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

A non-rebreather mask needs a high oxygen flow to keep the reservoir bag inflated and to minimize drawing in room air during inhalation. Delivering oxygen at a rate in the 10–15 L/min range ensures the bag stays full and the patient receives a high concentration of oxygen, typically around 60–90% depending on how well the mask fits and the patient’s breathing. If the flow is too low, the reservoir deflates and the patient ends up inhaling more ambient air, reducing the FiO2. Flow at rates well above what the device is designed for isn’t necessary and can be uncomfortable, so the standard range is used.
