Best Pressure Setting for Nasal Mask

I have nasal obstruction at night in one nostril, but I'm still trying to use a Nasal Mask. Can anyone recommend a good pressure setting for a nasal mask, when one nostril is obstructed?

Thank you.

You shouldn't need to alter the pressure even if one nostril is congested. The pressure in the airway can be maintained with just one working nostril.

Thank you. This might be a dumb question, but if your tongue is blocking your airway, does that make it harder to breathe through your nose without CPAP?

While it probably won't affect the ability to breathe through your nose itself the tongue can make is so the air coming in and going out the hose can't go anywhere. The blockage from the tongue will be further down below the nasal part of the airway and would then make it hard to breathe period. No matter if it was through the nose or the mouth.

So if the tongue drops backwards and downwards so that it occludes the airway either partially or fully it's going to affect the ability to move air no matter which way you are trying to move it...through the mouth or nose.

Thank you. I know that occurs on my back. Does that also occur while sleeping on our sides? Is a possible to have a such a large tongue that it blocks you airway while sleeping on your side?

I don't know about the side thing and I don't know about how much the size of the tongue could impact things.
Obviously the larger it is the more chance it has to flop around and be a problem but I have never really done any reading up on it.
I tend to read up on the stuff that affects me and that usually keeps me pretty busy. My tongue I suppose is probably average in size for my head but again I don't know that I have ever really seen any stats on what constitutes large vs small or normal. I would think that the size of the airway itself comes into play. Small airway and a large tongue would obviously be a recipe for problems.

I do know that for some people their OSA is significantly lessened when side sleeping for whatever reason or maybe they need less pressure to hold the airway open.
It wasn't the case for me though. My OSA was worse in REM sleep no matter what position I slept in. I did do a month long experiment once where I built a wall to make me stay on my side and my pressure needs were the same as when I didn't have the wall and would often end up on my back. Since I can't control REM and since position didn't seem to make any difference I didn't put much effort into studying any further the position thing because it really didn't matter. I had to deal with the REM thing anyway.

Thank you for your insights. I appreciate it.
