空气净化系统对医院手术部空气净化效果分析

目的了解南平市部分医院洁净手术部空气净化系统技术性能及其对空气的净化效果。方法采用现场采样方法对洁净手术部空气中的尘埃粒子、沉降菌、换气次数、静压差及其他微小气候等进行检测。结果创建初期，5所医院的洁净手术部各项指标均符合相应等级的国家标准。使用2年后，Ⅰ级洁净手术室平均尘埃粒子数合格率为80.0%，相对湿度合格率为60.0%，其它项目合格率为100%。所有房间的沉降菌和温度的合格率为100%，尘埃粒子数合格率为85.7%，换气次数合格率为78.4%，相对湿度合格率为89.3%，噪声合格率为91.1%，照度合格率为75.0%，静压差合格率为89.3%。结论南平市部分医院洁净手术部存在空气净化系统综合性能减弱，部分技术指标不合格，管理不到位等情况，必须加强对空气净化系统的日常维护和管理，才能确保其对洁净手术部空气的净化效果。

Efficacy of air-purifying system on purifying air of operating department in hospital

Objective To find out the technical properties of air-purifying system of some hospitals in Nanping and its efficacy on purifying the air of operating department.Methods On-the-spot air sampling method was used to examine the dust particle count,settling bacteria count,ventilation frequency,differential pressure and microclimate of the air.Results At the early stage,all the indexes of the operating departments in the five hospitals were in compliance with the national standard in the corresponding grade.Aft...
