Trends in the supply of oxygen in hospital--oxygen concentrators--Korle Bu experience.

The supply of Oxygen to hospitals in the West African subregion has been irregular for decades. This has added to the frustrations of Anaesthetists in the subregion. The availability of devices that absorb Nitrogen from the atmosphere, leading to an end product of high O2 concentration, appears to be the answer to chronic oxygen shortages in the developing countries. Korle Bu Hospital, Accra, has been producing its own oxygen within the hospital since 1986. Oxygen Concentrators are recommended as a solution to a chronic problem.
