PURPOSE: Documentation of significant FEV1 reversibility as defined by ATS has been the cornerstone for diagnosing reversible airway obstruction in asthma. All drug trials for asthma mandate significant FEV1 reversibility as criteria for recruitment. However, only about 30% of patients with asthma have significant reversible airway disease. Therefore, we explored the utility of performing lung volume reversibility in addition to spirometry testing in patients with persistent asthma.
