Study Notes
High Flow Nasal Cannula (HFNC)
- HFNC stands for High Flow Nasal Cannula.
- A characteristic feature of HFNC therapy is the delivery of heated and humidified oxygen at a high flow rate (typically 10-60 liters per minute).
- HFNC is most commonly utilized in patients with acute respiratory distress syndrome (ARDS).
- HFNC provides the advantage of improving oxygenation and ventilation compared to standard oxygen therapy.
- A potential disadvantage of HFNC is the risk of nasal mucosal irritation due to the high flow rate and humidity.
