A nasal cannula typically delivers FiO2 in which range?

Explanation:
FiO2 from a nasal cannula is limited by mixing oxygen with room air as the patient inhales. With typical adult flow rates of about 1–6 L/min, the delivered FiO2 is generally in the low to mid‑20s up to the low 40s percent range. In other words, it increases as you raise the flow, but it usually stays around 24–40% and rarely approaches higher percentages. If a higher FiO2 is needed—around 60% or more—a different delivery method such as a mask or another system is used.
