Add to that the pressure pulsations and I definitely think that something is not working correctly. I would definitely have it checked out.
Hi PaytonA - I think the machine appears to be operating normally after the big arousal and likely change in sleep position around 23:30, immediately after which the Flow has improved strength and all snoring and Flow Limitations stop, so the Pressure starts slowly dropping.
Hi theone - I think you should immediately reduce EPR to 1 to see if you like it better with less EPR. Sometimes it takes us a while to get used to the pressure changes between inhale versus exhale, and perhaps it is causing you to momentarily interrupt your inhalation, making your inhalation somewhat stop-and-go?
If your machine feels like it is pulsating, I would guess you either simply don't like normal operation when EPR setting is 3 or else your inhalations are ragged, stop-and-go, maybe because you are bothered by (and reacting to) EPR.
I think it would help us see what is going on if you could post a zoomed-in period (showing about a five minute period) for a time when you think the pulsating may have been occurring while you were trying to get to sleep.
Obstructive Sleep Apnea is usually highly positional, with flat on our back usually being the worst position. If you can keep yourself from rolling onto your back while asleep this may greatly lower your pressure needs.
Hang in there. It will get much better.
