|
0-6 L/min
|
|
|
6-30 L/min

Explanation:
Detailed explanation-1: -Therefore, a nasal cannula set at 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%.
Detailed explanation-2: -Flow rates of 1-4 litres per minute are used with nasal cannulas, equating to a concentration of approximately 24-40% oxygen.
