Looking at this slide: https://i.imgur.com/Fi8g0fK.png It shows that UARS flow has a longer exhale. But I always had more difficulty inhaling than exhaling. Here's my flow rate: https://i.imgur.com/Dj7ZuaS.png It looks more like a triangle than the normal breathing from the slide. Having little expe...

Thank you all for your help! I do change sleep position every 10 to 20 minutes. So the arousal being the cause of the change in breathing patterns makes sense. I suspect upper airway resistance (from my nose/sinus cavities). But the CPAP has not been very effective. Maybe surgery will help.

Here's another example:

It's happening every 10 to 20 minutes. They are mostly flagged as Clear Airway Apnea events.

Is that Cheyne–Stokes respiration?
I seem to be suffering mainly from that type of breathing. My breathing goes from normal to intense and then it stops.

I'm surprised people still suggest the big sport mouth guard when it comes to teeth grinding at night.

Thank you, that's great advice.

Thank you all for your answers. I went ahead and installed SleepyHead. My clinical sleep study was negative for sleep apnea, but I had so much trouble falling asleep with all the gear on me that I don't think it was representative of a normal night for me. So my doctor gave me the prescription for a...

Good day ladies and gentlemen! I'm new here and to cpap in general. I'm sure I can learn a lot from your wisdom and experiences. So I decided to start a journal describing my attend at a better sleep (and better health). Apparently I may suffer from Upper airway resistance syndrome, but I'm not sure...

The OTC "one size fit all" night guard may seems like a good solution, but it isn't for most people. For the night guard to protect your teeth and gum without causing additional problems, it needs to be thin and cover all your teeth. And that is usually not the case for boil and bite night guard.
