High Concentration Mask + non rebreathing bag | Paediatric

High Concentration PVC Non Rebreathing Oxygen Mask Non-Rebreathing Masks and High Concentration Oxygen Masks with a reservoir bag are used to deliver high concentrations of oxygen. A one-way valve allows oxygen to be delivered to the reservoir bag during expiration and minimises air entrainment during inspiration to achieve a high oxygen concentration. The valve also prevents exhaled gases from entering the reservoir bag. The reservoir bag helps to increase the inspired oxygen concentration by reducing oxygen loss during inspiration.
