Still controversial: Small airway is considered the primary defect in asthma but one cannot diagnose the presence of asthma by small airway obstruction alone. In fact it is often present in seemingly well controlled asthma. I presume that your fvc and fev-1 were normal and thus would not lose sleep over it. COPD is also not diagnosed by this measure.
