The Hudson Non-Rebreather Adult Oxygen Therapy Mask with Reservoir Bag features an elongated oxygen mask moulded of soft transparent PVC plastic.
The flow rate of a non-rebreather mask should be set just high enough to prevent the reservoir bag from collapsing fully when the patient inhales.
A non-rebreather mask is a cheap and effective high concentration oxygen mask that, when used with an oxygen flow rate of 15 litres per minute, can deliver an inspired oxygen concentration of around 70-95%. A standard face mask can only deliver approximately 40-50% O2. So check your O2 kit today and make sure you have a non-rebreather mask.
Why not take your own oxygen mask on your dive trip? In our experience, even though the majority of dive operators now have oxygen equipment of some type, this may not include suitable high concentration non-rebreather oxygen masks.
Sometimes, even if these masks are available, they have been pre-used and are no longer hygienic. They are designed for single use only.
This mask can easily be packed with clothes or dive gear. We believe you should consider taking your own mask on dive trips, just in case it's needed.

On this Hudson Non-Rebreather Adult Oxygen Therapy Mask with Reservoir Bag the tubing adapter swivels to facilitate use on either side of patient. The spandex-terylene adjustable strap ensures a comfortable fit for every patient. The reservoir bag with check valve is constructed of soft vinyl. Comes complete with 2.1 metres (7 foot) of star-lumen oxygen supply tubing. Latex free.
Note: Disposable for single patient use. Not intended for reprocessing.
Non-rebreather masks (NRB) provide a constant high flow of oxygen. The flow rate of an NRB is manually adjustable, and the rate is usually set between 8 and 15 litres per minute. A high flow rate does not necessarily equate to more effective treatment, however. To avoid wasting oxygen, set the flow rate just high enough to prevent the reservoir bag from collapsing fully when the patient inhales. Take care to ensure the mask maintains a good seal for as long as it's used.
Don't set the flow rate lower than 8 to 15 litres per minute in an attempt to make a limited supply of oxygen last longer. Oxygen therapy is used for divers with the goal to create a partial pressure gradient to promote the elimination of inert gas (nitrogen). The way to achieve this goal is to deliver the highest concentration of oxygen possible. Therefore, the priority should be to administer oxygen at the maximum possible concentration until you transfer care, or supplies run out.
Once a diver is on the surface, there is no reason to withhold oxygen. Even if the symptoms noted at depth were actually the result of CNS toxicity, administering oxygen is still recommended, and it will not harm the diver.
Some people mistakenly believe that if a diver is breathing oxygen from a cylinder at surface pressure, air breaks should be used to prevent CNS oxygen toxicity. No air breaks are necessary. Oxygen should be provided without interruption. Air breaks are employed during some hyperbaric-chamber treatments to minimise the risk of CNS toxicity. However, such breaks are not necessary for divers treated at the surface because CNS toxicity is not a concern when the maximum PO2 is 1 ATA.
