Dimensionless study on dynamics of pressure controlled mechanical ventilation system
Yan Shi,Jinglong Niu,Maolin Cai,Weiqing Xu 대한기계학회 2015 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.29 No.2
Dynamics of mechanical ventilation system can be referred in pulmonary diagnostics and treatments. In this paper, to convenientlygrasp the essential characteristics of mechanical ventilation system, a dimensionless model of mechanical ventilation system is presented. For the validation of the mathematical model, a prototype mechanical ventilation system of a lung simulator is proposed. Through thesimulation and experimental studies on the dimensionless dynamics of the mechanical ventilation system, firstly, the mathematical modelis proved to be authentic and reliable. Secondly, the dimensionless dynamics of the mechanical ventilation system are obtained. Last, theinfluences of key parameters on the dimensionless dynamics of the mechanical ventilation system are illustrated. The study provides anovel method to study the dynamic of mechanical ventilation system, which can be referred in the respiratory diagnostics and treatment.
