With CA events and UARS, it is counter productive to cycle to EPAP prematurely.  Think about it, it's a pretty easy piece of logic.  Thus Cycle is medium and Ti Min is extended from the default 0.3.

Makes sense. But why not Ti max longer too?

EPAP Min 7.6, PS 5.4, Ti Min 0.8, Ti Max 2.0, Trigger High, Cycle Medium. Standard length EERS, cervical collar, chin strap and mouth taped. Slept the whole night.

I'm obviously having positional issues. If I view the video footage where these clusters of events occurred, I'm always on my back. Vice versa for the areas with no/very minimal events, I'm always on my side.

For example
Rolled onto back 9:47:30
Events begin
Rolled onto side 10:42:00
Events end

Rolled onto back 11:19:00
Events begin
Rolled onto side 12:52:00
Events end

Rolled onto back 13:32:00
Events begin
Rolled onto side 14:30:00
Events end

Hi, Joey
_ very interesting.

_the way you are following looks promissing.

_It looks CA's are REM/Leak-dependent ones.

I know may be boring, however, would it be possible yoou post some 10min-duration windowns charts and scales, at the CA's strecthes, with the pattern I suggest you on post above, so that I am able to follow closely what could be happening?

all the best

Joey there are various means to prevent you lying on your back, which might help. Ideas I've seen (but never actually tried) include wearing a soft backpack, packing some pillows (or a wedge pillow) behind you, or (my favourite) sewing a tennis ball into the back of your pyjama top. You can also put a small cushion between your knees to keep your legs in a comfortable position. Choice of a pillow is important, as you need to keep your neck straight which can be difficult when lying on your side. I use a very soft duck down pillow which I can bunch up to support head and neck.

I've purchased a device to prevent me from rolling onto back, it should arrive by the end of the week.

I have a pillow with a cutout, so it doesn't push on my nasal mask causing leaks and I also have a body pillow which I always fall asleep with my arm over like these images. I've noticed (in the recordings) when I roll over to my right side, I don't stay there for long. Maybe because there's no body pillow on my right side?

RE: Interpreting sleep study results, EERS enhanced expiratory rebreathing space
Hi, pretty much there,

_ but enough to confirm my interpretation above, of REM/Leak-dependent CA's.

_therefore, what you have to tackle first would be the leaks. In turn, as I said you on posts above, your leaks, during REM, could be associated with loosing stripes (chin retreat)  while entering/during REM, positioning, etc. You would keep experiencing and decide what to do.

_meanwhile, based on your graphs of EAPmin x RR, and RR x PS, I think I could suggest you gradually increase your PS (0.2 every night) to 5.6, 5.8, and 6.0; keeping EPAPmin 7.6, and observe outcomes, first at FL max (good chances it would be bring to zero, as should be). I think you would be very, very close of your tailored parameters.

all the best

-Apologies, forgot to mention: not sure how the EERS could be interfering on your results, for the better or the good.
