气道廓清技术研究的可视化分析

Visual analysis of airway clearance technology research

目的分析气道廓清技术的相关文献,了解气道廓清技术的发展趋势、研究热点。方法检索Web of Science核心数据库气道廓清技术相关文献,检索时限为2000年1月1日—2023年8月31日;采用Origin 2022、Scimago Graphica、VOSviewer 1.6.18、CiteSpace 6.2.4软件进行可视化分析。结果共纳入2553篇文献,2000—2023年气道廓清技术相关文献发文量呈波动上升趋势。美国的发文量位居世界首位;Chang是发文量最多的作者。研究机构主要集中在美国、中国、澳大利亚等国家的高校,其中悉尼大学发文量最多。研究热点主要集中在气道廓清障碍的疾病类型、气道廓清技术类型、气道廓清技术重点人群和实施场所等方面。结论气道廓清技术的发文量呈持续增长趋势。未来我国学者可加强跨学科和跨地域交流,以提高该领域研究的深度和广度。

ObjectiveTo analyze the research on airway clearance technology,explore the trends,and research hotspots for airway clearance technology.MethodsThe literature on airway clearance technology was searched in the Web of Science core database.The search period was from January 1,2000,to August 31,2023.Origin 2022,Scimago Graphica,VOSviewer 1.6.18,and CiteSpace 6.2.4 software were used for visualization analysis.ResultsA total of 2553 articles were included,and the number of articles on airway clearance technology showed a fluctuating upward trend from 2000 to 2023.The United States ranked first in the world in terms of publication volume.Chang was the author with the highest number of publications.Research institutions were mainly concentrated in universities in countries such as the United States,China,and Australia,with the University of Sydney having the highest publication volume.The research hotspots mainly focused on types of airway clearance disorders,types of airway clearance techniques,key populations and implementation sites for airway clearance.ConclusionsThe number of publications on airway clearance technology continues to increase.It is necessary to strengthen interdisciplinary and cross-regional exchanges and enhance the depth and breadth of research by Chinese scholars.
