Experimental Evaluation of a Portable Oxygen Concentrator Based on Pressure Swing Adsorption

Year: 2025

Type: conference-paper

Abstract: Portable oxygen concentrators (POCs) can help reduce the load on hospitals and offer emergency care to patients in need of oxygen therapy. In this study, a POC was developed and tested at different pressures and cycling times. The device was made using low-cost materials to reduce the manufacturing cost. It was found that high air pressures resulted in an overall increase in oxygen concentration in the product air. Oxygen concentration was also found to increase as cycling time was extended. Pressurizing the air at 0.8 MPa for 15 s per cycle delivered 93% pure oxygen, which fulfills the medical need of intensive care unit (ICU) oxygen therapy.
