ABSTRACT
Objective To study the clinical effect of continuous central venous pressure monitoring and select a better method for central venous pressure momtoring. Methods Continuous central venous pressure wag monitored by connecting pressure sensor to central venous catheter in 56 patients with open heart operation.At the same time routine monitoring method was used in the same central venous vein of the saine patient The CVP values from the two methods were compared for 100 times and analyzed the difference.Results The VCP values of the two groups had no statistical difference(P＞0.05).Conclusions Continuous monitoring by pressure sensor had advantages such as continuous data,dynamic,direct-viewing,Veracious and decreased chance of infection.It could reduce the workload of nurses and possessed more clinical value compared with routine monitoring method.
