Sensitively assessing bronchial reversibility by spirometry is difficult in patients with serious airflow limitation and the elderly. Some patients cannot exhale for ≥6 s to achieve FVC testing criteria. The aim of this study was to assess if FEV 3 could be a more sensitive and an acceptable surrogate for evaluating bronchial reversibility in such patients.
