[Pulmonary circulation in experimental pulmonary edema during diverse artificial respiration regimes].
In acute experiments on cats with closed chest by ultrasonic method the authors studied the blood flow in low-lobar pulmonary artery and the vein, the blood pressure in pulmonary artery, lung vessels resistance in experimental pulmonary edema caused by intravenous infusion of mixture fatty acids at artificial ventilation of increased frequencies or volumes, at was shown, that artificial ventilation of increased frequencies in pulmonary edema reduces the pressure increase in pulmonary artery, lung vessels resistance and increases the blood flow in pulmonary artery and vein. Artificial ventilation of increased volumes produces more intense pressure increase in pulmonary artery and lung vessels resistance than in initial ventilation but the blood flow was slightly changed. The authors assume that artificial ventilation of increased frequencies or volumes in pulmonary edema due to pulmonary circulation change reduces the pulmonary edema intensity at the beginning.
