Smart Portable Ventilator with Real-Time Blood Oxygen Monitoring for Affordable Respiratory Support

Abstract

The global surge in respiratory illnesses, particularly due to the COVID-19 pandemic, has intensified the demand for ventilatory support. However, conventional ventilators are often costly, bulky, and challenging to access in low-resource settings. This paper introduces the development of a Smart, Lightweight, and Portable Ventilator with Integrated Real-Time Blood Oxygen Monitoring, designed to deliver effective and affordable respiratory assistance. The proposed system utilizes a motor-driven mechanism to automate the compression of an Ambu bag, ensuring a consistent and controlled airflow for patients in critical need. A key feature of this ventilator is its real-time blood oxygen monitoring capability, achieved through an integrated pulse oximeter sensor. This enables continuous tracking of oxygen saturation (SpO₂) levels, allowing for timely interventions and enhanced patient safety. With a compact and lightweight design, the device is highly portable, making it well-suited for emergency scenarios, remote healthcare facilities, and areas with limited access to advanced medical equipment. By combining affordability, portability, and intelligent oxygen monitoring, this innovative solution addresses the urgent need for accessible ventilatory support, particularly in underserved regions. The proposed system has the potential to improve patient care and expand the availability of respiratory support worldwide.
