What fi02 can be delivered with a nasal cannula on a pediatric patient?

A nasal cannula can deliver an approximate FiO2 (fraction of inspired oxygen) of 24% to 40% in pediatric patients, depending on the flow rate used. Typically, flow rates of 1 to 6 liters per minute are employed, with higher flow rates yielding higher FiO2 levels. However, the exact FiO2 can vary based on the patient's respiratory pattern and the presence of any supplemental oxygen. It's important to monitor the patient's response and adjust the flow rate as needed.
