Yes, there's a learning curve. For some folks, it's a pretty steep learning curve. Others take to this crazy therapy a lot more easily.
Quote:My clinician told me to train myself to keep my tongue against the roof of my mouth. I trained all last night but sadly this necessitated my remaining awake.
I'd suggest doing the tongue training in the daytime. When you're awake and not talking, try to keep the tongue up against the roof of the mouth. When the tongue is up there, it effectively blocks the oral cavity off from the upper airway. So keeping your tongue up there will force you to breath through your nose.
If you have serious nasal congestion problems or other problems that prevent you from easily breathing through your nose during the daytime, the exercise of trying to keep the tongue on the roof of your mouth will be difficult. But if you are just a mouth breather by habit and you actually can breathe effectively through your nose, the exercise of keeping your tongue on the roof of you mouth will help train you to favor nasal breathing over mouth breathing.
Once you are routinely keeping your tongue on the roof of your mouth during the daytime, you may find that it stays there during most of the night.
It's also important to understand that with CPAP pressure, how easy it will be to keep the tongue on the roof of the mouth may depend a bit on the pressure setting itself as well as the ability of the tongue to resist relaxing and allowing itself to be pushed down off the roof of the mouth.
Also note: For some people when the tongue is properly placed on the roof of the mouth, it is possible to open the lips and have very little or no air blown through the mouth. It all depends on just how well your tongue can seal off the oral cavity from the upper airway.
Quote:Pardon me for whining but I'm still torn between loving my new nasal Wisp but spending the night with air blowing out of my mouth. Strangely, my numbers are good. Apparently the autoset increases the pressure to offset the air loss through the mouth? Maybe I should just let it blow?
What do the leak numbers look like? The machine can compensate for some loss of pressure through the mouth by increasing the air blown through the system. But once the unitentional leak becomes too large, the machine has trouble compensating. And once you're in large leak territory for an extended period of time, the reliability of the recorded data goes way down.
Your profile shows that you are using a Resmed S9. The Resmed only records the unintentional
leaks, and Resmed says that the Large Leak definition is anything over 24 L/min. As long as your leak rate remains below 24 L/min, the machine can compensate for the unintentional leaks. And then the question becomes: How much are the non-large leaks disturbing your sleep.
