Fibreoptic reflection oximetry allows continuous in-vivo estimation of jugular venous oxygen saturation. In combination with pulse oximetry the oxygen extraction ratio SaO2-SjO2/SaO2 can be derived enabling identification of states of global luxury perfusion, normal coupling of global cerebral blood flow with global cerebral metabolism, global cerebral hypoperfusion and global cerebral ischemia. Several technical difficulties may arise affecting the accuracy of SjO2 recordings which must be recognised by the clinician before medical intervention is contemplated.
光纤反射血氧饱和度测定法可对颈静脉血氧饱和度进行连续的体内评估。结合脉搏血氧饱和度测定法，可得出氧摄取率（SaO2-SjO2/SaO2），从而能够识别全身过度灌注状态、全脑血流量与全脑代谢的正常耦合状态、全脑低灌注状态和全脑缺血状态。可能会出现一些技术难题，影响颈静脉血氧饱和度（SjO2）记录的准确性，临床医生在考虑进行医疗干预之前必须认识到这些问题。
