The aim of the study was to valuate effectiveness of the air condition system in hospitals. It was done by estimation of bacteria and fungi concentration in the air. The study were performed in ten hospital rooms which were protected by EU 13 or EU 9 filters. Possible the most important source of fungi was not treated air incoming from outside. Only in four of the rooms concentrations of the fungi in the air were satisfactory and not exceeded 20 cfu/m3 (cfu--colony forming unit). However in two of them the number of fungi rise 4-5 times after the windows were opened. Concentration of the fungi in operating theater number 2 (1-2 cfu/m3) allow to valuate efficiency of air conditioning systems. The lowest bacteria concentration was in Intensive Care Unit (73 cfu/m3) but the highest in instrumentalists rum (1427 cfu/m3. where according to high fungi concentration (116 cfu/m3) the air conditioning systems was switched of and the ventilation was by open windows.
该研究的目的是评估医院空调系统的有效性。这是通过估计空气中细菌和真菌的浓度来完成的。该研究在十个由欧盟13级或欧盟9级过滤器保护的医院病房中进行。真菌最重要的可能来源是从外部进入的未处理空气。只有四个房间的空气中真菌浓度令人满意，未超过20 cfu/m³（cfu——菌落形成单位）。然而，其中两个房间在窗户打开后真菌数量增加了4至5倍。2号手术室的真菌浓度（1至2 cfu/m³）有助于评估空调系统的效率。细菌浓度最低的是重症监护室（73 cfu/m³），但最高的是器械室（1427 cfu/m³），那里由于真菌浓度高（116 cfu/m³），空调系统被关闭，通风通过打开窗户进行。
