The usefulness of spirometry in pulmonary function testing is reviewed. Quantification of hazardous effects of occupational pollutants is limited by several factors, such as choice of test, instrument standardization, instrument calibration, standardization of test procedure, measurement and computation methods, data interpretation, and special problems in fluid testing. The experimental approach in the study of forced spirographic parameters, forced vital capacity (FVC), forced expired volume in 1 second (FEV1), the ratio of FEV1/FVC, the average flow rate measured during the middle half of the FVC, the forced expired flow (FEF 25 to 75 percent), and FEF 75 to 85 percent is described. The standardization of instrumentation is discussed. Calibration techniques are outlined. The importance of technician testing is discussed. The problems with manufacturers' recommendations with regard to their instrumentation are described. The problems with using a mobile laboratory in obtaining field samples are examined. The authors conclude that spirometry is an important tool in the epidemiological status of occupational lung disease.
