Abstract : COVID-19 has caused significant health crises in 2019-2021, affecting lungs and limiting lung capacity. Ventilators play a crucial role in delivering 10-30 breaths per minute, adjusting air volume, and monitoring patient blood oxygen and exhaled lung pressure. A reliable and affordable DIY ventilator is designed using a silicon ventilator bag coupled with a stepper motor. The ventilator uses a double arm mechanism for inflation and deflation, with the rate of inflation and deflation based on the motor's RPM. To alter inhalation duration and BPM values, the device employs a toggle switch and an additional pot. Blood oxygen and pressure sensors monitor vitals, and an emergency alarm is fitted to alert patients in emergency situations.

Keywords : Ventilator bag, double arm, stepper motor, pandemic, push mechanism.
