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

Abstract

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.
