title: [Functional diagnosis of CNSLD in epidemiological surveys-results of the population study in Halle 1974 (author's transl)].
abstract: The problems of lung function testing methods in epidemiological studies were assessed in a study population of 853 men aged 40-70. The Helium-rebreathing-method, the X-ray densitometry, the oxygen-method were evaluated for the estimation of the residual volume in epidemiological conditions. The Pneumotest was proved for measurement of unequal ventilation. The necessity of reference values for these methods is discussed.
