消除呼吸阻抗测量时运动干扰方法中关键参数的选取初探

Preliminary Study on Select Value of Important Parameter of Method to Reduce Motion Artifacts in Monitoring Respiration Using Impedance Measuring Technology

双频率阻抗测试和自适应处理技术相结合消除呼吸阻抗测量中运动干扰的方法是一种较简单且实用的方法，本文对该方法中关键参数的选取进行了实验研究，得出了该参数的变化趋势。

The method of using two frequency impedance pneumography and adaptive filter to reduce motion artifacts in monitoring respiration is not only simple but also practical. The value of an important parameter is decisive factor in using this method to gain good results. The changing tendency of the parameter was found by doing human experiments and the results were presented in this paper.
