Emergency Ventilator Machine

We, Team IUT Mars Rover, strive to design a mechanical ventilator that can effectively support patients with Acute Respiratory Distress Syndrome in emergency situations and resource-constrained settings, which will be significantly easier to implement considering our country's (Bangladesh) capabilities. Our objective is to achieve this by automating the Bag Valve Mask (BVM), eliminating the need for human operators to repeatedly compress the BVM, a physically demanding task that often results in incorrect execution. By incorporating precise parameters and an assist control mode, we aim to automate the process efficiently. The ventilator's lightweight design will ensure portability, making it easier to transport and use in various settings. In our design, most of the components can be 3D printed, enabling mass production in a shorter timeframe. Our system allows users to input breath rate, tidal volume, and Inspiratory-to-Expiratory (I/E) ratio parameters. We will employ pressure sensors and flow rate sensors to accurately measure pressure and airflow rates. By utilizing these variables, we can determine the optimal pressure settings for each patient. The entire system will be powered by a rechargeable battery, while an Arduino Mega microcontroller will serve as its intelligent core, processing data and executing commands seamlessly.
