Considering all the problems with this mask - careful adjustment required, nose clips required, daily cleaning of "oral appliance", and cheeks puffing out - have you considered the RespCare (Innomed) Hybrid mask https://www.cpap.com/productpage/RespCa ... -Mask.html?

The Hybrid covers the mouth and has nasal pillows for the nose. Your field of vision is unobstructed so you can read or watch TV while wearing it. The nasal pillows would seem to be less "claustrophobic" than your nose clips. Cheeks puffing out is not a problem with the Hybrid. You might also be able to do some nosebreathing with the Hybrid and nosebreathing is healthier than mouthbreathing.

Here are some lessons I learned on the use of this oral only mask made by Fisher-Paykel.

01) The mask needs to be adjusted carefully to avoid being too tight and making your lips feel lousy in the morning. There is a small adjuster ring that allows you to adjust the distance between the inner mask (the part in your mouth) and the outer mask (the part that presses on your face.) The pressure between the two has nothing to do with leaks but everything to do with comfort. The inner piece called the Snap Flap I think, seals against leaks by being pushed by air pressure against the inside of the lips. The outer flap keeps the mask positioned and correctly aligned. Try to make the adjusted distance just close enough to provide a snug fit and not so close that you lips are overly compressed. If you wake up in the morning and there are compression marks on your face, you have the ring adjusted much to close.

02) The mask is an oral mask only – there is no involvement with your nose. F-P supplies some nose plugs so that you don’t blow air out of your nose at night. They indicate that over time, you can learn not to use them. Just recently, this started working for me. I experimented with all three sizes of plugs and nothing was comfortable and worked well. My nose was sore in the morning. So … I tried swimmers nose clips and acoustic ear plugs and some other stuff without success. In desperation, I dropped by my doc’s office and asked if I could have a couple of the nose clips he uses when testing for lung capacity. They worked like a charm and I have been using them ever since.

It has been reported that some people experience some irritation with the pads on this nose clip. I never did but my suggestion to cope with this problem is to carefully clean the foam pads to remove any accumulation of debris and skin oils. Cleansing your nose and mouth area before bed time will likely also help.

The arms of the nose clip may lose their spring after a long period of use. In this case, slip a rubber band around the arms tight enough to bring the foam pieces together. Leave it this way during the day and remove the rubber band at night. Adding a rubber band and using it that way is really too much pressure.
If the clip is too tight, then place a small block between the foam pads during the day (perhaps a half inch thick) to cause the arms to relax just a little. Adjustments like these provide for increased comfort.

After some period of use, the foam pad gets loose and can come off at night. I just put a drop of Gorilla Glue on the post where the pad fits and replaced the pad. Now they never come loose. When asked for a sample to see how they work, I already have applied the glue before sending them out.

03) This mask in an oral appliance. It’s in your mouth for several hours each day. That means wash it every day when you get up. Just like brushing your teeth in the morning. Facial masks can go a while between cleaning – not this mask --- every day!

Use a mild soap and rinse thoroughly!! I currently use just running hot water and rub until the mask squeaks.

The inner flap just pulls off of the outer flap and mouthpiece. The swivel diffuser snaps out of the outer flap assembly. Do not remove the adjuster ring, it’s a real PITA to get back on and adjusted correctly. Only wash the inner flap and the outer mouthpiece assembly. If you wash the swivel diffuser, you should remove the diffusing filter and replace it after all is done. I have recently looked at the recommendations of F-P on cleaning the Oracle 2 mask. They recommend mild soap and water and a moderate temperature not to exceed 10 minutes immersion. In addition, they recommend sterilizing the mask using an antiseptic mouth wash diluted about 15 to 1 with warm water. Again, not to exceed 10 minutes immersion. The individual parts should be left to dry and only assembled when they are completely dry - about 1 to 2 hours later depending on your humidity. If you don't get the parts actually dry, the little water that remains between the inner flap and the hard plastic mouth piece won't dry by itself. This will result in tiny bubbles when you use the mask. My Respironics machines recognizes those bubble sounds and categorizes them as vibratory snoring.

