  • Description: Availability of a reliable oxygen (O2) supply is critical for hospitals in developing countries. The AIDS pandemic that is associated with severe pulmonary infections has further enhanced this problem. Today in 2006, even though a number of financially viable solutions adapted to conditions in developing countries are available, lack of oxygen is still a cause of death in Africa including in some capital cities. Hospitals in industrial countries have wall outlets supplied from liquid O2 storage tanks (-183 degrees C). However this solution requires advanced cryogenic technology with storage as well as transportation of liquid O2. In developing countries, O2 is supplied from pressurized O2 cylinders (200 bars) sometimes stored in racks to supply wall outlets but more often moved from bed to bed as needed. This solution is expensive because of the cost of transportation on poor roads in all areas outside capital cities. Frequent supply shortages lead to major disruptions in care quality. Properly maintained O2 concentrators can provide a highly effective low-cost easy-to-use solution for health facilities in developing countries. The pressure swing adsorption (PSA) process based on reversible nitrogen adsorption is a reliable economical autonomous oxygen production process ideally suited to hospitals in developing countries. It can be used to supply wall outlets or fill cylinders. Return on investment is achieved within one to two years.
