高净化:“高净化”指示灯亮时,风机全速运行,房间内达到至高净化等级和至大温度调节效果。即ICU病房净化系统处于“高净化级别状态”,能达到洁净ICU病房设计的净化级别。
低净化:“低净化”指示灯亮时时,风机低速运行,房间内维持清洁和适当温度,洁净ICU病房处于“低净化级别状态”,不能达到洁净ICU病房设计的净化级别,如万级ICU病房设计级别为万级,在选择低净化级别时不能达到万级净化室标准。
值班运行:洁净ICU病房维持一定的正压,保证室内不受外界污染。
2. 层流设备
2. laminar flow equipmentICU的防污染要求比较高,因为在ICU中,各种继发性疾病常引起呼吸衰竭,icu净化,病人须紧急气管切开、紧急开胸等手术,也包括正常术后病人的复苏,因此,净化工程安装,在现 代ICU病房设计时要考虑使用层流净化设施,减少感染机率。ICU内温度应维持在24±1.5℃;老年患者病房温度在25.5℃左右。Anti pollution requirements of ICU is relatively high, because in ICU, various secondary diseases often cause respiratory failure, the patient must emergency tracheotomy and emergency thoracotomy surgery,icu, including the patient's normal po*toperative recovery, therefore, in the modern design of the ICU ward to consider when using the laminar flow purification facilities, reduce the risk of infection. The temperature in ICU should be maintained at 24 + 1.5; the temperature of the elderly patients in the ward is about 25.5.
