Understanding My Oscar Data - Improving Usage, Possible CSR

[brokenslinky]

After two sleep studies, I was diagnosed with central sleep apnea and atrial fibrillation.  I was consistently having 100 to 139 events an hour during both studies.  I've been using a BiPAP machine now for just over 3 months now.  Started out with a nasal pillow mask and switched to nasal mask.  I have a full beard and wasn't ready to shave it.  Also felt like the nasal pillow was blasting the air into my nose.  Definitely feeling the positive effects/benefits of using the machine.  I'm typically under 10 events an hour with infrequent nights less than 20.  My AFib is also gone with the help of an anti-arrhythmic drug.  
That said, I'm wanting to ensure that I'm getting the most out of setup that I can.  That led me down the rabbit hole of installing the myAir app then ResScan then OSCAR.  I'm consistently getting a score of 90 plus on myAir.  When I looked at the data with ResScan, I was seeing very consistently timed events. That led me to download OSCAR.  Looking at the flow rate on OSCAR, each of the events was at the beginning of what looks like a Cheyne-Stokes breathing pattern.  Reading a bunch of posts here, I see that it can be machine induced events rather than CSR.  Although, my family on both sides have a history of heart attacks, strokes and other heart related nasties.  I also read that it could be position induced.  A few weeks back, I bought one of those sleep apnea pillows to help reduce the leaks and the possible CSR.  It seems to be helping some but still seeing the CSR type breathing patterns.  
I started with a ResMed AirCurve 10 VAuto and now I have an 11 VAuto.  Both are set to BiLevel-S mode.  I was originally at 15.0 and 20.0.  That was dropped to 13.0 and 18.0 to see if it helped with the air flow from the pillow mask.  
Do I start with dropping the values incrementally or try a different mask or sleep hanging upside down from the ceiling like a bat?  Wouldn't CSR be detected during the sleep studies?
Attached are some random screenshots of my data.

I'm not the best at the CSR charts, for most these would be periodic or variable breathing. However your AFib might be contributing to these.

Two things I do know, PS 5 is very likely adding to your CA, and you cannot treat diagnosed CA with VAuto. You need the ResMed ASV to actually treat them.

You are still having a lot of leaks as well.  Here are some tips to help decrease those leaks (fixing the leaks may decrease the CSR): 


[*]Mask leak solutions                                                                                                                                                                     Mask Primer                                                                                                                                                                                                                                                                                                                                                                          Your CSR do look like the real CSR, but there is no definitive way for us to say for sure one way or the other (I am not a Dr. and don't give medical advice).  Presenting these OSCAR charts to your Dr.'s would be the next step. 
 
Here is some reading from our wiki on CSR also:

Thanks for the feedback SarcasticDave94 and Jay51.  I had read those mask leak and CSR links.  So I'm thinking I'm pointing myself in the right direction.  Also found the videos from CPAPReview and TheLankyLefty27 on Youtube.  Contacting my Dr was next on my list.  I didn't want to get the usual eyeroll and "Dr. Google" response from my Dr. if the data I was presenting to him was from items that were "easily" fixable my me.

I had excellent results using VAUTO mode and setting the trigger to extra high.  It helped my 
CA a lot.  However, I agree with dave that as many as you had may need a different machine.  I would give the trigger setting and VAUTO a try and see if it helps...
