摘要

自动机械呼吸机是一种标准设备,用于为有呼吸系统问题的患者提供人工通气,在普通ICU病房中很常见。它的功能是在吸气时向肺供气,呼气时将肺排出,这一功能相当复杂,用户需要经常练习才能了解所有的通气参数设置。本文采用模型仿真的方法,提出了一种简化的通风机电路,为通风机参数研究提供了一种简便的工具。我们的模型打算在VCV模式(VT, RR, TI)下使用一个简单的橡胶测试肺袋,并添加暂停时间设置。初步地,通过修正模型得到的所有主要通气波形为我们今后进一步研究另一种基本通气模式(如PCV或IMV + PEEP/CPAP)提供了有用的信息。

A ventilation parameters waveform study by using a simple ICU ventilator circuit
Automatic mechanical ventilator is a standard equipment used to provide an artificial ventilation to a patient who has a respiratory system problem and can be commonly seen in the general ICU ward. Its function is to supply airflow into lung during inspiration and remove air out from lung during expiration phase which quite complicated and user always need a routine practice in order to understand all ventilation parameter settings. In this paper, we propose a simplified ventilator circuit by using model simulation in order to use as a simple tool in the ventilation parameter study. Our model is intending to use with a simple rubber test lung bag in VCV mode (VT, RR, TI) with a pause time setting addition. As a preliminary, all main ventilation waveforms obtain from this modified model provide us a useful information for a further study in the future which will be focused on an another basic ventilation mode such as PCV or IMV with PEEP/CPAP.
