Smart simulated lung is a monitoring of gas flow (tidal volume), gas pressure and concentration of gaseous oxygen and other parameters which can display apparatus of these parameters and waveforms. This paper discussed the content of the simulated lung device embedded control systems, flow sensor and pressure sensor circuit detection of respiratory parameters and the flow rate of acquisition principles.%智能模拟肺是一种具有监测气体流量(潮气量)、气体压力和气体氧浓度等参数,并且能够显示这些参数及其波形的装置.主要讨论该模拟肺装置中嵌入式控制系统的内容,介绍了采用流量传感器和压力传感器实现检测呼吸参数的电路以及流速采集原理和程序流程.
