Background: Pulmonary function test, particularly in patients with COVID-19, is problematic because it involves forced expiration.Impulse oscillometry (IOS) reduces the potential exposure of health-care staff to infectious droplets.In this study, we investigated the correlation between IOS and spirometry and whether IOS can precisely predict spirometry-based diagnoses of chronic obstructive pulmonary disease (COPD).

Methods: We retrospectively analyzed the data (January 1 to December Prostate 31, 2021) of patients who underwent both spirometry and IOS on the same date.One-way analysis of variance was performed to evaluate Stockings the IOS results of patients stratified into two (COPD and non-COPD) groups by spirometry results.IOS results were also analyzed using receiver operator characteristics curves to diagnose advanced COPD, which was indicated by a postbronchodilator (BD) forced expiratory volume in 1 s (FEV1)/forced vital capacity (FVC) ratio of 160 moderately predicted spirometry-based COPD diagnosis.

Conclusions: BMI-adjusted airway resistance is a potential predictor of spirometry-based COPD diagnosis; the cutoff values of this parameter differ between individuals with and without obesity.
