METHOD OF COMPATIBLE JET-STREAM ARTIFICIAL LUNG VENTILATION DURING ENDOTRACHEOBRONCHEAL OPERATIONS IN CONNECTION WITH TUMOR AND SCAR STENOSES OF CENTRAL BRONCHI AND/OR TRACHEA AND DEVICE FOR ITS REALISATION
METHOD OF COMPATIBLE JET-STREAM ARTIFICIAL LUNG VENTILATION DURING ENDOTRACHEOBRONCHEAL OPERATIONS IN CONNECTION WITH TUMOR AND SCAR STENOSES OF CENTRAL BRONCHI AND/OR TRACHEA AND DEVICE FOR ITS REALISATION
FIELD: medicine.;SUBSTANCE: inventions relate to medicine, namely, to anesthesiology, and can be used in case of operative interventions in patients with tumor and/or scar stenoses of central bronchi and/or trachea. Artificial lung ventilation is realised by means of special device including compressor of compressed medicinal air, pressure regulator, lever jet interrupter, apparatus for high-frequency artificial lung ventilation and double nozzle with diametre of both nozzles 3 mm, installed in proximal part of tracheobronchoscope tube. One nozzle is connected with said compressor, pressure regulator and lever jet interrupter, and said apparatus for high-frequency jet-stream lung ventilation is connected with other nozzle of double nozzle for realisation of high-frequency jet-stream lung ventilation with pure oxygen. After intubation of trachea with tube of rigid tracheobronchoscope with installed in its proximal part double nozzle, high-frequency apparatus jet-stream ventilation with pure oxygen is performed through first nozzle with frequency 100-180 cycles per minute, with working pressure 100-200 kPa. Additionally, through second nozzle simultaneously parallel standard-frequency manual jet-stream lung ventilation with compressed medical air is performed with frequency 20-40 cycles per minute with working pressure 100-150 kPa until patient's state is compensated. At the stage of mechanical manipulations simultaneously or successively parallel or alternately combined or only high-frequency apparatus jet-stream lung ventilation with pure oxygen is performed. At the stage of argonoplasma coagulation with high activity of argon arc successively alternately standard-frequency manual jet-stream lung ventilation with compressed medical air is performed.;EFFECT: inventions allow to reduce considerably risk of respiratory mixture inflammation and occurrence of respiratory way burn when performing argonoplasma manipulations due to controlled change of oxygen concentration in respiratory mixture in process of operation, ensuring at the same time optimal blood oxygenation and adequate removal of carbon dioxide when carrying out artificial lung ventilation.;2 cl, 3 dwg, 4 ex
