Pseudophysiologic emphysema resulting from severe small-airways disease.

abstract：:The severity of breathlessness at given degrees of airway obstruction varies between patients with asthma. It has been postulated that the symptoms during bronchoconstriction are determined in part by involvement of airway inflammation. We compared the severity of breathlessness at various degrees of acute airway obst...
