Non-Rebreather Mask

Non-Rebreather Mask (NRB Mask)/ Oxygen Reservoir Bag 1. Reservoir bag with one-way valve – Attached to the mask, the reservoir bag stores 100% oxygen from the source. A one-way valve between the mask and bag prevents exhaled air from entering the bag, ensuring the patient inhales only fresh, high-concentration oxygen. 2. Exhalation ports with flutter valves (side flaps) – Located on both sides of the mask, these one-way valves open during exhalation to release exhaled carbon dioxide and close during inhalation to prevent room air from being drawn in, minimizing air entrainment. 3. Soft, contoured mask with metal nose clip – Made of soft PVC or silicone, the mask conforms to facial contours for a snug seal. An adjustable metal nose clip helps secure the fit and reduce oxygen leakage around the nose bridge.
