AbstractThe effects of high frequency jet ventilation (HFJV) were investigated in 12 mongrel dogs with normal lungs. A newly developed HFJV device with purely pneumatic regulation was used. In order to evaluate several ventilatory parameters, respiratory rate, breathing time quotient and jet emission pressure were varied. Thus, important ventilatory, hemodynamic and calculated values were recorded. Accordingly, HFJV is possible with the tested device under clinical conditions in the frequency range between 80 and 300/min, with a breathing time ratio of 1:21 to 1:1 and a driving pressure up to 0.4 MPa with an oxygen concentration of FiO2 = 0.21 to 1.0. Before clinical use, however, investigations on the damaged lung of the dog are necessary.
