AbstractThe objective of this analysis was to explore the research hotspot of coronavirus disease 2019 (COVID-19) mechanical ventilation. The literature related to COVID-19 mechanical ventilation on PubMed and CNKI database of core journals was retrieved with the keyword of COVID-19 mechanical ventilation. The visualisation software of VOS (visualisation of similarities) viewer performed by the authors and high-frequency keywords. A total of 524 English language articles from PubMed and 81 Chinese literature from China National Knowledge Infrastructure (CNKI) of core journals are included in this paper. The two databases produced six research fields, among which much attention was paid to the prevention of nosocomial infection and antiviral agents in the treatment of mechanical ventilation. The literature yeilded by PubMed paid attention to the factors affecting the poor prognosis of mechanically ventilated patients, the management and research and development of medical data during COVID-19's pandemic, the mechanical ventilation treatment of COVID-19 pregnant women, the mechanical ventilation treatment and nursing in the field of CNKI literature research, and the nutritional treatment of severe pneumonia patients with mechanical ventilation. The current COVID-19 researches, focused on the prevention of nosocomial infection and antiviral drugs in the process of mechanical ventilation, are a new hotspot in the world. Key Words: Coronavirus disease 2019 (COVID-19), Mechanical ventilation, Research hotspot, VOSviewer, Visual analysis.
