CENTRAL VENOUS PRESSURE(CVP)的测量是 CCU 室的重要监护项目之一。它要求在无菌技术操作下进行准确无误的测量,以保证数值近似精确,使临床观察更加有效,有利于心脏的监护。以往在临床上所使用的 CVP 测量尺既繁琐又有误差,同时易造成污染,在病员的位置改变时,所测数值误差增大。为此,我 The CENTRAL VENOUS PRESSURE (CVP) measurement is one of the key custody programs for the CCU room. It requires accurate aseptic measurements under aseptic technique to ensure that the values ​​are approximately accurate, making clinical observations more effective and conducive to heart monitoring. In the past in the clinical use of CVP measuring ruler is cumbersome and error, and easy to cause pollution, the patient’s position changes, the measured value error increases. For this, me
