Which oxygen delivery method uses a flow of 6-8 LPM?

• A. Nebulizer
• B. Nasal Cannula
• C. Non-Rebreather Mask
• D. Bag Valve Mask

Answer: (A)

The device that uses a flow of 6-8 L/min is the nebulizer. Nebulizers rely on a steady gas flow to convert liquid medication into a fine aerosol that the patient can inhale, and the typical driving flow is around 6-8 liters per minute. Other common oxygen delivery methods operate at different typical rates: a nasal cannula usually delivers up to about 6 L/min, a non-rebreather mask typically requires 10-15 L/min to maintain a high FiO2 with a full reservoir, and a bag-valve mask needs even higher flows (often 15 L/min or more) during manual ventilation. Thus, the 6-8 L/min range specifically matches the nebulizer.
