THE PECULIARITIES OF VENTILATION-SUPPORT IN ENDOSCOPIC SURGERY OF STENOSIS OF TRACHEA AND LARGE BRONCHES

S.M. Chorny, A.B. Sanginov, I.V. Mosin

At the investigation the value of influence of high frequency flow ventilation of lungs (HFFV) on lung gas-metabolism under endoscopic operations on trachea and large bronches is made. It is established that HFFV secures more oxiganation of arterial blood under lower transpulmonal pressure that decreases potential risk of barotraumas of lungs. Under imposition of largesize-manipulaters into tubus of bronchoscope positive pressure at the end of expiration is developed. Therefore because of the contrainlications to high end-expiration pressure the breathing-frequency is needed to decreasing.

Keywords: trachea stenosis, bronchoscopic operation, ventilation-support.
