Tiotropium Induced Bronchodilation in Lung CT Scored Emphysema
NCT00570544
Last updated date
ABOUT THIS STUDY
To evaluate if tiotropium (Spiriva)induced bronchodilation of inspiratory capacity in
patients with moderate to severe copd subjected to metronome paced hyperventilation induced
dynamic hyperinflation is dependent upon the extent of underlying emphysema as determined by
high resolution-thin section CT lung.

Brief Summary | To evaluate if tiotropium (Spiriva)induced bronchodilation of inspiratory capacity in patients with moderate to severe copd subjected to metronome paced hyperventilation induced dynamic hyperinflation is dependent upon the extent of underlying emphysema as determined by high resolution-thin section CT lung. | |||
Detailed Description | We will analyze post hoc, data that was previously published: Gelb AF et al.Chest 2006;131:690-695. We have shown that tiotropium increases resting inspiratory capacity thereby providing lung volume protection against metronome paced hyperventilation induced dynamic hyperinflation. End point will be to correlate increase in tiotropium induced FEV 1(L) and inspiratory capacity with extent of underlying emphysema as scored by lung CT ( Gelb AF et al:Chest 1996; 109: 353-359)in 29 patients with COPD. We will also correlate the decrease in inspiratory capacity following metronome paced hyperventilation induced dynamic hyperinflation with extent of lung CT scored emphysema. | |||
