Application of non-humidified low flow nasal oxygen inhalation in ICU patients / 现代临床护理

ABSTRACT

Objective To investigate the afflication of non-humidified low flow nasal oxygen inhalation in the ICU patients. Methods Four hundred patients hospitalized in ICU and needing continuous low-flow oxygen inhalation for more than 24 h were randomly divided into experiment group and control group equally.The experiment group were managed with dried humidification bottle oxygen inhalation and the control group conventional humidified bottle oxygen inhalation.The two groups were compared in terms of 24 h respiratory reactions,bacterial contamination of the humidified bottle,complaints of patients about oxygen inhalation noises and time for nurses to change the humidified bottles.Results The two groups had no significant difference in adverse symptoms(all P>0.05).The rate of bacterial contamination in the experimental group was significantly lower than the control group(P<0.05),the noises were lower and the time for changing the bottle shorter(P<0.05).Conclusion Non-humidified low flow nasal oxygen inhalation in ICU patients is good for reducing the rate of bacterial contamination of humidified bottle and lowering workload and oxygen-inhaling noises.
