Inside hospitals, there is a trend of increasing levels of air pollutants. However, only the indoor air quality in operating theaters is carefully monitored. Therefore, we set the goal of this study to evaluate the indoor air quality in areas of an orthopedics department and to compare the indoor air quality indices that characterize these areas. We used a monitoring system based on the Internet of Things with uRADMonitor model A3 sensors, with which we prospectively measured indoor air quality in the facilities of the orthopedic emergency hospital of Targu Mures in Romania, between 1 February 2023, and 31 January 2024. The primary target pollutants investigated in the emergency room, outpatient room and ward were carbon dioxide (CO), nitrogen dioxide (NO), volatile organic compounds (VOCs) and particles with a diameter smaller than 2.5 μm (PM2.5). We compared the effectiveness of the intervention for emergency rooms where air purifiers were working or not. The concentrations of CO, VOCs and PM2.5 were significantly higher in the emergency room than in the outpatient room or ward. The indoor air quality was worst in winter, when the CO, NO and VOC concentrations were at their highest. Air purifiers can help reduce the concentration of PM2.5 in emergency rooms. Medical staff and patients in orthopedic hospitals, especially in emergency rooms, are frequently exposed to polluted ambient air, which can affect their health. Orthopedic medical practice guidelines should address issues relating to the protection of personnel through the application of measures to improve indoor air quality.
在医院内部，空气污染物水平呈上升趋势。然而，只有手术室的室内空气质量受到严格监测。因此，我们设定了本研究的目标，即评估骨科部门各区域的室内空气质量，并比较表征这些区域的室内空气质量指标。我们使用了基于物联网的监测系统以及uRADMonitor A3型传感器，据此对罗马尼亚特尔古穆列什骨科急诊医院在2023年2月1日至2024年1月31日期间的室内空气质量进行了前瞻性测量。在急诊室、门诊室和病房中调查的主要目标污染物为二氧化碳（CO）、二氧化氮（NO）、挥发性有机化合物（VOCs）和直径小于2.5微米的颗粒物（PM2.5）。我们比较了空气净化器运行或未运行的急诊室的干预效果。急诊室中CO、VOCs和PM2.5的浓度显著高于门诊室或病房。冬季室内空气质量最差，此时CO、NO和VOC浓度最高。空气净化器有助于降低急诊室中PM2.5的浓度。骨科医院的医护人员和患者，尤其是急诊室的人员，经常暴露于受污染的环境空气中，这可能会影响他们的健康。骨科医疗实践指南应通过采取改善室内空气质量的措施来解决与人员保护相关的问题。
