Which oxygen delivery regimen uses either 6 liters per minute via nasal cannula or 12 liters per minute via face mask?

• A. High flow oxygen
• B. Nasal cannula
• C. Venturi mask
• D. Nebulized oxygen

Answer: (A)

In oxygen therapy, different devices deliver oxygen at different flow rates and with different levels of control over the delivered concentration. A nasal cannula can deliver oxygen at up to about 6 liters per minute, while a simple face mask can push higher flows, typically around 6 to 12 liters per minute depending on the mask and the fit. The regimen described—providing 6 L/min through a nasal cannula or 12 L/min through a face mask—points to a high-flow approach, where the system is capable of delivering relatively high volumes of oxygen to meet the patient’s inspiratory demands, regardless of the interface. Other options don’t fit this pattern: a nasal cannula is a basic delivery method limited to lower flows; a Venturi mask delivers a precise FiO2 but relies on a specific flow range and is not defined by a single higher-flow value; nebulized oxygen is about aerosolized delivery for medications, not a high-flow oxygen strategy. So, the description matches high-flow oxygen therapy.
