Method of separate bronchospirography with the use of bronchofibroscope and its clinical value in lung cancer patients.

: In this paper the authors describe: a method of bronchospirography with the use of bronchofibroscope; a method of simultaneous performance of bronchospirography and bronchofibroscopy; criteria of indices and staging of each lung ventilation capacity; patterns of interrelation of the "healthy" and disabled lung according to the degrees of lung ventilation disturbance; indications and contraindications to operative treatment based on bronchospirographic data. For evaluation of the operability bronchospirographic investigations of the lung ventilation capacity were carried out in 225 lung cancer patients.
