No anti-asphyxiation valve on pillow masks?
I have a P10 nasal pillow mask, and noticed there isn't an anti-asphyxiation valve like there is on full-face masks.
The resistance through the mesh is fairly high, so if say the hose were to come off from the CPAP machine, it seems like you could end up breathing almost completely the same air over and over again. I'm concerned because this seems somewhat dangerous.
Has anyone had any experience with this?

You don't need it on a pillow mask...you can open your mouth and breathe in the event of a power failure. You can't do that with a ff mask.

Mask designs are engineered to accommodate almost any situation.
Practically the only way a mask could cause harm is if it is used incorrectly.
I hate when people do that.

Re: No anti-asphyxiation valve on pillow masks?
I actually just went and tested my P10 mask...with the hose not attached to the machine I could breathe easily as the air coming in from the hose was quite sufficient to be comfortable.
Now once I put my hand over the hose to block the incoming air (simulating a power outage) then things got more difficult in terms of inhaling and exhaling using only the vent holes. It was uncomfortable and there is no doubt that if I lost power and had no air moving that I would either wake up or simply just open my mouth and breath that way.
Now a while back I did this same experiment with the Swift FX nasal pillows..those vent holes are larger...and I found that in the event of a power outage and no air moving in the hose that I was okay just using those vent holes for air movement.
So if it really bugs you as to what might happen in the event of a power outage...you might look at the Swift FX nasal pillows.
With either one though if the hose comes loose from the machine there's going to be enough air coming in and out of the hose to avoid any discomfort or problems with rebreathing as long as the hose isn't blocked.

Re: No anti-asphyxiation valve on pillow masks?
If the machine goes off, you can continue to breathe though the vent holes. It will not be comfortable and so you will wake up. The system is designed to work this way. You can not suffocate even if the machine goes off. There isn't a "valve" as the mask has a constant vent.
But you have got yourself worried about this, so you can buy a cheap emergency light with alarm at amazon for $13. You plug it into the wall and if the power goes out, the battery powered alarm and light come on. It's very loud. Here's the link: http://www.amazon.com/Powerout-Power-Fa ... 00IA9BF70/

Re: No anti-asphyxiation valve on pillow masks?
no, if the machine goes off, you'll breath through the machine, up and down the hose, which will mean a LOT of co2.yaconsult wrote:If the machine goes off, you can continue to breathe though the vent holes. It will not be comfortable and so you will wake up. The system is designed to work this way.
the assumption is that you'll breath through your mouth, as others have said.
ALL masks have a constant vent, yet, manufacturers see the need to put an anti-asphixyation valve on any mask that covers the nose AND mouth.
think.

Last week in Whitehorse the power went off at 3:30am. I woke up instantly due to the extra work of breathing.

Re: No anti-asphyxiation valve on pillow masks?
We've been sleeping with the windows open, and sometimes whatever's in the air stuffs up my nose to the point where I can't get any air in through my nose.
I'm here to tell you there IS an anti-asphyxiation valve on nasal pillow masks--it's called your mouth.

Re: No anti-asphyxiation valve on pillow masks?
Yesterday, I used the Panasonic oral irrigator ("water pic" by another name) and distilled water
on the mesh in my P10. It made quite a difference--got it cleaner than a toothbrush (which leaves them gray)--
I can actually feel the air flowing more easily. Now I have to do the same to my older P10's.

hmm, never thought of that... last time I cleaned 'em, I used an old brushhead on my electric toothbrush, and a bit of dish soap... seemed to work great.chunkyfrog wrote:Yesterday, I used the Panasonic oral irrigator ("water pic" by another name) and distilled water

Re: No anti-asphyxiation valve on pillow masks?
Thanks for this link, yaconsult. For those of us whose power goes out a fair amount, having something like that would be reassuring. One never knows how quickly one will wake up or start breathing through our mouths when the power goes out.yaconsult wrote:you can buy a cheap emergency light with alarm at amazon for $13.

Re: No anti-asphyxiation valve on pillow masks?
You are welcome. It does work well and is cheap enough. You can turn the audible alarm on or off as you wish.
I have not been using mine but now that I'm taping my mouth, maybe I should reconsider it... I can breathe through the micopore tape if the machine goes off, but the resistance is high enough that I'm sure it would wake me up.
I think our brains somehow know that the air from the cpap is important. More than once, I have suddenly found myself wide awake the instant the machine stopped working.

Re: No anti-asphyxiation valve on pillow masks?
I use a full face mask, and I have woken up quickly anytime the power has gone out. Or the cat has stepped on the power button. (The cat is still standing there when I wake up).
I can breathe through the mask with the valve open, but it is enough of a reduction that I notice it pretty quickly. I would think that most people would notice it quickly, regardless of which type of mask they are using.

Re: No anti-asphyxiation valve on pillow masks?
I've noticed that when we have a power loss I deflate and fly around like a balloon... thats enough to wake me up...
