Lung ultrasound (LUS) is gaining recognition as an indispensable diagnostic tool in critical care.
The study aimed to characterize the global research landscape and trend of LUS with quantification and visualization approaches.
Documents related to LUS published between 2007 and 2023 were selected from the Web of Science Core Collection and identified. Visualization and statistical analysis were conducted with the VOSviewer 1.6.18, CiteSpace 5.7.R5, and Bibliometrix 4.1.0 Package, including analysis of the trend of global publications, prominent countries, active institutions, and funding agencies, key authors and journals, co-cited references, and keywords.
A total of 3010 publications, including 2434 articles and 576 reviews, were retrieved. The output of LUS-related research has increased steadily over the years, especially after 2018. Italy (n=756; 25.12%) has shown the highest output, being the country with the highest total citations (23423 times). The most influential author was Gargani Luna with 52 documents, who worked at the Consiglio Nazionale delle Ricerche. Chest and Intensive Care Medicine with high citations and impact factor scores were the most influential journals. Besides "lung ultrasonography", the keywords developed included "coronavirus disease 2019 (COVID-19)", "acute respiratory distress syndrome", and "acute heart failure".
Research output on LUS has increased steadily, especially after 2018. Italy and the United States are staying ahead in this field. Research collaboration still needs to be strengthened. This comprehensive analysis has presented the global research landscape and trends of LUS-related research, providing valuable information for researchers to pursue further exploration.
肺部超声（LUS）在重症监护中作为一种不可或缺的诊断工具正逐渐得到认可。
本研究旨在通过量化和可视化方法描述LUS的全球研究格局和趋势。
从Web of Science核心合集中选取并识别2007年至2023年期间发表的与LUS相关的文献。使用VOSviewer 1.6.18、CiteSpace 5.7.R5和Bibliometrix 4.1.0软件包进行可视化和统计分析，包括对全球出版物趋势、主要国家、活跃机构和资助机构、关键作者和期刊、共被引参考文献以及关键词的分析。
共检索到3010篇出版物，其中包括2434篇文章和576篇综述。多年来，LUS相关研究的产出稳步增长，尤其是在2018年之后。意大利（n = 756；25.12%）的产出最高，是总被引次数最高的国家（23423次）。最有影响力的作者是Gargani Luna，发表了52篇文献，其工作单位是意大利国家研究委员会。被引次数和影响因子得分较高的《胸部》和《重症医学》是最有影响力的期刊。除了“肺部超声检查”外，出现的关键词还包括“2019冠状病毒病（COVID - 19）”、“急性呼吸窘迫综合征”和“急性心力衰竭”。
LUS的研究产出稳步增长，尤其是在2018年之后。意大利和美国在该领域领先。研究合作仍需加强。这项综合分析呈现了LUS相关研究的全球研究格局和趋势，为研究人员进行进一步探索提供了有价值的信息。
