Q

Nasal cannula <5L/min conversion to fio2

A

1 L/min flow rate can increase FiO2 to 24%,
2 L/min to 28%,
3 L/min to 32%,
4 L/min to 36%,
5 L/min to 40%,
and 6 L/min to 44%.

This may be changing, new studies say inspiration flow rate has a greater impact on fio2 than NC flow rate for low flow O2 delivery
