Title Oxygen enrichment of room air to improve well-being and productivity at high altitude
Bibliographic information July-Sep. 1999, Vol.5, No.3, p.187-193. Illus. 23 ref.
Abstract Increasingly, commercial and scientific activities, such as mining and observational astronomy, are taking place at very high altitudes, up to 5,000m. Frequently, workers commute to these locations from much lower altitudes. In addition, large numbers of people permanently live and work at high altitudes. The hypoxia of high altitude impairs sleep quality, mental performance, productivity and general well-being. The proposed solution is to inject oxygen into enclosed work areas through the air-conditioning system. An increase in oxygen concentration by one percentage point (e.g. from 21% to 22%) decreases the equivalent altitude by about 300m, i.e. a room at an altitude of 4,500m containing 26% oxygen is effectively at an altitude of 3,000m. This innovative technique promises to improve productivity and well-being at high altitudes.
