ANFIS based Mathematical Model of Mechanical Ventilator

The modern industrial revolution and the spread of viruses have resulted in an increase in respiratory diseases and lung cancers. These problems arouse the interest in research on artificial respirators and their mechanism of operation and control. Obtaining a mathematical model of mechanical ventilator helps in demonstrating its behaviour during the process of artificial ventilation. To address this research problem, this study aims to validate the impact of a newly developed mechanical ventilator model on patient’s lungs. It compares the new ANFIS-based model with an existing mathematical model of mechanical ventilator. The simulation of both ventilators in Matlab includes certain parameters namely respiratory rate (RR), positive end-expiatory pressure(PEEP), tidal volume and pressure wave. The developed model demonstrates high accuracy in comparison with the existing model. Changing one of these parameters reveals its influence on the lungs’ volume, flow and PV loop. The MATLAB simulation constitutes a uncomplicated environment for testing and observation respiration parameters (flow, dynamic compliance and volume) during artificial ventilation. The simulation results are promising as this facilitates studying any type of ventilation modes virtually without jeopardizing the life of mankind in clinical trials.
