[The change of pulmonary function and working capacity of patients with healed pulmonary tuberculosis in the course of 15 years (author's transl)].

Pulmonary function (VC, FEV1, RV) and physical ability with the same methods and even apparature were assessed in patients with pulmonary tuberculosis dismissed in 1958/59 as cured or markedly improved. The values of pulmonary function gained at dismission and 15 years later were compared with the trend of the data on physical ability and disablement in the course of the years. In patients invalidated from this disease a 3 times greater reduction of VC, a 9 times higher decrease of FEV1 and nearly a 2 times greater increase of RV was found than in patients with previous tuberculosis but still on the job.
