肺静脉压

结论外周静脉压和肺静脉压在呼吸周期中的不同表现是决定优势充盈心室的主要原因；

CONCLUSION Different experiences between peripheral veins and pulmonary vein in respiratory cycles are the principle cause determining which ventricle is prior filled .

急性左心衰时，、由于心排出量的急剧下降和或心脏前后负荷明显增加，使左心室舒张末期压和肺静脉压增高，导致肺间质和肺泡水肿，常致不同程度的低氧血症。

While acute left heart failure , there is sharp decline in cardiac output and there is increased in heart load , and significantly increased the left ventricular end-diastolic pressure and pulmonary venous hypertension , resulting in pulmonary interstitial and alveolar edema with complicated of acute respiratory failure .

心肺移植术后15分钟，持续低流量灌注组，肺静脉血氧分压明显高于间断灌注组，差异有统计学意义（P<0.05）。

15 minutes after the heart-lung transplanted , PaO2 in the lung vein at continuous low flow perfusion ( LFP ) is obvious high ( P < 0.05 ) .

且尾吊7d组变化大于尾吊14d组。3.模拟失重对大鼠肺血流动力学有影响，表现为模拟失重大鼠肺动脉压、肺静脉压、肺血管阻力增高，肺血流量降低。

The pulmonary arterial pressure , pulmonary venous pressure and pulmonary vascular resistance were increased in tail-suspension rats , while pulmonary flow was decreased . 4 .