When re-installing the inner flap, be careful to make sure that the little ears are correctly seated within the inner flap. If they are not fully seated, some leaking will occur.

I find that sometimes the "ears" on the hard mouthpiece that slip into the inner flap, don't always get in just right. If you hold the ends of the inner flap and pull them directly apart, the "ears" will snap into place.

04) F-P supplies a head piece (a strap) that goes from the mask around your neck to hold everything in place. They call it optional and I didn’t use it at all. However, if your pressure is higher than mine (IPAP max 19 EPAP min 15.5) then you may need to use the strap. My machine went nuts a couple of times and ramped the pressure above 20 and the mask leaked like a sieve and blew off once, literally. Philips-Respironics replaced the machine after this happened again.

The strap will prevent that problem. The second problem you might have is your cheeks puffing out. That’s a bummer and feels strange. The strap goes directly from the edge of the outer flap, across the cheek at about the tooth line and presses in so that won’t happen.

in getting ready for my ASV machine, Respironics 960 AutoSV Advanced, I started using the strap loosely and started using a very soft cervical collar. These two things stopped all major leaks.

05) Cleaning the area of the face on which the outer flap rests helps a great deal with controlling leaking.

06) Last but not least, this mask is a miracle for me because I have severe claustrophobia and can’t wear any of the full face or nasal masks.

07) On the issue of dry mouth:

Oral masks of any type are blowing air into the throat and not through the nasal passages. The body is designed to take air in through the nose and not through the mouth. The nose has special structures that help increase the humidity of the air we breathe and to not themselves dry out. Unfortunately, the mouth doesn't. So it takes extra effort to make sure the air coming in through the mouth is wet enough to combat this problem.

In addition, because of the very high humidity level you will be using, rainout in your hose and mask may be a problem. I added a wrap for my hose that provides extra insulation so the water doesn't precipitate out before it gets to me. You can get one online or at your DME for about $15 USD. This won't be a problem with the new 60 series heated hoses.

Set your humidifier setting to the highest it will go. If that doesn't solve the problem completely, get an evaporative humidifier from Walmart, etc. and have that going on all night. Don't get the heated one, they use too much electricity nor get one of the "Cool Mist" ones because they spray water into the air together with the minerals that are in the water. When the water evaporates, the minerals precipitate into a fine white powder that gets everywhere and into the filters of your CPAP machine. Because this powder is so fine, I suspect it gets through the original gray machine filter and directly into your lungs. I think the ultrafine filters will stop it but why take a chance.

I ahve started using a second heated humidifier (F-P HC 150) and a Hybernight heated hose to supply enough humidity to last the whole night.

08) Filters - I use the gray filter that comes with the machine, the ultrafine filter that now comes with it, and a bacterial filter that fits between the CPAP hose and the short hose on the mask. These three block most everything. I change them once a month. For a while, you should check each week as the dust and pollen situation in your house may be different from in mine. As the car salesman once said, "Mileage may vary."

09) Chin Straps: the manufacturer of this mask advises not to use a chin strap with this mask. A chin strap puts pressure on the jaw and pushes it backwards. This movement, even though very small, increases the occurrence of obstructive events and then requires higher pressures to correct. The solution to leaks in the middle of the night with this mask caused by jaw drop as you get fully relaxed is the use of a soft cervical collar. A cervical collar provides support for the jaw without putting any pressure to move it in any direction. Since using a soft cervical collar, my unintentional leak rate has hovered around zero.

Wow this post is so relevant to me, I have only been using a PAP machine for less than a year and have found it diffcult to get a mask to suit. Nasel and full face masks leak and when I add a chin strap I feel like my head is all wrapped up and it is uncomfortable. I tried nassel pillows but even with a chin strap there were still leaks through my mouth.

I have only been using the oral mask for a couple of week now but find it a vast improvement, especially the lack of straps. My major problem is leaking through the nose. I have tried the bungs that came with the mask but find them uncomfortable. I have tried swimming nose clips but they are not designed for prolonged use so pinch after a little while. I have tried to train myself not to breath hrough my nose while using the oral mask but it causes my throat and mouth to dry out too much and wakes me up. I may just need to perservere with this one.

