肺动脉楔压

目的探讨连续波多普勒超声在评估二尖瓣返流患者的肺动脉楔压中的作用。

[ Objective ] To confirm the utility of continuous wave Doppler echocardiography in assessing pulmonary artery wedge pressure in patients with mitral regurgitation .

结论连续波多普勒超声尽管在无创性评估肺动脉楔压中有一些局限性，但仍不失为一项可靠并且准确的技术。

[ Conclusion ] Continuous wave Doppler echocardiography is a useful and accurate technique which nevertheless has some limitations in the non-invasive assessment of pulmonary artery wedge pressure .

R波振幅的改变与心输出量及心脏的泵血功能，尤其是肺动脉楔压之间无明显关系。

The variation of R wave amplitude has little relation with cardiac output , heart pumping function , especially with pulmonary wedge pressure .

hc／hz在A组明显高于B组，且与肺动脉楔压间呈显著正相关。

The hc / hz ratio in group A was extremely higher than that in group B and was positively correlated to PCWP .

中心静脉压（CVP）、肺动脉楔压（PAWP）均无显著差异（P均>0.05）。

There was no difference in central venous pressure ( CVP ) and pulmonary arterial wedge pressure ( PAWP , all P > 0.05 ) .

经食管超声与心导管同步定量冠状动脉旁路移植术前后肺动脉楔压的研究

Evaluation on changes of pulmonary capillary wedge pressure in patients undergone off-pump coronary artery bypass using transesophageal echocardiography and cardiac catheterization simultaneously

目的应用经食管超声（TEE）和心导管技术同步检测微创冠状动脉旁路移植术（OPCABG）前、后肺动脉楔嵌压（PCWP）的变化。

Objective To investigate the changes of pulmonary capillary wedge pressure ( PCWP ) before and after off-pump coronary artery bypass graft ( OPCABG ) using transesophageal echocardiography ( TEE ) .

应用多普勒超声心动图对慢性心衰患者肺动脉嵌楔压的研究

Doppler Echocardiography & To Determine Pulmonary Artery Wedge Pressure in Patients with Chronic Heart Failure

观察比较两组间心律失常、死亡率、外周动脉压、肺动脉毛细血管楔嵌压（PCWP）、左心室舒张末期压（LVEDP）、左心室内径的变化。

The changes of arrhythmia , mortality , pulmonary capillary wedge pressure ( PCWP ), left ventricular end-diastolic pressure ( LVEDP ), peripheral artery pressure and the diameter of left ventricular chamber were observed .

当ICP150mmHg时，Qs/Qt由10.0±3.1%上升到16.0±5.6%（P<0.01），同时动脉血氧分压下降，肺动脉压和肺动脉楔压升高。

However , when ICP was raised to 150 mmHg for the same time , the Qs / Qt increased from 10.0 ± 3.1 % to 16.0 ± 5.6 % ( P < 0.01 ), PaO_2 decreased , and pulmonary arterial pressure as well as pulmonary arterial wedge pressure increased .

结果B组的血液动力学参数平均肺动脉压（mPAP）、肺动脉楔压（PAWP）、肺循环阻力（PVR）和平均动脉压（mABP）与A组差异均有显著性意义（P＜0.05）。

Results There were significant differences between two groups on hemodynamic values for mean pulmonary arterial pressure ( mPAP ), pulmonary artery wedge pressure ( PAWP ), pulmonary vascular resistance ( PVR ) and mean arterial pressure ( mABP ) ( P < 0.05 ) .

PAC可以连续显示肺动脉压及其他多种变量，如心排血量，也可以间断性显示肺动脉闭塞压或楔压。

The PAC allows continuous display of pulmonary artery pressure , and variables such as cardiac output and pulmonary artery occlusion pressure , or wedge pressure , can be intermittently obtained .
