The indoor environment of a mechanically ventilated hospital building controls infection rates as well as influences patients' healing processes and overall medical outcomes. This review covers the scientific research that has assessed patients' medical outcomes concerning at least one indoor environmental parameter related to building heating, ventilation, and air conditioning (HVAC) systems, such as indoor air temperature, relative humidity, and indoor air ventilation parameters. Research related to the naturally ventilated hospital buildings was outside the scope of this review article. After 1998, a total of 899 papers were identified that fit the inclusion criteria of this study. Of these, 176 papers have been included in this review to understand the relationship between the health outcomes of a patient and the indoor environment of a mechanically ventilated hospital building. The purpose of this literature review was to summarize how indoor environmental parameters related to mechanical ventilation systems of a hospital building are impacting patients. This review suggests that there is a need for future interdisciplinary collaborative research to quantify the optimum range for HVAC parameters considering airborne exposures and patients' positive medical outcomes.
医院建筑的室内环境不仅可以控制感染率，还会影响患者的愈合过程和整体医疗效果。本综述涵盖了评估患者医疗效果的科学研究，这些研究至少涉及与建筑供暖、通风和空调（HVAC）系统相关的一个室内环境参数，如室内空气温度、相对湿度和室内空气通风参数。与自然通风医院建筑相关的研究不在本文综述的范围内。1998 年以后，共确定了 899 篇符合本研究纳入标准的论文。其中，有 176 篇论文被纳入本综述，以了解患者健康状况与机械通风医院建筑室内环境之间的关系。本文综述的目的是总结与医院建筑机械通风系统相关的室内环境参数是如何影响患者的。本综述表明，未来需要开展跨学科合作研究，在考虑空气传播暴露和患者积极医疗效果的情况下，量化 HVAC 参数的最佳范围。
