Abstract

A pressure-controlled mechanical ventilator with an automatic secretion clearance function can improve secretion clearance safely and efficiently. Studies on secretion clearance of pressure-controlled systems can be undertaken via clinical treatment and application. However, these studies are based on a single-lung electric model, neglecting the coupling between two lungs. Furthermore, the research methods are too complex to analyze a multiparameter system. In this paper, to grasp the essence of the human respiratory system, a dimensionless mathematical model of a double-lung mechanical ventilation system with a secretion clearance function was built. An experiment was designed to verify the mathematical model by comparison of dimensionless experimental data and dimensionless simulation data. Finally, the coupling between the two lungs was studied, and an orthogonal experiment was designed to identify the impact of each parameter on the system. View Full-Text
