What is a common flow rate for nasal cannula oxygen delivery?

• A. 5-10 liters per minute
• B. 1-6 liters per minute
• C. 10-15 liters per minute
• D. 15-20 liters per minute

Answer: (B)

A common flow rate for nasal cannula oxygen delivery is typically between 1 to 6 liters per minute. This range is widely accepted in clinical settings because it allows for effective oxygenation while minimizing the risk of discomfort or complications associated with higher flow rates. At these lower flow rates, the nasal cannula can efficiently deliver supplemental oxygen to patients with mild to moderate respiratory distress without overwhelming them. Excessively high flow rates can lead to issues such as mucosal drying or discomfort. Thus, the range of 1 to 6 liters per minute is often the standard for providing supplemental oxygen using a nasal cannula, making it suitable for many patients' needs.
