High-flow nasal cannula oxygen and non-invasive ventilation with passive humidification are compared. The study questions whether these respiratory support methods are truly comparable, impacting critical care medicine practices.
Area of Science:
- Critical Care Medicine
- Respiratory Therapy
Background:
- High-flow nasal cannula (HFNC) oxygen and non-invasive ventilation (NIV) with passive humidification are common respiratory support modalities.
- The optimal choice between HFNC and NIV for specific patient populations remains a subject of ongoing clinical debate.
