Dry mouth - bt60 - 06-14-2020

I am using a ResMed 10.  Since starting on this my AHI is usually below 1 which is great. Now the problem.   I always wak up with a dry mouth.  I assume that this is from mouth breathing but when I go to bed, my mouth is closed and I breathe through the nasal pillows. I assume that during the course of thehe night my mouth slacks open and thiat is the beginning of the dry mouth.  I have seen these chin straps with them.  Does anyone have any guidance on this topic.
 Also, I usually get my reseed score for leaks at about  13/20.  Any suggestions there would help too.  Thank you.

My understanding is that dry mouth tends to indicate mouth leaks or breathing. A newer chin strap that a few here on AB have tried and liked is Supplier #37 Knightsbridge. They have a dual band setup that pulls the jaw straight up and not backwards. You have a sort of cap that is worn with these straps are connected to it. I'm considering it myself sometime after the new machine issue is resolved, because I'd like to try other masks than just full face ones if I can be successful at it.

from the Mask Primer See my signature

Mouth Breathing is when you open your mouth and the air pressure from your PAP is venting out your mouth typically showing on your charts as a large leak which can substantially negate the effectiveness of your therapy. It is generally not good. The solution varies depending on the person
With OSCAR look at your Leak Rate graph where it is shaded (large leak/ LL), flat tops on this graph suggest mouth breathing. In OSCAR right click on the left header of the Leak Rate graph and click on Dotted Lines then select "Leak Rate Upper Threshold" to get a line across the graph for ResMed. Manually set the value for Philips Respironics. Severity depends on how much over this threshold and for how long it is in the Large Leak territory.
How to manage Mouth Breathing, not in any particular order.
Tongue Trick. Place the tongue on the roof of the mouth, Practice during the daytime. The idea is to train the tongue that this is a good place to be, does not happen overnight, but it works for some. The tongue trick is where you want to be but it takes a lot of time and some people just cannot get it. Place the tongue on the roof of your mouth and breathe with your mouth shut. Breathing thru your nose, right? Now leaving the tongue where it is open your mouth, you should still be breathing thru your nose. Now that you have that down move your tongue, breathing thru your mouth right? OK, put your mask on, under pressure, and repeat the above. Expect to need to turn your machine off when you start to repeat. Add talking while under pressure, It takes a while to get any of this down. It took me months. The exercises above are to help you understand the positions that cause the issue and how to correct it. For all this to become automatic will take a while.
Cervical Collar. A "soft" Cervical Collar (Releaf is popular). This helps support and align the neck and keeps the jaw/mouth from dropping. This is becoming a very popular option. Rarely used prior to mid 2016. Users are posting a high success rate with this device. When OA tends to occur in clusters at different times of night. It's an indication that an obstruction may have occurred when the chin tucks towards the chest. It's common, and the solution is either an ergonomic pillow or soft cervical collar that prevents the neck and head from being out of alignment and cutting off the airway, but they can be comfortable, prevent leaks and prevent an airway from closing up due to tucking your chin to chest and other issues. An Anti-Snoring collar or Sleep Collar, which has a small strap in back also works. (Dr. Dakota is popular)
It's a very small investment that has worked very well for some people. More pressure may solve the obstruction, or it might go away with positional therapy.
Chin Strap. A chin strap is to manage mouth leaks from a variety of causes. Most result from the jaw-dropping or opening either partially or wider. The chin strap is to gently keep the jaw closed. If you have to crank it shut to make it work this is not the correct solution. Note that your jaw is strong enough to open if it wants to. There is one chinstrap that is notably different than others, Knightsbridge Dual Chin Strap which pulls up instead of back. Search for it if you desire.
Ergonomic Pillow or CPAP Pillow, The purpose is to maintain a proper head and neck alignment while allowing for the mask maintaining the seal in multiple positions.
Mouth Guard The concept here is a closed mouth guard to keep the air from leaking out.
Taping. Definitely the most controversial. The purpose of taping is to seal the lips and prevent mouth leaks/mouth breathing. It is not to stop the mouth from opening. I make sure that I can easily open my mouth when taped, if I need to.
FFM – Full Face Mask or Hybrid Mask. This is a very traditional solution and it is generally effective.
Dry mouth is a symptom mouth breathing that is uncomfortable. It can and does occur with some users of a Full Face Mask.

  • Many users use a product called Biotene to get relief from this symptom.
