Patient Monitoring Low – Cost Automated Ventilator

Abstract

This paper presents the design and development of a low-cost ventilator designed to address the critical shortage of ventilators during emergencies, such as the COVID-19 pandemic. The proposed ventilator is an affordable and efficient solution that integrates the essential features to support patients with respiratory issues. An Arduino-based system automates the operation of a silicone ventilator bag through a stepper motor-driven push mechanism, ensuring controlled air delivery to the lungs. The ventilator automatically adjusts air volume and pressure based on the patient’s age group, with additional manual controls for caregivers to fine-tune the volume if necessary. The device monitors key patient vitals, including blood oxygen levels, heart rate, and temperature. A mobile app serves as the primary user interface, providing real-time feedback through an LCD and enabling caregivers to track vitals and make necessary adjustments. By incorporating a compact design and low-cost components, this project delivers a reliable and adaptable solution to assist patients in critical conditions during healthcare crises.
