What is the flow rate for a Non-Rebreather Mask (NRB)?

The flow rate for a Non-Rebreather Mask (NRB) is typically set at 12-15 liters per minute. This higher flow rate is crucial because it allows for the delivery of a significant amount of oxygen to the patient, ensuring that they receive an adequate concentration of oxygen while minimizing the chance of room air mixing in. The NRB is designed to deliver nearly 100% oxygen as it has a one-way valve that prevents exhaled air from entering the bag and thereby diluting the oxygen supply.

When administering oxygen using an NRB, the goal is to achieve optimal oxygen saturation levels, particularly in cases of respiratory distress or hypoxemia. The 12-15 liters per minute flow rate is considered effective for achieving this high concentration of oxygen delivery, making it essential to use the appropriate flow rate to ensure patient safety and treatment efficacy. This is why the correct answer reflects this specific flow rate range.
