: The current pandemic of novel Corona Virus Disease 2019 (COVID-19) has created a significant shortage of personal protective equipment (PPE) in many countries of the world, stressing medical services during this crisis. Along with addressing problems of demand and supply mismatch, there also a need to ensure the procurement of high-quality PPEs that provides both safety and comfort to users. The purpose of this article is to review existing standards and recommendations on the technical aspects of PPE. : For this review, MEDLINE, Google Scholar, and Research Gate were searched. Studies reporting technical aspects of the components of PPE including mask and respirator, gown, and coverall, gloves, goggles, face shields, or visors, and boots, are included in this review. : The design and materials of PPE needs further research, which might have minimal carriage of infective biological load like the use of antimicrobial repellent finishes along with adequate tensile strength and breathability through the fabric. Respirators should have the least resistance while providing maximum protection; goggles should not have fogging. Also, there is a need of formulating universal technical specifications for medically used PPE and ensuring easy availability of the testing facilities.
当前 2019 年新型冠状病毒病（COVID-19）大流行导致世界许多国家的个人防护设备（PPE）严重短缺，给这一危机中的医疗服务带来压力。除了解决供需不匹配的问题外，还需要确保采购到高质量的 PPE，为使用者提供安全和舒适。本文旨在回顾 PPE 技术方面的现有标准和建议。
为此，我们检索了 MEDLINE、Google Scholar 和 Research Gate。本综述纳入了报告 PPE 组件（包括口罩和呼吸器、长袍和防护服、手套、护目镜、面罩或眼罩以及靴子）技术方面的研究。
PPE 的设计和材料需要进一步研究，例如使用抗菌驱避剂整理剂，同时通过织物保持足够的拉伸强度和透气性，以尽量减少携带感染性生物负荷。呼吸器在提供最大保护的同时应具有最小的阻力；护目镜不应起雾。此外，还需要为医用 PPE 制定通用技术规范，并确保检测设施的便捷可用性。
