Portable Ventilator Using Ambu Bag for Patient Care and Mobility

Abstract

The global demand for accessible, affordable, and portable respiratory support systems has intensified, especially in emergency and low-resource settings. This project presents the design and development of a compact, portable ventilator that automates a manual resuscitator Ambu bag (Artificial Manual Breathing Unit) to provide life-saving ventilation support for patients in need of respiratory assistance. The system integrates a microcontroller-controlled mechanism to compress the Ambu bag at adjustable rates and volumes, ensuring customizable ventilation according to patient needs. Emphasis is placed on affordability, ease of use, and mobility, making it suitable for use in ambulances, rural clinics, and disaster zones. Key features include battery operation, simple user interface, pressure monitoring, and fail-safe mechanisms to ensure patient safety. The proposed solution bridges the gap between manual ventilation and expensive hospital ventilators, offering a practical alternative for both emergency response and continuous patient care during transport or in remote areas.
