Design and Implementation of Mechanical Ventilator for Respiratory

Patients with respiratory diseases experience shortness of breath and a severe drop in blood oxygen levels. Unfortunately, improper handling can lead to death. Hence, there is a growing demand for medical respirators across the globe. In order to represent the lung states of normal breathing and mechanical ventilation, the mechanical ventilation model favors a stronger positive evolution. In the intensive care unit, patients who cannot breathe are usually spontaneously ventilated using a pressure - and volume - controlled mechanical ventilation system. The purpose of this article is to generate and reproduce a PCV signal. First, let's take a closer look at these two ventilation methods. The second step is to analyze the proposed Simulink model. This model uses existing procedures from the Simscape Fluids (gas) library to reproduce all the pneumatic components used in some commercial intensive care ventilators. To validate the Simulink model, the simulated results of two forms of pressure, tidal volume, and inspiratory/expiratory flow were compared with actual quantitative trends obtained from previously recorded real-world tests. In addition, doctors and students will be able to use it to evaluate how the ventilator responds to different patients.
