A ventilator is a device that provides cool air by moving the air in or out of the lungs, inhaling a patient who is not fit to smell, or breathing properly. In this paper, a resistive chest belt sensor-based mechanical ventilator is designed to provide the COVID-19 patient with the volume of air you need to deliver with the expansion of the patient's chest in need of more air. The resistive band sensor senses the expansion of the patient's chest and controls the solenoid valve attached to the oxygen compressor. The function of the respirator is tested with the MATLAB/Simulink tool with the help of a Proportional Integral Derivative (PID) Controller and a promising result obtained.

Frequently Asked Questions
How does the resistive chest belt sensor work in this ventilator design?
The sensor detects the physical expansion of the patient's chest and uses this feedback to control the solenoid valve, delivering the required air volume.
Why is this ventilator specifically designed for COVID-19 patients?
It aims to assist patients who cannot breathe properly on their own by providing automated air delivery based on their immediate physiological needs (chest expansion).
What is the role of the PID Controller in the system?
The Proportional Integral Derivative (PID) Controller regulates the air volume delivery by processing feedback from the chest belt to ensure precision and safety.
Which software tool was used to test the ventilator's function?
The system was tested and simulated using MATLAB/Simulink to analyze the interaction between belt resistance and air volume delivery.
What is "Tidal Volume" in the context of this paper?
Tidal volume refers to the specific volume of air delivered to the lungs during a normal breath, which the ventilator must accurately manage.
How does the solenoid valve contribute to the ventilator's operation?
The solenoid valve acts as a control switch attached to the oxygen compressor, opening and closing to regulate the flow of air to the patient.
