HFNC (high-flow nasal cannula) is a respiratory care device used for oxygen therapy. A high flow of warm and humidified air is developed through nasal cannulas to patients suffering from respiratory distress.
HFNC therapy is used for treating patients with acute hypoxemic respiratory failure. It helps to improve breathing by preventing inflammation of airway passage. It provides relief and comfort to patients by reducing the work of breathing. HFNC can deliver flow rate up to 60 liters per minute of oxygen.
