HFNC offers several benefits: - Comfort: It is more comfortable than traditional oxygen masks and reduces the feeling of claustrophobia. - Humidification: The heated humidification prevents drying of the nasal passages and maintains mucociliary function. - High Flow Rates: It can deliver oxygen at higher flow rates, ensuring adequate oxygenation in patients with severe respiratory conditions. - Reduced Work of Breathing: By delivering a high flow of oxygen, it helps in reducing the effort required to breathe, which is crucial for critically ill patients.
