Prediction of Pneumonic Oxygenation in a PID-embedded Electro-pneumatic Pressure-Controlled Ventilator Device

Abstract

Respiratory-type infections of pandemic scale have shown the critical need for suitable ventilator-type for hospitalized patients. While volume and pressure control ventilators are commercial abundance in a clinical setting, the choice of which type is considered a determinant factor in recovery during a large-scale medical emergency. A novel design of the PID architecture with the capacity to mimic the native human lung under the pathological condition of covid-19 type infection is presented. Traction of oxygenation circuit is achieved via electro-pneumatic protocol based on coupled solenoid-energized valve over a computer-controlled electro-pneumatic workstation. Our observations showed the performance of the Pressure-controlled ventilator (PCV) system in terms of peak time, settling time and maximum overshoot yield improved oxygenation throughput. The performance of the lungmimicking PID-based control mechanism is attributed to smoothing the control of inspiratory pressure and consequently impacting the compliance in the modeled pulmonic vessel.
