Continuous central pressure monitoring and simultaneous continuous infusion via the same central venous catheter are sometimes necessary. Based on theoretical calculations and experimental measurements, we have determined that pressure monitoring is essentially unaffected if the continuous infusion rate is 50 ml.h(-1) or less for an adult and a paediatric central catheter. At rates > 200 ml.h(-1), the central venous pressure is exaggerated by up to 4 mmHg and 8 mmHg for the adult and paediatric catheters, respectively.
有时需要通过同一中心静脉导管进行连续中心压力监测并同时进行连续输注。基于理论计算和实验测量,我们已确定,如果成人和儿童中心导管的连续输注速率为50 ml·h⁻¹或更低,则压力监测基本不受影响。当速率>200 ml·h⁻¹时,成人和儿童导管的中心静脉压分别会被高估高达4 mmHg和8 mmHg。
