provides for illuminating the tissue with the light beam followed by recording the intensity of the reflected light in bright-red and dark-red spectral ranges corresponding to the blood flows containing oxyhemoglobin and deoxyhemoglobin. N fingers (N2) are assayed. The level of blood oxygenation is assessed according to the intensity of the reflected light in bright-red and dark-red spectral ranges.
