Which device delivers 2-6 L/min flow?

The essential idea here is low-flow oxygen delivery. A nasal cannula is designed to deliver oxygen at relatively low flows, typically from about 1 to 6 liters per minute, mixing with room air as it enters the nasal passages. This makes it the device used when a patient needs a modest increase in oxygen without a high, fixed flow. Nebulizers deliver medication as a mist and aren’t defined by a specific oxygen flow for delivery; the driving gas flow is not primarily about providing a fixed 2-6 L/min of oxygen. A non-rebreather mask is a high-flow device that usually requires about 10–15 L/min to keep the reservoir filled and achieve high oxygen concentrations. CPAP provides continuous positive airway pressure and isn’t described by a fixed low flow like 2–6 L/min; the flow is managed to maintain pressure, and varies with the patient.
