Abstract:
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.
