A simple Design of Automatic Bag Valve Mask Ventilator using arduino

This paper presents a ventilator that is characterized by simple construction and operation, as well as accurate execution of tasks due to the control system based on the Arduino board and servo motor. The device presented in this research is composed of two main parts: the mechanical part, represented by pliers, which are two opposite plates that can be moved at a specific angle and speed with the assistance of a servo motor connected to these two pliers by two iron rods, and the electronic part, which serves as the base for the ventilator described in this paper. The electronic component consists of a keypad, an Arduino board, and a servo motor. a display screen that shows the user-entered settings is also included. The main goal of this paper is to accurately adjust the amount of oxygen flowing to the patient through the ability of this device to determine the angle of the motor, and the number of breathing times that can be adjusted by adjusting the speed of the engine. A model of the proposed ventilator has been implemented and successfully tested in terms of modifying the motor angle and how rapidly the bag is pressed (motor speed). wherever the control system’s settings have all been accurately and completely applied. In comparison to other devices proposed in numerous studies, this device is characterized by the simplicity of its design, the affordability of its parts, as well as its light weight, which makes it easier to carry and move from one place to another. It is also distinguished by its accuracy in controlling the amount of oxygen required as well as the number of breathing cycles per minute.
