title: [Comparison of oscillation method and body plethysmography for assessment of airway resistance (author's transl)].
abstract: Airway resistance was measured by body plethysmography and also by an oscillographic method for assessment of the impedance of the respiratory tract. The results were compared in 42 unselected patients. The correlation between the two values for airway resistance was satisfactory (r = 0,804 p less than 0,001). However, when correlation was sought between each type of resistance-value and other lung function data (FEV1, IGV), the resistance measured by plethymography correlated better than the one measured by the oscillation method. This difference was even more pronounced when 21 patients with manifest bronchospasm were reevaluated after bronchodilatation. Nevertheless, the oscillation method for assessment of the resistance of the respiratory tract serves as a new and practicable tool for bed-side lung function testing, as well as for testing of patients who are unable to cooperate for routine spirography.
