PURPOSE: In patients with COPD, the severity of airflow limitation has previously been demonstrated to weakly correlate with impedance as assessed by forced oscillation technique (FOT). Since physiologic phenotypes of COPD encompass a mixture of airway disease (chronic bronchitis) and parenchymal disease (emphysema), we hypothesize that the variable contributions of these disease processes will determine the pattern of abnormality on FOT. The present study evaluates the role of FOT in distinguishing COPD phenotypes in patients characterized by standard pulmonary function tests, esophageal manometry, and imaging.
