What is the typical maximum flow rate for a non-rebreather mask?

A non-rebreather mask is designed to deliver a high concentration of oxygen to patients who are in respiratory distress or require significant oxygenation. The typical maximum flow rate for a non-rebreather mask is generally set between 10 to 15 liters per minute. This flow rate ensures that the reservoir bag of the mask is adequately filled, which allows the patient to receive a higher concentration of oxygen, typically around 60% to 100% depending on the patient's respiratory status and the fit of the mask.

When the flow rate is set within this range, it minimizes the risk of exhaled air mixing with the oxygen in the reservoir, thus providing a more efficient oxygen delivery system. If flow rates are set too low, the patient may not receive enough oxygen, while flow rates above 15 liters per minute, such as those mentioned in the other options, do not significantly increase the concentration of oxygen delivered to the patient and can result in wastage.
