Bibliometric analysis reveals a growing interest in end-tidal carbon dioxide (EtCO2) research, with key focus areas including monitoring methods and applications in various diseases. Increased international collaboration is recommended to advance the field.
Area of Science:
- Medical research
- Physiology
- Biomedical engineering
Background:
- End-tidal carbon dioxide (EtCO2) monitoring is crucial in clinical practice.
- Understanding research trends in EtCO2 is essential for advancing its applications.
- Previous bibliometric analyses have not comprehensively mapped the EtCO2 research landscape.
Purpose of the Study:
- To conduct a bibliometric and visual analysis of EtCO2 literature.
- To identify current research hotspots and development trends in EtCO2.
- To provide insights for future basic research and clinical applications of EtCO2.
Main Methods:
- Comprehensive literature search across Web of Science core collection databases (SCI-EXPANDED, SSCI, CPCI-Science).
- Bibliometric analysis of publication output, authorship, and collaboration networks.
- VOSviewer software utilized for visualization of authors, journals, countries, institutions, and keywords.
Main Results:
- A total of 4442 EtCO2 publications were analyzed, showing a consistent increase in output.
- The United States, United Kingdom, and Canada lead in publications; University of Toronto, University of British Columbia, and Harvard University are top institutions.
- Key research areas include EtCO2 definition, monitoring methods, indices, and applications in diseases like obstructive sleep apnea.
Conclusions:
- Growing publication numbers indicate increasing research interest and a mature level in the EtCO2 field.
- Established international cooperation provides a strong foundation for future collaborative efforts.
- Enhanced interdisciplinary collaboration, funding support, and literature quality are recommended to further advance EtCO2 research.
