Pulse oximetry monitoring is a relatively recent technique that has been embraced enthusiastically by medical, nursing and paramedical personnel in many clinical situations. Few people, however, have any idea of how it provides the reading of arterial blood saturation. This review performs several functions: it discusses the haemoglobin molecular structure and explains its relation to spectrophotometry, describes the history and principles of pulse oximetry and the nature of the equipment used, and reviews its common uses. It also explores the principles and proposed uses of its lesser known corollary, photoplethysmography.
脉搏血氧饱和度监测是一项相对较新的技术，在许多临床情况下受到了医学、护理和辅助医疗人员的热烈欢迎。然而，很少有人知道它是如何提供动脉血氧饱和度读数的。这篇综述有几个作用：它讨论了血红蛋白的分子结构并解释了其与分光光度法的关系，描述了脉搏血氧饱和度监测的历史和原理以及所用设备的性质，并综述了其常见用途。它还探讨了其鲜为人知的推论——光电容积描记法的原理和建议用途。
