双通道呼吸阻抗测量系统的研制

The Development of a Two-channel Impedance Pneumography

为了能够得到高低两种不同频率下的呼吸阻抗信号，设计研制了一套高性能的双通道呼吸阻抗测量硬件系统，编制了用于实时采集数据、显示波形、存储数据的软件系统。详细介绍了此测量系统的硬件和软件设计，并通过人体实验证实了此测量系统反映灵敏、测量准确。

To obtain respiratory signals with impedance method at two measuring frequencies, a high-performance two-channel impedance pneumography was implemented and the software including acquisiting data,showing waves,storing datas were developed.Human experiment was done and the results were also presented.
