World is fighting one of its greatest battle against COVID-19 (a highly infectious disease), leading to death of hundreds of thousands of people around the world, with severe patients requiring artificial breathing. To overcome the shortage of ventilators in medical infrastructure, various low-cost, easy to assemble, portable ventilators have been proposed to fight the ongoing pandemic. These mechanical ventilators are made from components that are generally readily available worldwide. Such components are already associated with day-to-day gadgets or items and which do not require specialized manufacturing processes. Various designs have been proposed, focussing on meeting basic requirements for artificial ventilation to fight the ongoing pandemic. But some people are against the usage of these mechanical ventilators in real-life situations, owing to poor reliability and inability of these designs to meet certain clinical requirements. Each design has its own merits and demerits, which need to be addressed for proper designing. Therefore, this article aims to provide readers an overview of various design parameters that needs to be considered while designing portable ventilators, by systematic analysis from available pool of proposed designs. By going through existing literature, we have recognized multiple factors influencing device performance and how these factors need to be considered for efficient device operation.
全世界正在与新冠肺炎（一种高传染性疾病）进行一场最为艰巨的战斗，这场战斗已导致全球数十万人死亡，重症患者需要人工呼吸。为克服医疗基础设施中呼吸机短缺的问题，人们提出了各种低成本、易于组装且便于携带的呼吸机来应对当前的疫情。这些机械呼吸机由在全球范围内普遍容易获取的部件制成。此类部件已应用于日常小工具或物品中，且不需要专门的制造工艺。人们已经提出了各种设计方案，重点是满足人工通气的基本要求以应对当前的疫情。但由于可靠性差以及这些设计无法满足某些临床要求，一些人反对在实际情况中使用这些机械呼吸机。每种设计都有其优缺点，在进行合理设计时需要加以解决。因此，本文旨在通过对现有一系列已提出的设计进行系统分析，为读者提供在设计便携式呼吸机时需要考虑的各种设计参数的概述。通过查阅现有文献，我们已经认识到影响设备性能的多个因素以及为实现设备高效运行如何考虑这些因素。
