[High-frequency jet ventilation and the function of the right heart--an animal experimental study].

In a controlled study, 10 dogs with normal and severely damaged lungs were subjected to nuclide angiocardiographic investigations into the function of the right ventricle. The pulmonary injury was produced by infusion of oleic acid (OA) into the right atrium during controlled ventilation (IPPV). The angiocardiographic examinations were performed using 133Xenon in the first pass technique.

[Functional scintigraphic studies of perfusion and ventilation during high frequency jet ventilation (HFJV)].

In a controlled study, functional-scintigraphic investigations into perfusion and ventilation were performed on 10 dogs with non-damaged and extremely severely damaged lungs. The pulmonary damage was produced by injecting oleic acid (OA) into the right atrium of the heart under controlled ventilation (IPPV). The scintigraphic examinations were carried out using 133Xenon.
