The effects of salbutamol aerosol on lung function in patients with pulmonary emphysema

摘要: Abstract The effects of inhaling 400 μg salbutamol were compared with identical placebo inhaler in a double blind cross-over study 20 patients radiological evidence pulmonary emphysema. There was small but significant rise the forced expiratory volume one second (FEV 1 ), there much greater increase vital capacity (VC), which accompanied by reduction residual volume. Symptomatic improvement after reported 14 and VC increased significantly this group; no who did not prefer active inhaler. consistent change FEV /VC ratio administration is misleading as an indicator bronchodilator responsiveness Salbutamol thus valuable addition to treatment emphysema response best judged measuring VC.
