This article reviews the development of novel reflectance pulse oximetry sensors for the esophagus and bowel, and presents some of the techniques used to analyze the waveforms acquired with such devices.
There has been much research in recent years to expand the utility of pulse oximetry beyond the simple measurement of arterial oxygen saturation from the finger or earlobe. Experimental sensors based on reflectance pulse oximetry have been developed for use in internal sites such as the esophagus and bowel. Analysis of the photoplethysmographic waveforms produced by these sensors is beginning to shed light on some of the potentially useful information hidden in these signals.
The use of novel reflectance pulse oximetry sensors has been successfully demonstrated. Such sensors, combined with the application of more advanced signal processing, will hopefully open new avenues of research leading to the development of new types of pulse oximetry-based monitoring techniques.
本文回顾了用于食管和肠道的新型反射式脉搏血氧饱和度传感器的发展情况，并介绍了一些用于分析通过此类设备获取的波形的技术。
近年来，人们进行了大量研究，以拓展脉搏血氧饱和度测量的应用范围，不再局限于简单地从手指或耳垂测量动脉血氧饱和度。基于反射式脉搏血氧饱和度的实验性传感器已被开发用于食管和肠道等内部部位。对这些传感器产生的光电容积脉搏波波形的分析，开始揭示隐藏在这些信号中的一些潜在有用信息。
新型反射式脉搏血氧饱和度传感器的使用已得到成功验证。此类传感器与更先进的信号处理应用相结合，有望开辟新的研究途径，从而推动新型基于脉搏血氧饱和度的监测技术的发展。
