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.
在对猫进行的急性闭胸实验中,作者通过超声方法研究了低位叶肺动脉和静脉中的血流、肺动脉血压、在人工通气频率或潮气量增加时静脉输注混合脂肪酸所致实验性肺水肿中的肺血管阻力。结果表明,肺水肿时增加频率的人工通气可降低肺动脉压力升高、肺血管阻力,并增加肺动脉和静脉中的血流。增加潮气量的人工通气比初始通气时肺动脉压力升高和肺血管阻力增加更强烈,但血流略有变化。作者认为,肺水肿时增加频率或潮气量的人工通气,由于肺循环改变,在开始时可降低肺水肿的强度。
