摘　　要：利用近红外光谱技术的无创血氧测量得到了广泛应用。分析了传统的双波长光源测量低血氧的误差原因,采用三波长测量算法提高了测量精度。定标实验证明了文中选取的三波长光源的准确性。通过对系统性能的测试比较,得出该系统具有较高的准确度和较好的实时性。此系统在低血氧饱和度监护方面具有广泛的应用前景。The method that noninvasively measures blood oxygen with near-infrared spectroscopy is widely used. The error reason that measures bow blood oxygen saturatio with conventional two-wavelength light, measure precision was improved with three-wavelength method. The calibration experimental results showed that the three-wavelength is accurate. Through comparison of system performance test,it showed that the syetem hod high accuracy and good real-time. The system has a wide application in low oxygen staturation monitoring.
