Forced oscillation technique in progressive pulmonary fibrosis in a single-center retrospective study.

ABSTRACT: The contribution of forced oscillation technique (FOT), also called oscillometry, in diagnosis and follow-up of progressive pulmonary fibrosis (PPF) is not yet established. The aims of this monocentric retrospective study were to compare the FOT profile between patients suffering from PPF and stable non-idiopathic pulmonary fibrosis (IPF) interstitial lung diseases (ILDs), to look for a correlation between oscillometry and conventional function tests currently used for PPF follow-up and functional definition (forced vital capacity (FVC) and diffusing lung capacity (DLCO)) and correlation with ILD severity according to FVC. Compared to non-IPF stable ILDs (n = 96), PPF patients (n = 45) showed lower median resistance at 5Hz (X_rs5) values (during inspiratory phase: 0.31 versus -0.
