Patients Comfort During Highflow Oxygen Therapy With Asymmetrical Prongs

High-flow nasal cannula (HFNC) is a respiratory support device widely used to manage acute respiratory failure (ARF) and recommended in different patient populations according to the last European Respiratory Society and European Society of Intensive Care Medicine guidelines. HFNC delivers heated and humidified oxygen that facilitates airway secretion clearance, and its use is associated with improvement of oxygenation and reduction of airway dead space compared to standard oxygen therapy. Finally, all these beneficial effects result in a greater comfort experienced by the patient, as compared either to standard oxygen therapy or non-invasive ventilation.
