Abstract:
Objective To explore the frequencies changing of pressure sensor measuring device suite during central venous pressure( CVP) measurement. Methods A total of 40 patients who required indwelling deep venous catheter and the application of pressure sensor measuring device suite for CVP measurement, were selected as sampling, and the devices connected bedside monitor for CVP measurement twice per day. The frequencies of the suite were changed as every two days, twice per week, once per week, and once every two weeks in order, each way were implemented for four weeks. The flushing water from the connection of deep venous catheter end of the used device was collected to put in asepsis tube for normal bacteria culture, and we compared the positive rate of water bacteria culture with different changing frequencies of suite. Results Under different changing frequencies, there were just two cases presented positive for bacteria culture with positive rate 5. 00% in the changing frequency of once per week. After ruling out the false positive results, flushing water of different changing frequencies were negative for bacteria culture. Conclusions It is safe to utilize pressure sensor measure device suite to measure CVP twice every day and change device once every two weeks.
