[Impaired bronchial patency in patients with idiopathic interstitial pneumonias].

Idiopathic interstitial pneumonias are well-known to be mainly characterized by restrictive ventilation dysfunctions and a diminished lung diffuse capacity. No separate significance is generally attached to bronchial obstructive disorders that may be detected along with restrictive ones in some patients. The made analysis of the ventilation capacity of the lung in 53 patients with idiopathic interstitial pneumonias has revealed impaired bronchial patency in 47.2% of the cases, which gives grounds to study this problem in future.
