Abstract

Respiratory protective equipment (RPE) is in high demand during epidemics and pandemics. The SARS-CoV-2 pandemic has demonstrated that the global industry had insufficient capacity for providing people with high-efficiency respirators. In this context, it is important to assess the protective properties of equipment designed to prevent the spread of infections. In this review, the hydrodynamic and filtering characteristics of modern RPE types present in the market, as well as their consumer performance, are analyzed taking into account the properties of virus-bearing aerosols. Approaches to developing novel, more efficient fiber-based RPE are proposed.

SARS-CoV-2大流行中呼吸防护设备的效率

摘要

在流行病和大流行期间，呼吸防护设备 (RPE) 的需求量很大。SARS-CoV-2 大流行表明，全球工业没有足够的能力为人们提供高效呼吸器。在这种情况下，重要的是评估旨在防止感染传播的设备的保护特性。在这篇综述中，考虑到携带病毒的气溶胶的特性，分析了市场上现代 RPE 类型的流体动力学和过滤特性，以及它们的消费者性能。提出了开发新颖、更有效的基于纤维的 RPE 的方法。
