Standalone Anti-aspyxiation valves

Full face masks, hybrid masks, and oral masks have anti-asphyxiation valves. If the power goes off, you can breathe fresh air without removing the mask. On the Oracle oral mask, it's a separate piece that fits on the end of the hose, but it won't fit on a standard nasal mask.

Does anyone make an anti-asphyxiation valve that fits between the mask and the hose? That way, you'd get fresh air with a nasal mask even if the power goes off.

I think this part would work, except the fittings are for the wrong end of the hose and it wouldn't work if you put it on the mask end.

I understand that hospital-style cpap masks do not have the valve built in; and thus the valve needs to be elsewhere.
Hospital supply places?

No, I'm using the mask in my profile, not a hospital mask.

If such a thing would exist it would be great! It is quite easy to invent... I wonder if and when some company will make it.

You could modify the valve or make an adapter.

The Oracle's, Forma's and Flexifit's antiasphyxia valve are all the same part. You can take the valve out of the elbow piece and put it in the Opus.

You can isert the valve at the end of the hose (right side) instead of the swivel connector.

The none rebreathing valve is made to open at a certified pressure per code. The one- way valve that you mention is probably not made to this standard. Otherwise , you could use a water pipe and put some chashish in it.



Does it not Stand Alone?

The other night I sneezed into my F&P #431 mask and blew off the none rebreathing valve leaves. Luckily, I have also the #432 mask from which I borrowed the valve. The next day I fixed those leaves with a pair of twizers.

Ozie is right in this case:

Yes, that's the right idea, except that it doesn't fit between a normal mask and hose. One end is "normal," but the other end isn't. The right angle also makes it a little difficult to use.

If you look closely at the end of this product ( see below ) the anti-asphyxia valve is a separable piece.
The right end fits a normal CPAP hose but the left end is slightly different. It's not so much so that one would have great difficulty in adapting it.

I just checked my Oracle 2 mask and easily detached the valve and then replaced it. To make it adapt to something else, I's suggest the infamous "Duck Tape" in your choice of colors.

ozij posted above a different part but it sure looks like the valve is exactly the same and should be removable like on the Oracle 2 mask tubing.

Isn't this doing what you want?

Take a caliper and check the diameters of the parts.

Archangle,
I assume this sentence "You can take the valve out of the elbow piece " was not clear enough.

The elbow (right angle piece) and the anti-asphyxia valve are two different parts. As JSS74 said, you can pull them apart.

You are then left with an elbow in one hand, and the anti-asphyxia valve in the other.

You can check the mask manuals and the F&P parts catalog for confirmation.

Yes, I know, thanks.

I took the anti-asphyxia valve out of my oracle mask before I started this thread and even with the right angle piece removed, the connectors don't match up to connect it between the mask and the hose. If I leave the right angle piece in, those connectors don't match up either. I don't have the mask handy right now, but I'll look at it again later and see if I missed anything.

Duct tape isn't a very practical solution because it would be a problem when I clean the mask. It didn't look like an adapter would be very convenient to make and use, but I'll take a look at it again and see if anything looks like it would be practical.

I'm a PC tech that just got a CPAP recently, so I can't comment on parts, dimensions, and fittings. But I might have a solution, http://www.newegg.com/Product/Product.a ... 6842102117 A battery backup (UPS) will give you power for a brief blackout, and it's warning tone would wake you up before it runs out of power. It's rated to power a full desktop PC (Monitor & Tower) for about 8 minutes, but I imagine it would last significantly longer with a CPAP because of the discrepancy in power drain.

Archangel, I think that you make a bit of a fuss about this issue. To start with, it is not called anti-asphyxiation valves but non-rebreathing valves. You would not get asphyxiated during power stoppage b/c CPAP masks have intentional leak holes. But you would breathe air a bit higher with CO2.

About your question: Does anyone make an anti-asphyxiation valve that fits between the mask and the hose? That way, you'd get fresh air with a nasal mask even if the power goes off. Why if you use a nasal mask can't you just open your mouth to breathe in such cases?
