Abstract

|
Chronic obstructive pulmonary disease (COPD) may be irreversible disease, when a patient becomes symptomatic and/or shows abnormal results in pulmonary function test. Recently better tests have been developed in order to detect early phase of airway obstruction, when disease process is still reversible. Among them, three newer tests are believed to be more senstive to abnormalities in the peripheral small airway disease. They are frequency dependent dynamic compliance, closing volume, and isoflow-volume(Viso). Although these tests can be used to detect abnormalities in peripheral small airways, but there is very little value in pathologic confirmation of these physiologic changes. So we must try to confirm the relation between physiologic and pathologic small airway disease.
