CAS新生儿NIRS系统可无创测定绝对局部脑组织氧饱和度（SnO2）和脑真静脉氧饱和度（SnvO2）。由于NIR询问的组织包含来自小动脉、小静脉和毛细血管的动脉和静脉血液，因此SnO 2是混合氧饱和度参数，其值介于动脉氧饱和度（SaO 2）和脑静脉氧饱和度（SVO 2）之间。为了确定SnO2的参考值，从脑静脉部位抽取的SvO2与SaO2的相对贡献与全身SaO2的相对贡献约为70：30（SvO2：SaO2）。如果SvO2和SaO2的相对平均贡献的关系是已知的，并且在很大程度上没有变化，则可以使用脉搏血氧仪的SnO2和SaO2无创地确定NIRS真实静脉血氧饱和度SnvO2。
The CAS neonatal NIRS system determines absolute regional brain tissue oxygen saturation (SnO2) and brain true venous oxygen saturation (SnvO2) non-invasively. Since NIRS-interrogated tissue contains both arterial and venous blood from arterioles, venules, and capillaries, SnO2is a mixed oxygen saturation parameter, having values between arterial oxygen saturation (SaO2) and cerebral venous oxygen saturation (SVO2). To determine a reference for SnO2, the relative contribution of SvO2to SaO2drawn from a brain venous site vs. systemic SaO2is approximately 70:30 (SvO2:SaO2). If the relationship of the relative average contribution of SvO2and SaO2is known and does not change to a large degree, then NIRS true venous oxygen saturation, SnvO2, can be determined non-invasively using SnO2along with SaO2from a pulse oximeter.
