Which oxygen device is heat and humidified high-flow nasal cannula system?

• A. Oxymizer
• B. Standard Nasal Cannula
• C. High Flow High Humidity Nasal Cannula
• D. Venturi Mask

Answer: (C)

Delivering heat and humidity with high flow through a nasal cannula means providing heated, fully humidified gas at a high flow rate via a nasal cannula interface. This setup both warms and moistens the inspired gas to body conditions and delivers it at flows that can meet or exceed the patient’s inspiratory demands. The result is improved mucociliary function, airway comfort, and reduced dead space, which helps lower the work of breathing and can support oxygenation in hypoxemic patients. The device that does this best is a high-flow nasal cannula system designed to deliver heated, humidified gas at high flow rates along with adjustable oxygen concentration. The other options don’t fit because they either focus on conserving oxygen with a reservoir, provide only low-flow oxygen, or deliver a fixed FiO2 with a mask rather than through a heated, humidified nasal interface.
