[Model and experimental animal studies of the use of hand-controlled catheter-jet-ventilation (CJV) by plastic replacement of the tracheobronchial tree].

Pressure and volume flow measurements were performed on a simple model of the tracheobronchial tree using a catheter-jet-ventilation apparatus. This type of respiration is particularly favourable in tracheo-bronchial surgery, i.e. resections and anastomosing, due to the experience of model as well as animal experiments. Under consideration of the particularities of catheter-jet-ventilation, this type of respiration provides excellent conditions for the surgeon. This is valid for the overview of the site of operation and possible manipulation within this region. This method of respiration is suggested as a reliable tool in the hands of less skilled anaesthetists, too, for its easy handling.
