Methods: This study is bibliographical, descriptive, and analytical in nature. POCUS-related publications published were downloaded from the Web of Science (WoS)database and analyzed using statistical methods. Network visualization maps wereused to identify trending topics. Results: The literature search revealed 5714 publications on POCUS in the WoSdatabase. According to the WoS categorization of publications, the most commoncategories were emergency medicine (1751; 30.6%). The topics studied in recentyears were deep learning, artificial intelligence, COVID-19, acute kidney injury, heartfailure, and telemedicine. Conclusion: This study on POCUS, we summarized 5714 publications published.According to our results, the trending topics in POCUS research in recent yearsinclude deep learning, artificial intelligence, COVID-19, acute kidney injury, heart fail-ure and telemedicine. Our study can be a valuable resource for clinicians and scien-tists who are working on POCUS or will be working on POCUS in the future.
