Abstract
The supply of N95 respirators has been severely strained by the coronavirus disease 2019 (COVID-19) pandemic. We used quantitative fit-testing to evaluate 16 participants and 45 respirators through up to 4 rounds of ultraviolet decontamination and clinical reuse. The mean fit-test failure rate was 29.7%, and the probability of failure increased through N95 reuse.
摘要
N95 呼吸器的供应因 2019 年冠状病毒病（COVID-19）大流行而严重紧张。我们使用定量贴合测试对 16 名参与者和 45 个呼吸器进行了评估，最多进行了 4 轮紫外线消毒和临床再利用。平均贴合测试失败率为 29.7%，且随着 N95 的重复使用，失败的概率会增加。
