Non-Rebreather Mask

     Non-Rebreather Mask

   It is a medical device used to deliver high concentrations of oxygen to individuals who are experiencing severe respiratory distress or oxygen deprivation. It is typically used in emergency or hospital settings when a patient requires immediate and high-flow oxygen support. The mask is designed to allow the patient to inhale almost pure oxygen while preventing the rebreathing of exhaled air, which can improve oxygenation quickly.

Key Features and Components:

1. Mask Design: The non-rebreather mask covers the nose and mouth, and it is made of soft, flexible material for a secure fit. It is usually transparent to allow healthcare providers to monitor the patient’s condition.

2. Oxygen Reservoir Bag: One of the defining features of an NRB is the attached reservoir bag, which is typically inflated with oxygen before being placed on the patient. This bag holds a reservoir of oxygen, ensuring that a high concentration of oxygen is available during inhalation.

3. One-Way Valves: The mask includes one-way valves that prevent exhaled air from entering the reservoir bag or being re-breathed by the patient. This ensures that the patient is receiving a high concentration of oxygen and not their own exhaled carbon dioxide.

4. High Flow Rate: Non-rebreather masks are designed for high oxygen flow rates, typically around 10-15 liters per minute (LPM). This high flow allows for quick and efficient delivery of oxygen, making it suitable for emergency situations.

5. Adjustable Straps: The mask has adjustable straps that help ensure a secure and comfortable fit over the patient’s nose and mouth, reducing air leakage and improving the effectiveness of the oxygen delivery.
