Abstract
In these unprecedented times of COVID-19 pandemic, globally there has been a shortage of medical supplies, hospital beds, health care workers, etc. This was accentuated in India with a shortage of oxygen in the second wave of pandemic. The reasons for shortage were mainly imbalance between demand-supply and these also led to implementation of ingenious solutions in the form of oxygen generators based on PSA technology. The technology was an off shot from OBOGS developed by DRDO and DEBEL for light combat military air crafts. This review discusses the scientific technology behind medical oxygen plants based on PSA, its applications and its advantages to combat the dearth of oxygen.
