静脉压(venous pressure)是指在右心房水平上测得的静脉血压，正常值因测量部位而异。肘静脉压正常值为0．30—1．42kPa(30—145mmH20)，平均0．97kPa(99mmH20)，男性较女性略高，儿童与成人相同。测定静脉压用以判断有心功能、回心血容量及静脉血回心受阻情况。右心衰竭、缩窄性或渗出性心包炎、阻塞性肺气肿、上腔静脉受压或血栓形成时，均可使静脉压升高；休克、昏厥时则降低。
中心静脉压测定在鉴别诊断上有重要意义。

肝静脉压力梯度(HVPG)测定是评估门脉压力的标准方法，且HVPG也与其并发症的发生有关。
Measurement of hepatic venous pressure gradient (HVPG) is a standard method for the assessment of portal pressure and correlates with the occurrence of its complications.