I like the nasel pillows as part of the hybrid mask but not likeing having to go back to full head stratps, although there will be no chin strap. Is there an oral mask with the snap fast seal, single strap around neck and nassels pillows? Probably not as I van not find one online and think someone would have posteded it here.

I love the mask still in the break-in stage at 1 week - only issue is the nose "reverse leakage" meaning I have air coming OUT of my nose. I tried Speedo nose plugs and I actually had an allergic reaction and got a staff infection on my nose so I am afraid to try your external option. I am going to try taking an extra set of nose pillows from my Hybrid mask and stuffing it with something to see if they work.

Older speedo noise plugs may contain latex; look for silicone; and clean the nose very well.

These oral mask must be tough. I tried to stick a Swift FX tube in my mouth to see if I could tolerate an oral mask but I blew up like a balloon

I just stopped using the Oracle because of the nose plug issue. I had been using it for over a year successfully. Those plugs were causing an non healing sore on one side. My nostrils are different sizes and I had rigged up a large and medium combo. Still had pain, plus I had to tape them in place!!!! Those plugs you show look great! Thanks. I made a copy of your first post

I am now using one that would really mess you up.. the Hans Rudolph! Who knows, I may be switching back or do the alternating thing.

The supplied plugs that come with the Oracle mask are awful. I'm really surprised that you lasted for a year.

The clips that I used to use cause no nose irritation or discomfort.
I'll be glad to send you a couple from my stash as I no longer need to clip my nose. I somehow learned not to breathe through my nose at night.

Check your PM inbox.

Cheers,

For any one interested, who uses the Oracle. I created a 'liner' like those for nasal masks for my Oracle.

• *Take your oldest, softest t-shirt that you no longer wear, but do not want to throw away.
  
  *Using the inner section of the Oracle as a template, cut out a shape that is roughly 1/2 inch bigger all around.
  
  *Fold in half.
  
  *Make a half-inch cut with scissors in the middle...
  
  *Then once you have that cut... make two half inch cuts along the fold on both side.

This opening will go over the inner section. When putting the mask on, hold the material against the outer section. Once you have the mask in place, you can pull a little here and there to even the material out.

What a wonderful idea. My wife sacrificed an old pair of flannel pj's to the cause and I made my first one.
Will try it out tonight.

Since I don't use the strap with my mask, it looks as if the hole in the outer flap for the strap clips could be used as a means of anchoring the fabric so it doesn't move in the night. A small slit and the clip could go through and onto the mask to hold the fabric in place. That's an experiment for tomorrow.

Thanks again for the wonderful idea.

When I tried to use the Oracle mask, here's how I managed to use it without the nose plugs.

The idea is to close off the back of your nose with your soft palate. This is the same thing you do when blowing up a balloon. You can blow up a balloon without pinching your nostrils shut.

What I would do is put on the mask, start the machine, and then make like I'm trying to blow up a balloon by blowing into the mouthpiece. Then when I feel my nose seal off, I'd sort of freeze up and consciously relax slowly. The pressure in my mouth would seem to hold the seal on the back of my nose.

I was able to maintain this seal and drift off to sleep.

If you can do this, you have the advantage that there's no pressure in your nose, your sinuses, your ears, or the the nasolacrimal duct leading to your eyes.

I still found the mask too uncomfortable in terms of dry mouth and throat, and found that not breathing through the nose bothered me.

I need to try my again as I really liked it, but had trouble actually sleeping while using it.

As one who does not normally breathe through my nose while lying down, I had no problem without the plugs. It felt very natural for me. The only problem I had is that it forces me to keep my mouth open more than i normally do. Usually, my teeth are only barely open, enough to allow enough air through. So, being forced to have the mouth piece between my teeth causes my jaw to be open wider and tense. I haven't figured out how to get past that. Otherwise, I would love this mask. I keep telling myself I will try it again on nights when I don't have to get up for work. But I keep forgetting.

Even though I can't tolerate nasal pillow/nasal masks due to clogged sinuses, I still mostly breath through my nose when using a full face mask. As a result, i would never be able to tolerate the oral mask. But I admire anyone who has made it work for them.
