Design and Implementation of a Portable Ventilator with Variable Breath per Minute (BPM)

The Covid-19 pandemic underscored the critical role of ventilators in society, prompting attention to the shortage and cost of medical ventilators. This study focuses on the development of a portable ventilator designed for use in resource-limited settings, addressing the need for a small, lightweight mechanical ventilator. The device, controlled by an Arduino microcontroller, features adjustable ventilation modes and monitoring capabilities for vital signs. Utilizing a cam arm mechanism and a touch screen LED display, the ventilator aims to provide reliable and cost-effective ventilation. Evaluation includes performance, usability, and safety assessments. The device, weighing 11 lbs. and measuring 6.6 x 11.4 x 9.4 inches, contributes to accessible and portable ventilators for emergency situations, benefiting rural communities with vulnerable populations and limited hospital ventilators. The ventilator system, powered by an internal battery lasting up to three hours, offers hot-swappable detachable and external batteries for extended ventilation.
