Guidelines for heating, ventilation, and air-conditioning systems have been developed for different settings. However, there is a lack of up-to-date evidence providing concrete recommendations for the heating, ventilation, and air-conditioning systems of an isolation room, which is essential to appropriately guide infection control policies. To highlight the guidelines for heating, ventilation, and air-conditioning systems in isolation rooms to inform relevant stakeholders and policymakers. A systematic search was performed based on Joanna Briggs Methodology using five databases (CINAHL, Embase, Joanna Briggs Institute, Medline, and Web of Science) and websites. Eight articles published by government departments were included in this review. Most studies recommended controlled airflow without recirculation, 12 air changes per hour, high-efficiency particulate air filtrate to exhaust contaminated air from the airborne isolation room, humidity ≤60%, and temperature in the range of 18-30 °C. This review provides further evidence that there is a need for interdisciplinary collaborative research to quantify the optimum range for heating, ventilation, and air conditioning system parameters, considering door types, anterooms, and bed management, to effectively reduce the transmission of infection in isolation rooms.
针对不同场所，已经制定了供暖、通风和空调系统指南。然而，对于隔离病房的供暖、通风和空调系统，缺乏最新的具体建议，这对于适当指导感染控制政策至关重要。本研究旨在强调隔离病房供暖、通风和空调系统指南，为相关利益攸关方和决策者提供信息。基于 Joanna Briggs 方法学，通过五个数据库（CINAHL、Embase、Joanna Briggs 研究所、Medline 和 Web of Science）和网站进行了系统检索。本综述纳入了 8 篇政府部门发表的文章。大多数研究建议采用无再循环的控制气流、每小时 12 次空气交换、高效微粒空气过滤，将受污染的空气从空气传播隔离病房中排出，湿度≤60%，温度在 18-30°C 之间。本综述进一步证明，需要开展跨学科合作研究，量化供暖、通风和空调系统参数的最佳范围，同时考虑门的类型、前室和床位管理，以有效降低隔离病房的感染传播。
