Pakistan lacks domestic manufacturing of medical devices, and recent inflation alongside rupee devaluation has driven up the prices of imported medical devices. The supply and demand crisis for supplemental oxygen during the COVID-19 pandemic underscored the importance of portable oxygen concentrators, as oxygen is essential for all physiological functions. This initiative applied reverse-engineering to design and develop a prototype portable oxygen concentrator using pressure swing adsorption technology, with integrated sensors and enhanced filters for improved efficiency and effectiveness. The prototype underwent various tests to verify that it met the intended objectives. This effort aimed to initiate local, cost-effective manufacturing of oxygen concentrators in Pakistan, contributing towards the United Nations Sustainable Development Goal 9, Industry, Innovation, and Infrastructure.
