Randomized Controlled Trial
Heated and humidified high-flow oxygen therapy reduces discomfort during hypoxemic respiratory failure.
Non-intubated critically ill patients are often treated by high-flow oxygen for acute respiratory failure. There is no current recommendation for humidification of oxygen devices. ⋯ Upper airway caliber was not significantly modified by HHFO₂, compared to standard oxygen therapy, but HHFO₂ significantly reduced discomfort in critically ill patients with respiratory failure. The system is usually preferred over standard oxygen therapy.
