| 摘 要： | 根据呼吸对心冲击信号的调制作用，提出一种基于坐姿心冲击信号的呼吸率实对检测方法。通过分析不同呼吸状态下心冲击信号的时域振幅及频域成分的变化，确定了呼吸对心冲击成分的调制作用，并采用改进的J波检测算法定位实测信号中的W形组合波，对J波和K波进行重新采样，最终使用平滑滤波器恢复呼吸波形，并计算曲呼吸率。为了验证算法的可行性和准确性，应用小波分析方法进行定性对比实验，并同步采集鼻热敏呼吸信号进行定量统计。实验结果表明，所提方法可以从心冲击信号中较为准确的检测出呼吸率，为多生理参数的无感觉同步监测做了有益的尝试。

| Abstract: | Based on the fact that the respiratory component modulated the ballistocardiogram signal,a method was proposed which detected respiratory rate real-time from the sitting ballistocardiograph signal.Through analyzing the change of time-domain amplitude and spectrum of BCG signal under different respiration statuses,the modulation effect was determined.Then the W complex component of measured signal was located with improved adaptive J wave detection algorithm,the J and K wave was resampled,the time-domain wav... |
