Background And Objective: Two sets of local reference values are available for spirometry in Hong Kong, but it is uncertain how well they work in the assessment of occupational lung diseases. This study examined their relative performance in the compensational assessment of silicosis.
Methods: Local reference values published in 1982 and 2006 were compared in two different populations comprising normal construction/quarry workers and silicosis patients.
Background And Objective: An updated standardization statement on measurement of DL(CO) was issued by the American Thoracic Society (ATS)/European Respiratory Society (ERS) Task Force in 2005. The aim of this study was to evaluate the effects of new recommendations on the success rate, test efficiency, measurement variability and reported results of DL(CO) testing.
Methods: We prospectively evaluated 55 Chinese patients without previous experience of the DL(CO) test in 2006.
