The technology near infrared spectroscopy (NIRS) has been utilized extensively in several clinical settings and one of which is in cerebral oximetry. This review will provide information on the technology, clinical applications and algorithm to follow when desaturation occurs.
The review will cover the technology of near infrared spectroscopy, cerebral oximetry and the utilization of cerebral oximetry in each clinical setting. Expert commentary: Cerebral oximetry provides a noninvasive measure of cerebral oxygenation, which when persistently declining, can serve as a warning sign of hemodynamic or metabolic compromise intraoperatively or a predictor of postoperative cognitive dysfunction. Although useful, the cerebral oximetry readings must be interpreted in the context of other clinical information. When cerebral desaturation is confirmed, an algorithm should be followed in an attempt to increase oxygen delivery to the brain and/or decrease cerebral metabolic rate of oxygen.
近红外光谱技术（NIRS）已在多种临床环境中广泛应用，其中之一是用于脑血氧饱和度测定。本综述将提供有关该技术、临床应用以及发生血氧饱和度降低时应遵循的算法的信息。
本综述将涵盖近红外光谱技术、脑血氧饱和度测定以及脑血氧饱和度测定在每种临床环境中的应用。专家评论：脑血氧饱和度测定提供了一种无创的脑氧合测量方法，当脑氧合持续下降时，可作为术中血流动力学或代谢受损的警示信号，或术后认知功能障碍的预测指标。尽管脑血氧饱和度测定很有用，但必须结合其他临床信息来解读其读数。当确认脑血氧饱和度降低时，应遵循一种算法，试图增加向大脑的氧输送和/或降低大脑的氧代谢率。
