Small airway lesions in chronic obstructive pulmonary disease are insidious and complex, and traditional indicators lack sensitivity. Early diagnosis and precise management still pose challenges. The study focuses on the clinical value and detection techniques of small airway lesions, emphasizing the importance of early identification, functional assessment, and personalized intervention. Strategies are proposed to optimize functional indicators, expand respiratory impedance measurement, flexibly monitor expiratory flow fluctuations, and integrate multimodal functional testing, aiming to promote the refinement of the pulmonary function testing system, improve early detection rates, and enhance disease management effectiveness.
