■COVID-19爆发后,对空气传播病毒感染的兴趣增加了。我们考虑了通过在将病毒吸入暖气之前灭活病毒来降低感染其他人的风险的方法,通风,和空调(HVAC)系统。我们在一所三级大学医院新改建的门诊中安装了最近开发的空气消毒器,并确认了其有效性。
■在重南国立大学医院改建了耳鼻喉科门诊后,15KOKKOS空气消毒器(BentechFrontierCo.,Ltd.,光州,韩国)已安装。在安装前三天,在五个单独的检查区域测量了总的可培养微生物(TCM)和挥发性有机化合物(VOCs)。安装后2周,安装后4周。
■测量TCM后,除检查区域5外,所有时间点空气消毒器安装后2周,空气质量均有改善,4周后进一步改善(p<0.05).经过VOCs的评估,空气消毒器连接后4周,所有时间点都有改善(p<0.05)。
■KOKKOS空气消毒器可有效改善三级大学医院门诊的空气质量。
UNASSIGNED: After the COVID-19 outbreak, interest in airborne virus infections has increased. We considered ways to reduce the risk of infection to other people by inactivating the virus before it is inhaled into the heating, ventilation, and air conditioning (HVAC) systems. We installed a recently developed air sterilizer in the newly remodeled outpatient clinic of a tertiary university hospital and confirmed its effectiveness.
UNASSIGNED: After remodeling the ENT outpatient clinic at Chonnam National University Hospital, 15 KOKKOS air sterilizers (Bentech Frontier Co., Ltd., Gwangju, Korea) were installed. Total culturable microorganisms (TCMs) and volatile organic compounds (VOCs) were measured in five separate inspection areas three days before installation, 2 weeks after installation, and 4 weeks after installation.
UNASSIGNED: After measurement of TCMs, improvement in air quality occurred 2 weeks after air sterilizer instatement at all timepoints except inspection area 5, and further improvement was achieved after 4 weeks (p < 0.05). After assessment of VOCs, improvement occurred 4 weeks after air sterilizer connection at all points (p < 0.05).
UNASSIGNED: KOKKOS air sterilizers are effective in improving air quality in an outpatient clinic at a tertiary university hospital.
