【摘要】 目的探讨ICU层流病房空气质量影响因素及管理对策。方法采用平板暴露采样法,对不同人员数及活动状态、不同湿度、回风口过滤网不同清洗时间的细菌菌落数进行对比研究。结果①相对静止状态细菌菌落数少于活动状态时,两组有显著性差异(P<0.05)。②在不同湿度状态下湿度控制在40%~50%和50%~70%两组对比细菌菌落数差异无显著性(P>0.05)。③清洗回风口过滤网后第7、14、21、28d采样,结果过滤网清洗时间细菌菌落数无显著性差异(P>0.05)。结论对ICU进行科学的工作流程和管理是保持室内空气洁净的有效方法。更多还原

【Abstract】 Objective To investigate the influencing factors and the strategy of administration of air quality in ICU lamina flow ward. Methods using the method of flat plate exposure sampling to contrast the bacteria colonies in different patients and active conditions, different humidity, different cleaning time of wind gap filtrator . Results ① the two groups have significant differences (P<0.05),when the bacteria colonies from relative stationary state group were lower than active condition group(P<0.05). ②The bacteria colonies haven’t great difference,when the humidity was controlled between 40%～50% and 50%～70% (P>0.05). ③The bacteria colonies were similar (P>0.05) , sampling in 7th ,14th ,21st ,28th days after cleaning the wind gap filtrator. Conclutions It is an effective method of running and managing the scientific work flow in ICU for keeping the air clean.更多还原
