If so, there are many problems with this mask. It will get you through, in a pinch, but the O2PTIMASK
TM is SO much easier to use, without most of the pitfalls of the mask in the picture above.
Now look at THIS mask:

In the first picture, you notice where the mask fits up to the face, there is just an edge of plastic to fit. This does NOT give an airtight seal, especially if he has any facial hair. If you look at the second picture, notice the red around the edge of the mask. This is an air filled chamber, that forms VERY well to the contours of the face, and gives a MUCH better seal.
If you look back at the first picture, you notice the two round white seals on each side of the mask. These are air valves that are suppose to seal when you inhale, and then release when you exhale. MANY masks only have the flapper seal on one side, and the other just has holes. These are notoriously prone to letting in outside air, keeping him from getting 100% oxygen.
If you look at the second picture, you notice that there are no vent holes on the sides of the mask. The valving and venting are all done in the green "T" valve assembly. These seals are much more secure, and do not fail as often or as fast as the ones on the side of the first pictures valves.
In the first picture, you do not see the full bag, but it is small, only about 1 liter in capacity. The second picture shows the whole bag, it is deep green. This is a much larger bag, that holds about 3 liters of oxygen. For each deep inhale that he does, during oxygen therapy, he will inhale between 2 and 3 liters of oxygen. The bigger bag allows for that, where the smaller one does not. He will be emptying the bag for each inhale.
The first picture is called a "disposable" mask. Not that you would dispose of it, after only one use, but it gives you a hint of the quality of the whole mask and its components. They are not designed for repeated or long term usage.
The mask in the second picture is design with heavier material, and longer lasting components. The whole thing can be easily disassembled for cleaning.
Using the O2PTIMASK
TM (the second picture) gives a much quicker abort time, and last a lot longer. Most people that have tried them, swear by them.
Does that answer your questions?
