Interpretation | restriction
(1) Spirometry | qualitative assessment
Overall diminished flow-volume curve: egg-shaped
(2) Spirometry | quantitative assessment
Vital capacity reduced to 50% of the predicted value with normal tiffeneau index.
(3) Bodyplethysmography residual volume
Residual volume at normal values with total lung capacity decreased to 70%. The severity classification takes place with respect to vital capacity, so that the restriction present is still only moderately severe.
(4) Bodyplethysmography flow-pressure-curve
Unremarkable, with a cutting angle of the loops < < 90°.
(5) Functional tests
(6) transfer factor
Formally severely reduced transfer factor in association with considerable distribution disturbance.
Moderately severe restriction with considerable distribution disturbance.
