研制了一种采用单片机控制的阻抗式呼吸监护系统，它与心电监护共用一对电极，可作为心电呼吸监护仪的一个子功能模块，同时它也可以独立工作。该阻抗式监护系统对心电、肌电等外界干扰有较好的抑制作用，获得的呼吸波形，稳定性好。具有较大的临床应用价值。“,”This paper introduces an impedance pneumograph monitor based on the single chip computer 80C552. It shares the same pair electrodes with ECG, and not only be applied to a multi-parameter physiological monitor as a subfunction model, but also can be operated as an independent instrument. This impedance pneumograph monitor can retrain the external interference such as ECG and myoelectricity with high efficiency, and has the advantages of smooth tespiratory waveform, good stability and high clinical application value.
