Which device can deliver flow rates up to 15 L/min?

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

Answer: (C)

High Flow Nasal Cannula is designed to deliver heated, humidified oxygen at higher flow rates, far exceeding standard nasal cannulas or simple masks. This higher flow helps meet the patient’s inspiratory demand, reduces rebreathing of exhaled gas, and allows more stable, controllable FiO2. Because of its capability to push much higher flows, it can reach around 15 L/min, which is beyond what the other devices typically provide. Standard nasal cannulas max out around 6 L/min, simple masks usually stay in the lower to mid-range, and Venturi masks deliver precise oxygen concentrations but are not primarily used for the highest flow levels.
