Bronchoconstriction in response to deep inhalation during spirometry testing.

In healthy individuals, airway resistance has an inverse relationship with lung volume.1 Moreover, deep inhalation is thought to maintain airway smooth muscle homeostasis and to possess bronchodilating and bronchoprotective properties against challenge agents.2-6 The bronchodilatory effect of deep inhalation is clearly impaired in asthma patients2,7,8; however, the bronchoprotective properties ...

A Suggestion on Suggestion

Effect of prior bronchoconstriction on the airway response to histamine in normal subjects.

We have examined the effect of prior bronchoconstriction on the bronchial responsiveness to inhaled histamine in nine normal subjects. The airway response to increasing concentrations of histamine aerosol was assessed by measurement of specific airways conductance (sGaw) in a body plethysmograph. The threshold provocative dose of histamine needed to cause a 35% fall in starting sGaw (PD35) and ...

Pulmonary gas exchange response to exercise- and mannitol-induced bronchoconstriction in mild asthma.

Both exercise (EIB) and mannitol challenges were performed in asthmatic patients to assess and compare their pulmonary gas exchange responses for an equivalent degree of bronchoconstriction. In 11 subjects with EIB [27 +/- 4 (SD) yr; forced expiratory volume in 1 s (FEV(1)), 86 +/- 8% predicted], ventilation-perfusion (Va/Q) distributions (using multiple inert gas elimination technique) were me...
