摘　　要：呼吸是人体的一个重要生理过程。有学者提出采用动态变化电阻模拟呼吸过程中胸阻抗的周期变化,利用这一原理可制作呼吸模拟模块,用于输出呼吸仿真信号。为了检测呼吸模拟模块输出信号的频率,确保模拟模块的可靠性,本文提出了一种检测基于电阻抗法呼吸模拟模块仿真信号周期的方法。通过对两种常见呼吸模拟模块的实验表明,该方法可以有效测量其输出呼吸模拟信号的频率,简单有效、易于推广,有助于实现对呼吸模拟模块输出信号的精准计量,确保其可靠性。Breathing is an important physiological process of the human body.Some researchers have proposed to use dynamic resistance to simulate the periodic change of chest impedance during breathing.Using this method,a breathing simulation module can be made for outputting breathing simulation signals.In order to detect the frequency frequency of the output signal of the breathing simulation module and ensure the reliability of the simulation module,we propose a method to detect the simulation frequency of the breathing simulation module based on the electrical impedance method.Experiments on two common breathing simulation modules showed that the method we proposed can effectively measure the frequency of its output breathing simulation signals.This method is simple,effective,and easy to popularize,which helps to accurately measure the output signal of the respiratory simulation module and ensure its reliability.
