Abstract：
UNASSIGNED: Reusable elastomeric half-mask respirators (EHMR) are an alternative to address shortages of disposable respirators. While respirator discomfort has been noted as a barrier to adherence to wearing an N95 filtering facepiece respirator (FFR) among health care personnel (HCP), few have examined EHMR comfort while providing patient care, which was the purpose of this study.
UNASSIGNED: Among a cohort of 183 HCP, we prospectively examined how HCP rated EHMR tolerability using the Respirator Comfort, Wearing Experience, and Function Instrument (R-COMFI) questionnaire at Study Week 2 and Week 10. At the completion of the study (Week-12), HCP compared EHMR comfort with their prior N95 FFR use. Overall R-COMFI scores and three subscales (comfort, wear experience, and function) were examined as well as individual item scores.
UNASSIGNED: The HCP reported an improved overall R-COMFI score (lower score more favorable, 30.0 vs. 28.7/47, respectively) from Week 2 to Week 10. Many individual item scores improved or remained low over this period, except difficulty communicating with patients and coworkers. The overall R-COMFI scores for the EHMR were more favorable than for the N95 FFR (33.7 vs. 37.4, respectively), with a large proportion of workers indicating their perception that EHMR fit better, provided better protection, and they preferred to wear it in pandemic conditions compared with the N95 FFR.
UNASSIGNED: Findings suggest that the EHMR is a feasible respiratory protection device with respect to tolerance. EHMRs can be considered as a possible alternative to the N95 FFR in the health care setting. Future work is needed in the EHMR design to improve communication.

摘要：
■可重复使用的弹性半面罩呼吸器（EHMR）是解决一次性呼吸器短缺的替代方案。虽然呼吸器不适被认为是医护人员(HCP)佩戴N95过滤面罩呼吸器(FFR)的障碍,很少有人在提供患者护理的同时检查EHMR舒适度，这就是本研究的目的。
■在183名HCP中，我们前瞻性地检查了HCP如何使用呼吸器舒适度评估EHMR耐受性，佩戴经验,和功能仪器(R-COMFI)问卷在研究第2周和第10周。在研究完成时（第12周），HCP将EHMR舒适度与之前使用的N95FFR进行了比较。总体R-COMFI评分和三个分量表(舒适度，佩戴经验,和功能)进行了检查以及个别项目得分。
■HCP报告总体R-COMFI得分有所改善（得分越低越好，30.0vs.分别为28.7/47）从第2周到第10周。在此期间，许多个别项目得分提高或保持较低，除了与患者和同事沟通困难。EHMR的总体R-COMFI得分比N95FFR更有利（33.7vs.分别为37.4)，很大一部分工人表示他们认为EHMR更适合，提供更好的保护，与N95FFR相比，他们更喜欢在大流行条件下佩戴它。
■研究结果表明，就耐受性而言，EHMR是一种可行的呼吸保护装置。EHMR可以被认为是医疗保健环境中N95FFR的可能替代方案。在EHMR设计中需要未来的工作来改善通信。
