摘要
目的:通过与机械通气病人套囊压力专用测压表所测压力的比较,探讨一次性换能器在套囊压力测定方面的应用价值。方法:将96例重症监护室(ICU)机械通气病人随机分成两组,分别用专用测压表及换能器测量患者套囊压力及套囊容积进行比较。结果:两组呼吸机检查均不漏气,一次性换能器组套囊充气容积(7.51±1.15)mL,测得压力值(21.09±1.97)mmHg(1 mmHg=0.133 kPa);压力表组套囊充气容积(7.25±1.15)mL,测得压力值(21.32±2.58)mmHg,套囊充气容积及测得压力值两组间比较差异(P>0.05)均无统计学意义。结论:一次性换能器测压法是一种简单易行,准确可靠、成本低廉的科学、理想的方法,可以应用于临床测量机械通气病人套囊压力。
Objective： To compare the differences of special cuff pressure meter and disposable transducer in measuring cuff pressure of patients undergoing mechanical ventilation,and to explore the applied value of disposable transducer.Methods： 96 patients in ICU undergoing mechanical ventilation were randomly divided into two groups,and measured cuff pressure by special cuff pressure meter and disposable transducer respectively.Results： The aerocyst volume of disposable transducer group was（7.51±1.15）mL and the aerocyst pressure was（21.09±1.97）mmHg,While the aerocyst volume of special cuff pressure meter group was（7.25±1.15）mL and the aerocyst pressure was 21.32±2.58mmHg.There was no significance difference in volume and pressure of aerocyst between the two groups.Conclusion： Disposable transducer is a simply,accurate and cheap measuring meter,we can use it in clinic to measure the aerocyst pressure of patients undergoing mechanical ventilation.
