问:当调节血流动力监测系统零点时,如何确定正确的参考点?静脉轴线提供了大致标明左右心房和肺动脉解剖水平的外周参考点。将位于肺动脉内的导管顶端调节为血流动力监测系统的零点保证了使用导管获得血流动力值的准确性。当血流动力监测系统与静脉轴水平接近时,气液交界面(零点
Q. How do I determine the correct reference point when adjusting the zero point of the hemodynamic monitoring system? The venous axis provides a peripheral reference point that roughly indicates the level of left and right atrium and pulmonary arteries. Adjusting the tip of the catheter located in the pulmonary artery to the zero point of the hemodynamic monitoring system ensures the accuracy of using the catheter to obtain the hemodynamic value. When the hemodynamic monitoring system is close to the venous axis, the gas-liquid interface (zero point
