Near-infrared spectroscopy (NIRS) is a technique that can be used as a noninvasive and continuous monitor of the balance between cerebral oxygen delivery and consumption. The authors develop and propose an algorithm for the use of NIRS based on optimizing factors that can affect cerebral oxygen supply/demand. These factors are the position of the vascular cannula, perfusion pressure, arterial oxygen content, partial pressure of carbon dioxide, haemoglobin, cardiac output, and the cerebral metabolic rate of oxygen. Dissemination of a useful treatment algorithm is the primary purpose of this article. Further multicenter studies are necessary to confirm the benefits and cost-effectiveness of this promising monitoring modality.
近红外光谱技术（NIRS）是一种可用于对脑氧输送与消耗之间平衡进行无创且连续监测的技术。作者基于优化影响脑氧供需的因素，开发并提出了一种使用NIRS的算法。这些因素包括血管插管位置、灌注压、动脉血氧含量、二氧化碳分压、血红蛋白、心输出量以及脑氧代谢率。传播一种实用的治疗算法是本文的主要目的。有必要开展进一步的多中心研究，以证实这种前景广阔的监测方式的益处和成本效益。
