Summary:An apparatus and a method for non-invasively determining the blood oxygen saturation within a subject's tissue by near-infrared spectroscopy use the multi-distance method and take into account the attenuation of the light signal due to light absorbers other than hemoglobin and deoxyhemoglobin and the scattering properties of a subject's tissue. The apparatus and the method are particularly adaptedfor the measurement of blood oxygen saturation in the abdomen of newborns taking into account meconium, transitional stool and biliverdin. 本发明涉及用于通过近红外光谱法使用多距离方法非侵入性地确定受试者的组织内的血氧饱和度并考虑由于除了血红蛋白和脱氧血红蛋白以外的光吸收剂和受试者的组织的散射特性导致的光信号的衰减的装置和方法。
