Clinicians who care for patients infected with coronavirus disease 2019 (COVID-19) must wear a full suite of personal protective equipment, including an N95 mask or powered air purifying respirator, eye protection, a fluid-impermeable gown, and gloves. This combination of personal protective equipment may cause increased work of breathing, reduced field of vision, muffled speech, difficulty hearing, and heat stress. These effects are not caused by individual weakness; they are normal and expected reactions that any person will have when exposed to an unusual environment. The physiologic and psychologic challenges imposed by personal protective equipment may have multiple causes, but immediate countermeasures and long-term mitigation strategies can help to improve a clinician's ability to provide care. Ultimately, a systematic approach to the design and integration of personal protective equipment is needed to improve the safety of patients and clinicians.
照顾 2019 冠状病毒病（COVID-19）感染者的临床医生必须穿戴全套个人防护设备，包括 N95 口罩或动力空气净化呼吸器、眼部防护、防体液渗透的长袍和手套。这种个人防护设备的组合可能会导致呼吸工作增加、视野缩小、言语模糊、听力困难和热应激。这些影响不是由个体虚弱引起的；它们是任何暴露在不寻常环境中的人都会产生的正常和预期反应。个人防护设备带来的生理和心理挑战可能有多种原因，但即时应对措施和长期缓解策略有助于提高临床医生的护理能力。最终，需要采取系统的方法来设计和整合个人防护设备，以提高患者和临床医生的安全性。
