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. No-rebreathing masks are frequently used in areas such as A&E departments for trauma patients.
