Relationship between concavity of the flow-volume loop and small airway measures in smokers with normal spirometry

Relationship between concavity of the flow-volume loop and small airway measures in smokers with normal spirometry

Abstract Background There is increasing evidence of small airway abnormalities in smokers despite normal spirometry. The concavity in the descending limb of the maximum expiratory flow curve (MEFV) is a recognised feature of obstruction and can provide information beyond FEV1, and potentially early...
