目的 探讨影响冷凝水感染程度的相关因素,为临床护理呼吸机管道、减少冷凝水感染提供参考依据.方法 选择辽宁医学院附属第一医院ICU使用呼吸机的80例患者作为研究对象,采用相关和回归分析方法,研究影响冷凝水感染的相关因素,并建立回归模型.结果 呼吸机管路中冷凝水感染程度与管道长度(r=0.837,P＜0.01)、病室与管道中气体的温度差(r=0.875,P＜0.01)、呼出气体的湿度(r=0.793,P＜0.01)、通气量(r=0.932,P＜0.01)均存在相关性;但在多元回归分析过程中,管道长度不能进入回归方程(t=-0.09,P＞0.05),其回归方程为y=-168.08+9.96x1(病室与管道中气体的温度差)+0.33x2(湿度)+20.98x3(通气量).结论 管道长度、病室与管道中气体的温度差、呼出气体的湿度和通气量是影响冷凝水感染程度的相关因素,医护人员可以考虑从相关因素着手来控制冷凝水的感染.
目的 探討影響冷凝水感染程度的相關因素,為臨床護理呼吸機管道、減少冷凝水感染提供參攷依據.方法 選擇遼寧醫學院附屬第一醫院ICU使用呼吸機的80例患者作為研究對象,採用相關和迴歸分析方法,研究影響冷凝水感染的相關因素,併建立迴歸模型.結果 呼吸機管路中冷凝水感染程度與管道長度(r=0.837,P＜0.01)、病室與管道中氣體的溫度差(r=0.875,P＜0.01)、呼齣氣體的濕度(r=0.793,P＜0.01)、通氣量(r=0.932,P＜0.01)均存在相關性;但在多元迴歸分析過程中,管道長度不能進入迴歸方程(t=-0.09,P＞0.05),其迴歸方程為y=-168.08+9.96x1(病室與管道中氣體的溫度差)+0.33x2(濕度)+20.98x3(通氣量).結論 管道長度、病室與管道中氣體的溫度差、呼齣氣體的濕度和通氣量是影響冷凝水感染程度的相關因素,醫護人員可以攷慮從相關因素著手來控製冷凝水的感染.

Objective To explore the related factors influencing the condensate infection level in order to provide a reference for ventilator pipe care and reducing condensate infections.Methods A total of 80 patients using ventilator in ICU of the First Hospital of Liaoning Medical University was chosen as the research object,and the related factors influencing the condensate infection using correlation and regression analysis method were explored,and the regression model was estabhshed as well.Results Condensate infection were correlated with pipe length (r=0.837,P＜0.01),temperature difference between ward and gas in the pipe (r=0.875,P＜0.01),exhaled gas humidity (r=0.793,P＜0.01) and ventilation (r=0.932,P＜0.01),but the pipe length could not enter the regression equation (t=-0.09,P＞0.05),and the regression equation was y=-168.08 +9.96x1 (temperature difference) +0.33x2 (exhaled gas humidity) +20.98x3 (ventilation).Conclusions Pipe length,temperature difference between ward and gas in the pipe,exhaled gas humidity and ventilation were the influencing factors,and medical personnel can control the infection of condensate considering the influencing factors.
