[Methodological and experimental studies of jet ventilation--indications and limits of the procedure].

Results of experimental and methodical investigations of so-called "Injector-Ventilation" or jet ventilation verify procedures' safety regarding ventilation and anaesthesia management. Classification of jet ventilation permits delimitation to IPPV and different methods of HFV. Resulting from considerations, especially based on reported insignificancy of "Venturi-Effect" under clinical conditions, authors suggest use of unitary term "Normo-Frequent Jet Ventilation" (NFJV).
