预计席卷地球仪大部分地区的COVID-19疫情持续时间不会很短，应急计划显示其可能会持续至少18个月。在美国，应对这一流行病的关键问题之一是地方、州和国家各级缺乏必要的个人防护设备。由于COVID-19主要通过呼吸途径传播，因此充分的呼吸保护是非常必要的。近年来，从耐用和可重复使用的医疗用品转向一次性用品，降低了医疗系统在当前大流行中对个人防护设备和其他关键用品的弹性。本研究从所需等效防护装置数量的角度，探讨了可重复使用呼吸防护装置与一次性使用呼吸防护装置相比在当前大流行中的作用，包括一次性使用选项的再处理。文献的当前状态也进行了审查，以提供这项工作的背景下，就资源采购。在整个流行病的PPE的经济成本进行了探讨，它被发现，利用可重复使用的PPE选项取决于过滤器循环可能成本较低。废物产生的增加是当前流行病的另一个问题，这是利用质量基础进行探索的，发现可重复使用的呼吸PPE比在业务照常情况下使用一次性PPE产生的废物更少。由于COVID-19未来的爆发可能会沿着其他未来的大流行病，这项工作提供了如何从PPE的角度做好准备的见解，特别是呼吸防护。
The COVID-19 pandemic sweeping much of the globe is not anticipated to be short in duration, with contingency plans suggesting that it may last at least eighteen months. In the United States, one of the critical issues in coping with the pandemic has been a lack of essential personal protective equipment (PPE), at the local, state, and national level. As COVID-19 is primarily transferred through respiratory routes, adequate respiratory protection is a dire necessity. The shift from durable and reusable medical supplies in recent years to their single use counterparts has reduced the resiliency of the medical system with respect to PPE and other critical supplies in the current pandemic. This work explores the role of reusable compared to single use respiratory protection in the current pandemic, including reprocessing of single use options, from the perspective of number of equivalent protection devices needed. The current state of literature is also reviewed to provide context to this work, with respect to resource procurement. The economic cost of PPE throughout a pandemic is explored, and it is found that utilizing reusable PPE options depending on filter cycling may be less costly. Increased waste production is another issue with the current pandemic, and this is explored utilizing a mass basis, finding that reusable respiratory PPE would generate less waste than using single use PPE in a business as usual scenario. As future outbreaks of COVID-19 are likely along with other future pandemics, this work provides insights at how to prepare from the standpoint of PPE, and in particular respiratory protection.
