Pulmonary Function Testing.

NIOSH 1986 Sep:155-170
The use of pulmonary function studies in the evaluation of pneumoconiosis was discussed. Pulmonary function tests provided a quantitative index of lung function impairment and were capable of detecting abnormalities not evident on chest x-rays or by clinical symptoms. There were a large number of lung function tests available, some of which were specific for particular types of lung alterations and useful in determining the mechanism of a noxious agent's action. Considerations for the selection of lung function tests in a given situation were summarized and their usefulness in epidemiological studies were discussed. The expertise of staff who administer pulmonary function tests was considered critical in determining the accuracy of test results. Methods for reducing the wide intersubject variability in the interpretation of pulmonary function tests were discussed. Prediction equations based on findings in asymptomatic nonsmokers in general population samples were presented. The patterns of pulmonary function abnormalities characteristic of specific lung disorders were described. The difference between the clinical and statistical significance of lung function test abnormality was discussed. The use of provocative tests to evaluate the general state of bronchial reactivity or to identify factors leading to acute bronchospasm were considered unsuitable for large scale studies due to the necessity of physician attendance and the risks of the tests. The research needs in the application of pulmonary tests to occupational disease studies were identified.
