Identification of Phenotypes of COPD Using Respiratory Impedance (original) (raw)

The study investigates the use of forced oscillation technique (FOT) in identifying phenotypes of chronic obstructive pulmonary disease (COPD), specifically distinguishing between emphysema predominant, chronic bronchitis predominant, and mixed phenotypes. Through a retrospective analysis of nine COPD patients, varying parameters in lung function tests and FOT results revealed significant differences based on phenotype, despite similar degrees of airflow limitation. The findings suggest potential implications for tailored therapeutic approaches based on the underlying phenotypic contributions to COPD.
