静脉腔或房穿孔是使用中心静脉导管进行监护中的一大障碍。我们设计了一种带有搏动模拟膜的试管模型。用以测定可能影响不同种类中心静脉导管相对穿孔势能的一些变量。为确定中心静脉导管的穿孔势能,我们研究了下述变量的影响:(1) Intravenous or perforation of the ventricle is a major obstacle to the use of a central venous catheter for monitoring. We designed a test tube model with pulsatile simulated membrane. Used to determine some variables that may affect the relative perforation potential of different types of central venous catheters. To determine the perforation potential of central venous catheters, we examined the effects of the following variables: (1)
