We are in a crisis where healthcare providers on the frontlines are running out of the appropriate personal protective equipment including N95 masks and power air-purifying respirators. Here, we propose a makeshift filter mask that we call the Modified Airway from VEntilatoR Circuit (MAVerIC) that can be assembled within seconds using widely available supplies routinely utilized by anesthesia providers in the operating room to provide practitioners on the frontlines with the high standard of protection of a N95 mask during the coronavirus disease 2019 (COVID-19) pandemic, and can be easily quantitatively "fit tested" to ensure no significant leak to optimize safety and efficacy.

我们正处于一场危机之中，一线医护人员的适当个人防护装备，包括N95口罩和电动空气净化呼吸器即将耗尽。在此，我们提出一种简易过滤口罩，我们称之为“呼吸机回路改良气道口罩（MAVerIC）”，它可以在几秒钟内组装完成，使用手术室麻醉人员常规使用的广泛可得的用品，在2019冠状病毒病（COVID-19）大流行期间为一线从业者提供N95口罩的高标准防护，并且可以轻松地进行定量“适合性测试”，以确保无明显泄漏，从而优化安全性和有效性。
