Clinical Report: Bibliometric Assessment of High-Flow Nasal Oxygen Utilization
Overview
This bibliometric analysis reveals significant growth in high-flow nasal oxygen (HFNO) research, particularly post-2018.
Background
High-flow nasal oxygen (HFNO) is a vital noninvasive respiratory support method in critical care and perioperative settings, improving oxygenation while ensuring patient comfort.
Data Highlights
The analysis included 2,314 unique publications from 2000 to 2025, showing exponential growth in HFNO research.
Key Findings
HFNO research has accelerated significantly since 2018, particularly after 2020.
The primary contributors to HFNO literature are the United States and China.
Major research clusters include acute respiratory failure, perioperative oxygen therapy, and preoxygenation strategies.
There is a notable shift in focus from perioperative applications to broader critical care contexts.
Current research emphasizes context-specific deployment and monitoring.
Clinical Implications
Understanding the latest trends and evidence in HFNO research can inform clinical decision-making.
Conclusion
HFNO research has transitioned into a diverse field with significant implications for clinical practice.
