title: [Comparative methodologic studies of closing volume and increase in airway resistance volumes].
abstract: The early recognition of obstructive lung diseases plays an important role in the subsequent therapy; the closing volume, determined by means of single-breath oxygen test has been established as a suitable parameter. This technique, however, has not succeeded as a routine method due to prohibitive costs. In a clinical study the closing volume and the easier estimatable so-called flow-resistance elevation volume (Ros-volume-curve parameter obtained from oscilloresistometry/volumetry) were compared and a correlation sought. It could be concluded, that for characterization of small airways diseases the closing volume is a more suitable parameter than the flow-resistance elevation volume.
