ABSTRACT
In anesthetized rabbits, the occurrence of histopathological changes was studied above below and the level of the endotracheal tube opening after one-hour high-frequency jet ventilation (f = 150.min-1,Pin = 70-90 kPa, Ti = 0.5) with nonhumidified air and oxygen mixture (FiO2 = 0.6). The findings were compared with those obtained in intact rabbits and in rabbits which were inhaling nonhumidified air from the environment spontaneously via the endotracheal tube. Mechanical obstruction of the airways by mucus or necrosis of the mucous membrane was not observed. The major histopathological changes characteristic of inflammation and mechanical damage of the mucosa were recorded above the opening of the endotracheal tube. Towards the main bronchi the degree of the injury was decreasing. (Tab. 2, Fig. 2, Ref. 11.)
