[Changes in bronchial resistance after surgical treatment of obstruction of the upper airways].
Parameters of total, nasal, and tracheobronchial airways resistance and other parameters of lung ventilation were measured in 55 patients with clinical signs of nasal obstruction. After successful surgical operation Rtot, Rn, Raw, functional residual capacity, minute volume of ventilation and breathing frequency decreased whereas maximal expiratory flow rate, one-second forced expiratory volume, vital capacity and tidal volume increased. These changes give evidence that the tracheal and bronchial tone improved and the efficacy of lung ventilation increased.
