Abstract
Air spirometry and helium and oxygen (He-O2) spirometry techniques were compared. He-O2 spirometry was used to detect early occupational lung disease by studying functional impairments in the small airways in flax workers and coal miners. In flax workers, air and He-O2 flow volume curves showed decreased flow rates in a high dust exposure group after a work shift. No change was noted in controls. In a low dust exposure group, only He-O2 spirometry detected decreased post shift flow rates. The author noted that the results obtained from HeO2 spirometry were equivalent to those obtained by air spirometry and concludes that random screening using He-O2 spirometry currently is not recommended.
