Standard Nasal Cannula delivers lower flows of O2 from __________ to __________ L/min.

Explanation:
A standard nasal cannula is a simple, low-flow oxygen delivery device. It provides modest amounts of oxygen, so the typical delivery range is 1 to 6 L/min. At lower flows, you’d get less supplemental O2 and more room air mixing; at higher flows within this range, the patient receives a higher fraction of inspired oxygen while remaining comfortable and humidified. Flows below 1 L/min aren’t standard for this device, and flows above about 6 L/min start to require different delivery systems designed for higher FiO2. That’s why 1–6 L/min is the correct range.
