Please help me to improve my CPAP therapy

[Eugene1]

I started using BIPAP therapy in March 2019. I noticed in the last six months or so, my AHI has increased from 3ish to 5ish. I do not know what the reason is. I also have more snores than before. I am attaching my OSCAR screenshot here.  Could you please advise on how to improve it? thank you.

See the clumps of Obstructives on your graph... this is Positional Apnea.
This usually occurs if you're sleeping in a position that would cause "chin tucking".

Be sure your pillow is not too tall or that you're not sleeping on more than one pillow.  This can cause your head to tilt forward and cut off your air.  A firmer but flatter pillow may help.  If not, you can try a soft cervical collar to help keep your head/neck aligned.

I'm also seeing some low level leaking (not high enough to affect therapy), but if happening all night, can be an annoyance.  Your mask cushion may need replaced.  

You've been at this for awhile, so I'm wondering if you've changed anything like pressure settings.

Thank you so much for the advice. Last night, I used a new mask cushion, and my AHI was reduced to 4.9. I will upload the OSCAR image later. I will also try to use a soft cervical collar. I use SCC whenever I take an app during the day or on a long-haul flight to nap. I know I can not lie down, and the SCC improves my sleep without a CPAP machine. Thank you.

When flying, try a travel neck pillow turned around so that the opening is in the back.

Thank you for the suggestion. Next time will try out a travel pillow. Amazon seems to have one. Here is last night's sleep. It improved with a new F20 mask cushion. Tonight will try out with an SCC. Thank you.

Yes, that's a big improvement. Let us know how the collar works.

It is amazing with the cervical collar; last night's sleep improved to AHI 1.43. I used this one from Amazon.

I am happy that it finally reached the AHI level when I started my CPAP journey in early 2019. Thanks so much for your help.

That looks pretty good. Keep a watch on the Obstructives.

I like the style of the collar. It's not too bulky and is open in the back.

Thank you for your input.
