摘　　要：目的:探讨反射式血氧饱和度无创检测方法。方法:采用扩散传输理论来解释光在组织中的行为,并用此理论对反射式血氧饱和度检测原理进行推导,得出反射式脉搏血氧饱和度检测的计算公式;据此研制出了一种基于MSP430微处理器的反射式血氧饱和度的检测系统,并对该系统进行了全程定标。结果:实验得出了系统的定标结果及定标曲线,并对此进行了分析。结论:给出了利用反射式氧饱和度检测系统测量和计算血氧饱和度的经验公式。Objective To study non-invasive measurement of reflectance oxygen saturation. Methods Diffusion theory was used to explain the action of light in tissue and deduce reflectance oxygen saturation formula. Then, Reflectance Oxygen Saturation Detection System based on MSP430 was developed and calibrated. Result The calibration result and calibration curve was ascertained and analyzed. Conclusion The formula for detection and measurement of oxygen saturation is put forward by using Reflectance Oxygen Saturation Detection System.
