Validation of a Simulink Model for Simulating the Two Typical Controlled Ventilation Modes of Intensive Care Units Mechanical Ventilators

Mechanical ventilators are vital components of critical care services for patients with severe acute respiratory failure. In particular, pressure- and volume-controlled mechanical ventilation systems the typical modes used in intensive units (ICUs) to ventilate who cannot breathe adequately on their own. this paper, a Simulink model is proposed simulate these two employed lung ventilators. Firstly, described detail present paper. Secondly, suggested analysed: it consists using well-established subroutines already through Simscape Fluids (gas) library, all pneumatic some commercial ICU ventilators, such as pressure reducing valves, relief check tanks, ON\OFF proportional directional etc. Finally, simulation results both terms pressure, tidal volume, inspired/expired flow compared real-life quantitative trends taken from previously recorded experiments order validate model. The accuracy high, numerical predictions good agreement data, percentage error being less than 10% most comparisons. way, can easily be by manufacturers start-ups produce new shortest time possible. Moreover, also doctors trainees evaluate how ventilator responds different patients.
