I can, too, but I don't know another way to describe, online, how to make that seal to test it.

I really don't know how to describe it either, since it's all happening in the back of my throat, and I can't *feel* anything moving, but I can "think" it so air goes in and out my mouth, or my nose... or both.Janknitz wrote:I can, too, but I don't know another way to describe, online, how to make that seal to test it.

When I was a kid I loved to "swim" which mostly meant playing around in the water. We'd have "underwater tea parties" where we would pretend to drink tea and chat--making funny sounds under the water as we "talked". In order to do that, you have to be able to seal off the airway. But adults seem to forget how to do that, and the tongue positioning helps you feel what should be happening.
Do you have that backwards? In the beginning days, my wife would wake me up telling me that air was zooming out my mouth. I switched to a FFM, and the problem ended. My FFM has suited me well for many years.D.H. wrote: If it does, then the nasal path is open and it's possible to use a nose only mask. Conversely, if there's no flow out of the mouth and/or there is sinus pain from the pressure, then you probably do need a full-face mask.
Now if instead of trying to vocalize a K, you force the air into the nasal passage - sorta like a micro snore - you get what I call the Norman Fell snort. The late Norman Fell was the actor in "The Graduate" who played the paranoid rooming house manager Dustin Hoffman encountered when he went to Berkeley looking for Katharine Ross. Just by incorporating this nasal tick, Fell created an indelible character (IMHO). I related to it, because I did it too. Always have (which may account for my OSA today.) I can't find a clip of that scene, but here's my own version: https://www.dropbox.com/s/whkz8sxtudalf ... t.m4a?dl=0.

Yeah, so try my test. I can't move air in and out with my tongue in that position and the nose pinched off. It shows people exactly how that seal feels in the back of the throat. But some people cannot seal it off.palerider wrote:I really don't know how to describe it either, since it's all happening in the back of my throat, and I can't *feel* anything moving, but I can "think" it so air goes in and out my mouth, or my nose... or both.Janknitz wrote:I can, too, but I don't know another way to describe, online, how to make that seal to test it.

I like to say that it's using the same stuff that lets 'em blow up a balloon without pinching their nose shut... just in reverse it's just something one does.
I can still get some air around my tongue when doing that... it's trying to seal with the tongue, not the velum (soft palate) (thanks to Jay for link to pics of these things. viewtopic.php?f=1&t=113575&view=unread#p1096773Janknitz wrote:Yeah, so try my test.

In some cases, pressurized air flows through the velopharyngeal sphincter (i.e. between the lateral pharyngeal walls and the soft palate) into the oral cavity and then out through the lips, resulting in a mouth leak. When a mouth leak occurs, pressurized air does not reach the lungs and does not contribute to ventilation, thereby rendering the treatment less effective or ineffective. In addition, because of the one-way airflow through the nasal passages, mouth leaks tend to dry the mucosal surfaces resulting in nasal congestion after only several hours of use. In some applications, the CPAP system will apply a higher pressure through the nose mask when a mouth or mask leak is detected to compensate for the leak which only exacerbates the problem. In many cases, the side effects are often so severe that the patient is no longer able to tolerate treatment.
