Oximizer AND high flow nasal cannulas deliver flow rates from ____-____ L/min.

Oximizer AND high flow nasal cannulas deliver flow rates from ____-____ L/min.

• A. 0-5 L/min
• B. 1-15 L/min
• C. 5-10 L/min
• D. 10-20 L/min

Answer: (B)

Understanding how much gas can be delivered helps you tailor oxygen therapy to a patient’s needs without overdoing flow. The Oximizer and high-flow nasal cannulas are both adjustable devices, and in this course their typical operating range is presented as starting near 1 L/min and can be titrated up to about 15 L/min. This range covers the low-to-moderate flow settings at which many patients can be comfortably managed while achieving the desired increase in oxygen delivery. Remember, real high-flow systems can push much higher than 15 L/min in other contexts, but for this item the focus is on the lower-to-moderate end that these devices are commonly set to in practice.
