PURPOSE: Increasing evidence indicates that inflammation of peripheral airways plays an important role in the pathophysiology of obstructive lung disease and may correlate more closely with severity of dyspnea than spirometric parameters. Impulse Oscillometry (IOS) is a well validated and effort-independent tool which allows for distinguishing proximal airway resistance (R20) from total airway resistance (R5). Limited data are available regarding the relative contribution of the small airways to overall resistance in patients with different pathophysiology and severity of disease. We hypothesized that sites of resistance as demonstrated with IOS would vary with different patterns of impairment and severity of disease.
