Abstract

A pressure controlled mechanical ventilator with an automatic secretion clearance function can improve secretion clearance safely and efficiently. Studies on secretion clearance by pressure controlled systems show that these are suited for clinical applications. However, these studies are based on a single lung electric model and neglect the coupling between the two lungs. The research methods applied are too complex for the analysis of a multi-parameter system. In order to understand the functioning of the human respiratory system, this paper develops a dimensionless mathematical model of double-lung mechanical ventilation system with a secretion clearance function. An experiment is designed to verify the mathematical model through comparison of dimensionless experimental data and dimensionless simulation data. Finally, the coupling between the two lungs is studied, and an orthogonal experiment designed to identify the impact of each parameter on the system.
