A new method to estimate arterial oxygen saturation is suggested based on the presence of the plethysmographic pulse. A prototype skin reflectance oximeter system utilizing a miniature solid state optical transducer has been constructed. Preliminary data collected from a group of volunteers indicated good quantitative correlation between skin reflectance and arterial oxygen saturation as determined by an earlobe oximeter. We are now investigating the dependency of the measurements on various physiological conditions and skin characteristics in order to determine appropriate calibration procedures. This study has demonstrated for the first time that arterial hemoglobin oxygen saturation can be measured quantitatively using transcutaneous reflectance techniques. However, more extensive work is needed to further develop this technique into a viable clinical tool.
基于体积描记脉搏的存在，提出了一种估计动脉血氧饱和度的新方法。利用微型固态光学传感器构建了一个原型皮肤反射式血氧计系统。从一组志愿者收集的初步数据表明，皮肤反射率与通过耳垂血氧计测定的动脉血氧饱和度之间存在良好的定量相关性。我们现在正在研究测量结果对各种生理条件和皮肤特征的依赖性，以确定合适的校准程序。这项研究首次证明，可以使用经皮反射技术定量测量动脉血红蛋白氧饱和度。然而，需要开展更广泛的工作，以将这项技术进一步发展成为一种可行的临床工具。
