摘　　要：血氧饱和度是人体的重要参数,临床上许多场合都要对血氧饱和度进行检测。透射式血氧饱和度检测法已经成为一种比较成熟的检测手段,它可以实时、连续和无创伤地进行血氧饱和度检测。本文首先对透射式血氧饱和度检测法的原理进行了详细分析,接着对透射式血压饱和度检测系统的设计进行了阐述,最后指出了目前透射式血氧饱和度检测中仍存在的不足之处以及未来的发展趋势。Oxygen saturation is one of the important parameters of human body. The measurement of oxygen saturation is applied widely in clinical diagnosis. Transmittance oximetry is well developed as a monitoring technique. With it, oxygen saturation can be monitored timely, continuously and non-invasively. This paper mainly analyzed the measuring principle of transmittance oximetry, The design of the monitoring system is also discussed then. At last, the paper pointed out the shortcoming of the transmittance oximetry and its trend of development.
