Acid problems and pressure build up in mouth

[Hurdsy]

Hi everyone from a new user,

I've been using CPAP for a couple of months now due to chronic fatigue. I'm sure it's working but not to the positive extremes I hear some users reporting. 2 things I am noticing are, my acid reflux has returned (I have had this under control for 4 years prior to CPAP) and I sometimes wake with my mouth being filled with air. It almost feels like an inflatable being filled up, eventually the pressure builds upon and inevitably my mouth has to open to allow the air out. 

I'm using a Resmed Airsense 11 with the pressure set  5-10. I'm using P30i Nasal pillows most nights, occasionally I switch to a N30i Cushion if the pillows are causing discomfort but the fit is not as good. When i look at my readings on the machine in the morning there doesn't seem to be anything alarming. Most levels are very low.

Any advice on why the above is happening would be greatly appreciated, I've attached my sleep test results and can post my Oscar readings once I have my SD card reader which is on order.

Thank you in advance.

I'm sure someone will be along to address settings, etc., but have you thought of the age-old GERD hack of raising the head of your bed 6-8 inches? I had a doc finally persuade me to do this, and it helped! Turns out, I didn't have GERD, but I've left my bed like that, because evidently it was preferential (maybe for post nasal drip or something).

Thanks for that Halfasleep, the acid isn't much of an issue at nightime it's mainly in the daytime when i'm eating food. It just seems weird its only come back since i've started CPAP (I've read this can happen).

Not what you want to hear, but when I had the problem with air getting into my mouth and forcing its way out, my DME guy suggested using a FFM to equalize the pressure inside and outside of my mouth. It does help. It didn't entirely eliminate them for me, though. I have to use both a FFM and a soft cervical collar, which keeps my jaw from dropping down/back. I wish I could just use the pillows/cradle, but I just couldn't resolve the issue any other way.
