Employing the Forced Oscillation Technique for the Assessment of Respiratory Mechanics in Adults

[The forced oscillation techniques in the detection of bronchial obstruction in patients with pulmonary tuberculosis]
Abstract:
Clinical trials of the forced oscillation (FO) technique could identify criteria for bronchial obstruction: viscosity airway resistance (VAR) (R(fo), R(in), R(ex)), and its frequency dependence. VAR studies promoted detection of bronchial patency in further 21.9% of the patients who had no bronchial obstruction, as evidenced by spirography (SG) and F-FEV curve recording. To improve the diagnosis of impaired bronchial patency, it is expedient to explore VAR by the FO technique along with the routine methods (SG and F-FEV curve recording).
