Abstract

Due to the airborne transmission of the coronavirus disease 2019 (COVID 19) via aerosols or microdroplets, this study investigated the effect of a mobile air filter system in a surgical examination room. The use of the air filter system led to a significant reduction of aerosols in the room. Therefore the use of a high efficiency air filtration device, in examination rooms with poor ventilation, e.g. lack of windows or local exhaust, is mandatory.

摘要

由于2019冠状病毒病(COVID-19)通过气溶胶或微滴进行空气传播,本研究调查了移动空气过滤系统在外科检查室中的效果。空气过滤系统的使用使室内气溶胶显著减少。因此,在通风不良的检查室,如没有窗户或局部排风的情况下,必须使用高效空气过滤装置。
