title: [Ventilation measurings before, during and after treatment of tracheal stenosis due to long term intubation (author's transl)].
abstract: 17 patients with post-intubation stenosis of the trachea were studied. By the extrathoracic stenosis the relative forced expiratory volume in the first second (FEV1,0) and in and expiratory flow were decreased, total airway resistance (Rt) was increased. After implantation of an endoprothesis the obstruction was significantly lowered (p less than 0,05). After removal of the tracheal endoprothesis further improvement occurred as was demonstrated by an increase in FEV1,0 an flow and by a decrease in Rt.
