Diy Ventilator: Using Arduino and Blood Oxygen Monitoring to Assist Pandemic Patients

During the COVID-19 pandemic, the shortage of hospital-grade ventilators led to a surge in the development of open-source hardware mechanical ventilators (OSH-MVs). This resulted in a fragmented design space with varying degrees of innovation and functionality. To help researchers without a background in biomedical engineering, we created a taxonomy system that analyzes ten design properties through three criteria: buildability, adaptability, and scalability. We applied this system to seventeen OSH-MV projects, highlighting the strengths and weaknesses of each and suggesting possible directions for the field's development.
