Humidified high flow nasal airway respiratory support

Humidified high flow nasal airway respiratory support is a method of delivering a high per-minute volume of respiratory gas via nasal cannula; and thus a medical device in health processing. "Nasal high flow is a promising novel oxygen delivery device, whose mechanisms of action offer some beneficial effects over conventional oxygen systems. The administration of a high flow of heated and humidified gas mixture promotes higher and more stable inspiratory oxygen fraction values, decreases anatomical dead space and generates a positive airway pressure that can reduce the work of breathing and enhance patient comfort and tolerance."
