Abstract Background Cough in the patients with cough variant asthma is triggered by bronchoconstriction which responds to bronchodilator therapy. Following airway narrowing induced by inhaled methacholine deep inspiration DI causes dilation of the airways in both asthmatic and non-asthmatic subjects. The aim of the present study was to investigate the relationship between bronchodilator effect of DI and bronchoconstriction-triggered cough. Methods We measured airway responsiveness to methacholine using partial and full flow-volume curves in 28 healthy adults. The expiratory flow at 40 above residual volume from the full forced vital capacity MEF40 was .
