Non-Rebreather Mask (NRB)
Description
A Non-Rebreather Mask (NRB) is a medical device used for oxygen therapy. It allows for the delivery of high concentrations of oxygen to patients who are able to breathe unassisted. Unlike low-flow oxygen devices (such as nasal cannulas), the NRB is designed with a reservoir bag and one-way valves to prevent rebreathing of exhaled carbon dioxide, ensuring patients receive higher oxygen concentrations.
Key Features
- Delivers high oxygen concentration (60–100%)
- Includes a reservoir bag for oxygen storage
- One-way valves to prevent rebreathing of exhaled gases
- Adjustable elastic strap for secure fit
- Transparent design for easy patient monitoring
- Single-use, disposable, and latex-free construction

FAQs
1. When is a non-rebreather mask used?
It is used in medical emergencies or acute care settings where patients need high oxygen delivery, such as in cases of hypoxia, trauma, or respiratory distress.
2. Can patients breathe without assistance when using an NRB?
Yes. The NRB requires the patient to be able to breathe spontaneously, as it does not provide mechanical ventilation.
3. How much oxygen can the NRB deliver?
The NRB can deliver up to 100% oxygen, depending on the fit, reservoir inflation, and oxygen flow rate.
4. Is the NRB mask reusable?
No, NRB masks are designed for single-use only and should be disposed of after use to maintain hygiene and safety.
5. What is the difference between an NRB and a simple oxygen mask?
A simple mask delivers lower oxygen concentrations (35–55%) without a reservoir, whereas an NRB delivers higher oxygen concentrations (60–100%) thanks to its reservoir bag and one-way valves.
