The non-rebreathing mask (sometimes called a Hudson mask) has an oxygen reservoir bag and is used to deliver high concentrations of oxygen to a spontaneously breathing patient. A one-way valve diverts the oxygen flow into the reservoir bag during expiration. The contents of the reservoir bag together with the high flow of oxygen result in minimal entrainment of air and an inspired oxygen concentration of approximately 85%. The valve also prevents exhaled gases from entering the reservoir bag.
The use of the oxygen reservoir bag helps to increase the inspired oxygen concentration by preventing oxygen loss during inspiration.
Consists of:
Oxygen tube 14 Fr x 150 cm, x2 Adaptor ID 14 Fr, non-rebreathing mask with elastic strap, and reservoir bag
Intended Use
A non-rebreathing mask is a medical device that helps deliver oxygen in emergency situations. It consists of a face mask connected to a reservoir bag that is filled with a high concentration of oxygen. The reservoir bag is connected to an oxygen tank. The mask covers both your nose and mouth. One-way valves prevent exhaled air from re-entering the oxygen reservoir.
A non-rebreathing mask is used in emergency situations to prevent hypoxemia or low blood oxygen. Conditions that disrupt your lungs’ ability to uptake oxygen or your heart’s ability to pump blood can cause low blood oxygen levels.
It is important to ensure that a sufficient oxygen flow rate is used so the oxygen reservoir bag does not collapse during inspiration; a flow rate of 12-15 L/min is recommended.
Some non-rebreathing masks have elasticated ear loop bands. As these eliminate the need to move the patient’s head, they are used frequently in A&E departments for trauma patients.
Please note that this device shall only be used by a well-trained and qualified healthcare person or under supervision of a physician in hospital or clinical settings.
