摘要

改善医院环境中的室内空气质量(IAQ)可以保护脆弱的患者和医疗保健专业人员免受空气污染物和病原体的侵害。本研究整合了三个相互关联的组成部分:医院室内空气质量的综合分析,纳米银/壳聚糖-二氧化钛(纳米银/CS-TiO2)过滤器的评估,以及使用基于云的平台的实时监测评估。纳米ag /CS-TiO2过滤器在减少广泛的污染物方面表现出更高的效率,包括颗粒物(PM2.5和PM10)、一氧化碳、二氧化碳、挥发性有机化合物(VOCs)和微生物气溶胶。在不同的医院区域和时间范围内进行了测量,以反映典型的医院业务,并评估拟议解决方案的适应性。该研究进一步解决了纳米ag /CS-TiO2的长期使用问题,并强调了其相对于现有过滤方法的优势。基于云的监测提供实时数据,可以及时干预室内空气质量,特别是在负压隔离室等高风险地区。在负压隔离室中发现,安装纳米ag /CS-TiO2过滤系统后,室内空气质量显著改善。纳米ag /CS-TiO2过滤和实时监测的集成支持符合世界卫生组织(WHO)室内空气质量标准。这些发现强调了在各种医疗保健环境中广泛应用的潜力,例如门诊诊所和急诊科。该研究还确保了污染物检测的准确性,解决了基于云的监测中可能出现的假阳性和阴性。本研究强调纳米ag /CS-TiO2过滤系统可以通过有效去除空气污染物和灭活空气中的病原体来提高医院环境中的室内空气质量。这种方法有助于制定以证据为基础的战略,促进医院室内环境的健康。

Improving Hospital Air Quality With a Nano-Ag/Chitosan-TiO2 Filter System and Cloud-Based Monitoring

Improving Hospital Air Quality With a Nano-Ag/Chitosan-TiO2 Filter System and Cloud-Based Monitoring

Improving indoor air quality (IAQ) in hospital environments protects vulnerable patients and healthcare professionals from airborne pollutants and pathogens. This study integrates three interconnected components: a comprehensive analysis of hospital IAQ, an evaluation of a nanosilver/chitosan–titanium dioxide (nano-Ag/CS-TiO2) filter, and an assessment of real-time monitoring using a cloud-based platform. The nano-Ag/CS-TiO2 filter demonstrated enhanced efficiency in reducing a broad spectrum of pollutants, including particulate matter (PM2.5 and PM10), carbon monoxide, carbon dioxide, volatile organic compounds (VOCs), and microbial aerosols. Measurements were conducted across different hospital zones and timeframes to reflect typical hospital operations and assess the adaptability of the proposed solutions. The study further addresses the long-term use of nano-Ag/CS-TiO2 and underscores its advantages over existing filtration methods. Cloud-based monitoring provides real-time data, allowing for timely intervention for IAQ, particularly in high-risk areas like negative pressure isolation rooms. The finding in a negative pressure isolation room demonstrated significant improvement in IAQ postinstallation of the nano-Ag/CS-TiO2 filtration system. The integration of nano-Ag/CS-TiO2 filtration and real-time monitoring supports compliance with World Health Organization (WHO) IAQ standards. These findings highlight the potential for broader application in various healthcare settings, such as outpatient clinics and emergency departments. The study also ensures accuracy in pollutant detection, addressing the potential for false positives and negatives in cloud-based monitoring. This study highlights that a nano-Ag/CS-TiO2 filtration system can enhance IAQ in hospital settings by effectively removing air pollutants and inactivating airborne pathogens. This approach facilitates the development of evidence-based strategies for promoting healthier indoor environments in hospitals.

期刊介绍: The quality of the environment within buildings is a topic of major importance for public health. Indoor Air provides a location for reporting original research results in the broad area defined by the indoor environment of non-industrial buildings. An international journal with multidisciplinary content, Indoor Air publishes papers reflecting the broad categories of interest in this field: health effects; thermal comfort; monitoring and modelling; source characterization; ventilation and other environmental control techniques. The research results present the basic information to allow designers, building owners, and operators to provide a healthy and comfortable environment for building occupants, as well as giving medical practitioners information on how to deal with illnesses related to the indoor environment.
