阻抗呼吸监测系统在多参数监护仪中的应用

摘要

This paper introduces a breath monitoring system by the thorax impedance change. This system can get the breath number and wave on the oscillograph that monitors and enlarges the thorax impedance change by detection and amplification of drive signal . It is valuable for serious patient used in the multi-parameter monitor.%本文介绍一种利用胸阻抗变化来进行呼吸监测的系统,该系统通过随胸阻抗变化激励信号的检测和放大等,获得可以在示波器上显示出来的呼吸信号波形及计算呼吸次数等,临床多参数监护仪使用该系统对危重病人的监护有较高的实际价值.
