[The x-ray functional characteristics of chronic bronchitis].

A significant correlation has been established at comparison of fluorographic findings with respiratory mechanics in bronchitis chronic between the diaphragm height, its curvature in the lateral view and FEV for the 1st second. Less apparent correlation exists between residual lung capacity and the diaphragm height, forced expiration volume and the width of the pulmonary artery right branch. Tracheobronchial dyskinesia was diagnosed in 62.2% of bronchitis patients. Chronic nonobstructive bronchitis is characterized by a short-term (> 1 s) prolapse of the tracheal posterior wall and primary bronchi which lasts longer (1-3 s) in chronic obstructive bronchitis.
