  • Title: [Biomechanics of respiration in patients with expiratory stenosis of trachea and main bronchi (author's transl)].
    Author: Joffe LZ, Rechtmann AG.
    Journal: Z Erkr Atmungsorgane; 1981; 156(3):212-7. PubMed ID: 7293276.
    Abstract:
    The results of mechanical examinations of breathing (pneumotachogram, esophagopressure, intrabronchial pressure) in 62 patients with endoscopically and roentgenologically proved expiratory stenosis of the trachea and main bronchi by invagination of the pars membranacea are given. The localization of the obstructive syndrome was mainly central in 26 cases and mainly peripheral in another 36. The examinations of mechanics of breathing allowed a quantitative estimation of the role of the expiratory stenosis in ventilation disturbance, the differentiation of functional mechanisms and the distinction of a primary and a secondary type of invagination of the pars membranacea caused by emphysema. The results serve to give indications for conservative and operative treatment as well as to check the therapeutical results.
