基于LabVIEW呼吸机时间切换通气模式的建模仿真

Computer Simulation of Mathematical Model of Time-Cycle Mechanical Ventilation Based on LabVIEW

呼吸机是医用必备工具,在临床应用中越来越普遍。虚拟技术能够为医生制定医疗方案提供一定的帮助。采用LabVIEW软件虚拟呼吸机前面板,并对呼吸机气流源、气管、肺等部分进行,建模。采用计算机动态模拟时间切换机械通气中物理过程,建立理论曲线快速演示和快速分析平台,探讨其它原理机械通气计算机仿真的可行性。

With sofeware of Laboratory virtual In-strument Engineering Workbench,to build a series of simulation system separtely for flow soure of ventilator,torachea,bronchiaand lung by building modie.To simulate the mathematic expressions of the five subfunctions of one total time-cycle ventilatory period dynamically by computer programming and build a platform for demonstration and analysis of the theoretical curves,and to discuss the feasibility of the simulation of ventilation based on other cycling principles.
