ObjectiveTo explore the accuracy and operation convenience of the new central venous pressure measuring device in clinical application. MethodsFifty patients in the intensive care unit who needed to monitor central venous pressure (CVP) were selected as the research objects. The CVP was measured with a new central venous pressure measuring device (mentioned as new method as follows) and a disposable pressure monitoring sensor connecting with monitoring instrument (mentioned as sensor method as follows) by self contrast method. The two methods should be measured at an interval of 3-5 minutes, and the CVP values, required time, material costs, pre- and post-measuring heart rate (HR), mean arterial pressure (MAP) and blood oxygen saturation (SpO2) were collected and compared between the two methods. ResultsThere were no statistically significant differences in CVP values, required time, pre- and post-measuring HR, MAP, SpO2 between the two methods (all P＞0.05); the material costs of the new method were significantly lower than those of the sensor method (P＜0.05). ConclusionThe CVP value measured by the new central venous pressure measuring device is accurate, safe, convenient, and a low cost, which is worthy of clinical promotion.
