ABSTRACT
Respirators are important personal protective equipment to reduce the exposure of respiratory tract infections in health care workers (HCW). It is important to choose suitable respirators through fit testing and wear them correctly. This article introduced the classification of respirators and summarized the purposes, methods and requirements of fit testing, as well as the challenges when performing it. Users can choose the suitable respirators including powered air-purifying respirators and tight-fitting facepiece only when they passed fit testing. Qualitative fit testing (QLFT) and quantitative fit testing (QNFT) assays were two categories of fit testing and studies showed that the effect of QNFT in the detection of leaks was better than that of QLFT. Users should perform fit checking everytime in order to wear the respirator correctly although the respirators were screened by fit testing before. It was difficult to implement fit testing during the COVID-19 pandemic because of the shortage of respirator supply. But now domestic and foreign institutions have re-emphasized the supervision of respirator fit testing as the supply of respirators resumes. Although the fit testing of respirators needs the support of clinical technical systems and faces various cost challenges, it not only has high education value but also provides effective protection for the HCW in medical institutions.
