Mask venting air flow over eyes all night long
#1
Anyone else have problems with this? I gave up on a mask I could have lived with otherwise due to this issue. Have a pre-existing eye problem that this exacerbated greatly. I see people report it as an issue at times--but it's often impossible to find out where the vents are placed in masks until you hold them in your hands and look right at them. Really rather go with a hybrid or very small mask rather than a full face one that fits over the whole nose--but what the DME handed me as a replacement was a full face model that is taking some time to get used to.

All masks have exhaust vents. Some of them have more diffuse exhaust flows that others. Two masks that I'm very familiar with that have diffuse exhaust flows are the Resmed AirFit P10 nasal pillows mask and the F&P Eson nasal mask---if you use the optional filter on the exhaust port.

Another choice is to use an eye mask of some sort to cover the eyes. That's usually enough to keep the airflow from hitting the eyes.

I agree that this is a terrible problem for someone with eye problems. I have chronic dry eye and use Restasis for it, but I still can't tolerate a mask sending any air towards my eyes.

I just started using xPAP therapy in the winter. The first mask I tried, a nasal mask called "Pico", vented its exhaust straight at my eyes and my mouth. What a terrible design!

I have a Wisp nasal mask now. It vents to the side. It usually doesn't bother my eyes at all unless it leaks, which it did a couple of nights ago, causing me to wake up with my eyes feeling like those little pickled white cocktail onions.

The mask is leaking now because it's time to replace its nasal cushion, which I'll be doing as soon as the one I ordered arrives. I have been using it for two months and it has been fine.

An eye mask can be a good solution if you can get one to fit well enough to protect your eyes at the bottom. I have not been able to do that with the two nasal masks I have tried so far (Pico and Wisp).

I plan to try a nasal pillows design next and I imagine I'll be dealing with the same issue, but I'm hoping there will be room for the eye mask to fit properly with nasal pillows.

Is it venting air or leaking air? Two different things. Venting air is what we mean when air leaves the mask on purpose as it is designed. Leaks are just that, air leaking from the mask between your skin and the mask.

If the mask is leaking at the top of your nose, blowing into your eyes, there are a few things you can do to lessen or eliminate that. This is a common problem with full face masks. You can try a liner such as the Remzzz liners or the Gecko. You can try to nestle the mask lower on your face. The Simplus, the mask I use, prefers to sit this way.

You can also use gel eye drops at night to prevent your eyes from drying out. That's what I do. I've seen more lubricating eye drops advertised as being "for night use" because of how they absorb into and coat the eye.

Thanks for all the replies. I initially had some leaks and was able to mostly eliminate those, so the problem is venting. The venting on that model is not great for this at all--not many vent holes and they are on top of the mask, pointing straight up--so the air flow through them is fairly fast and it washes right in front of the eyes.

I may have an alternate solution though. I liked the small size and feel of the mask I had, but the DME gave me a new mask, Redmed Airfit F10 I think--to try. It's a full face mask, with many vent holes in a circle around the hose attachment location. So far I think it's no longer a problem--the flow out the vents is more diffuse and not as strong, and it heads out away from me rather than up my face across my eyes.

I had looked into a mask but 1) noticed that some of the suppliers used to carry several brands and carry none anymore--and one of those brands has an infomercial out there for them (the kind used to hawk products with suspect effectiveness or value), and 2) had some suspicions verified by talking to an opthamologist. They don't particularly like masks. Suggested I use some drops, which are thick and make the eyes fill like they have gel under the lids. Probably the same thing you were mentioning, Paula. Not really keen on those but I might give them a try anyway as they told me it helps some people with their dry eye issues. I have tried thicker drops during the day, but they drive me nuts--at night when my eyes are closed I can probably get used to them.

FWIW I have dry eyes after Lasik surgery--one of the common side effects of that surgery that a high % of people suffer from.

Thanks again for all the replies. When I am authorized i will add some to the review of the mask I started with that has the vent problem.

I think they hand everybody a full face mask, they tried to hand me one and I promptly told them I don't use that kind (I think they get them free from the distributors, so that's what they hand out) Explain your issue, and they may try to get you what you feel comfortable with (IF they have some in stock) and you can look at different web sites, or cpap stores and look at what is on the market, & ask what your insurance is willing to help you with, or if they have suggestions to help you (that's what they are there for) It takes time to find what works best for you, trial & error ....
I enjoy being with a group who like to share their "Hosehead" experiences, to remind me I am not alone.

I am assuming that your earlier FFM was a mask with a forehead anchor. Depending on facial geometry, those masks may leave some space at the top against the top of the nose and its hard to keep air from leaking and shooting in the eyes. I had the same issue with resmed Quattro air.

But the F10 has 2 top anchors that lie on the cheeks and it's fairly easy to tighten the top two a bit more than the bottom two. This ensures no leaking from the top of the mask.

Also, you can use mask liners cut from an old t shirt.
Started APAP 4-20, Closed range to 7.5-14, then straight 8.0 w/ Aflex 3
RDI always below 1. But sleep much much better at straight pressure.
Started on F10, Tried Quattro Air successfully. Finally settled on P10.

I use the F10 and leaks around the nose were an initial problem. I use two items to eliminate most leaks into my eyes. I tried Remzzz liners which worked ok but the Silent Night liners that last a week (same outlandish cost) worked far better. The liner in addition to a gel nose pad worked very well. I tried the Gecko gel nose pad but found one on Amazon for less money(< $9). Just started use so no history on it.

Contrary to PaulaO2's experience, I find the F10 works best if it rides higher on the nose than the maker recommends - different faces, different mask, different positions. Try different positions on the nose. Try different tensions on the upper straps - not too tight. I took several weeks to fine the best combination. Mark the straps so you can reset to same position and try to adjust the same on each side initially. I found if I put tension on the upper arm on the leaking side with my finger that the leak stopped - then adjust strap tension on that side slightly. All adjustment in moderation and do not make too many at once as you lose track of what reduced the leaks.

The Remzzz liner just sits on the mask and would bother my eyes, the Silent Night liners stick on the mask. Put them on the cushion portion then snap into the frame. I can control the excess material on the Silent Night to not bother my eyes, in fact, it seems to help direct air away from my eyes.

For me the gel pad is to protect the bridge of the nose. Even thought the upper straps are not tight I find that there is an irritation on the bridge of my nose - did not develop for several weeks usage - got worse with each use. It does seem to help to prevent leaks around the nose also. I tried band aid - Ok. Tried "moleskin" that works better but it is hard to remove. Gel pad worked best but harder to keep in place.

I also use a Ruby chin strap (Amazon) which I put on first (thanks to advice on this forum). It not only helps prevent dry mouth but holds the F10 straps in place when I shift postion. F10 straps do not pull the mask around when put on over the Ruby chin strap.

Wash the face well. I use a towelette from Costco that my wife uses to remove makeup. Some on the forum recommend baby wipes. Liners work best if you remove oil from the skin. Dry well.

Experiment with everything, liners, gel pad, strap tension, chin strap, etc. Give each new configuration time and see what works. My leaks are fairly steady at ~10 L/min 95%, even at my min pressure of 15 cm.
