Need help desperately with Oscar Data

No worries B3, all good…

Thanks to Crimson Nape merging the threads, it makes more sense. All your numbers look good. As SleepRider and Gideon have said, your arousals look to be related to shifting body position. Hard to know for sure without zooming (3-4 min max) on the arousals (spikes), but it looks similar to mine.

If you are comfy with the current settings, not much to change there. You do have some small leaks that may be mask or mouth related, but they do not seem to line up with the arousals. Nothing extraordinary. They may be interfering with sleep quality, so something to keep an eye on. 

You have done a great job getting your apneas under control. Well done! Now to work on sleep quality. Give this article on Sleep Hygiene a read. Lots of good info. I would not change anything in your settings, other than possibly trying with response set to “soft” instead of “standard”. 

Keep at it. CPAP sleep can be a frustrating beastie. We have all at times wanted to fling the bloody thing out the window, but don’t give up. Consider getting a smart watch (I use an Apple Watch but there are many out there) to keep an eye on other factors that impact sleep quality.

A question for the experts: His/her medial Tidal Volume is about 300, medial Minute Ventilation is about 4.4, Resp. Rate is about 14.

Could it be that not enough oxygen is coming in due to this shallow breathing? Perhaps a night's sleep with an oxygen meter would shed more light on this?

Good observation edgnoj.  Oximetry monitoring during sleep may help show how effective therapy is right now.  But probably not completely necessary (can look back at sleep study to see SPO2 levels also).  

It would be good to bring this to the attention of your healthcare providers (Dr.'s and RT if you have one) about the 300 tidal volume and 4.4 or so minute ventilation. 

If my memory serves me correctly, BreakingBaddd has some difficulties with her nasal breathing (enlarged turbinetes, deviated septum, and faulty nasal valves.  Getting these worked on may raise tidal volume and minute ventilation significantly.  Just my opinion.

Would it be an idea to stent her airway open with more pressure? 
Turning EPR completely off (her Flow Limits 95% = 0,00, so no real need for that) 
Machine to AUTO, with minimal pressure of 9 and max 15 and see what the machine wants to do for her?
She needs to find something to keep her mouth shut during the night though. Or perhaps an F20 or F&P Brevida mask?

AHI and leak rates are well within acceptable bounds. No need for full face mask, and I think it would actually leak more and cause more disruption. More on respiration, the inspiration time is longer than expiration time. A zoomed image of 3-4 minutes duration would show the respiration wave and tell us a lot more than the statistics.

Here are a couple of shots with what I believe you are asking for!

So what exactly would I tell my provider? My sleep doc is so uninterested in helping me because my AHI is under control. I'm sure he'll brush it off but I can still bring it to his attention anyways.

Only the first graph was needed. What we see here is an OA event. To the point I was asking before regarding inspiration time, you have very good inspiration and expiration that are normal. Expiration returns quickly to near-zero flow with cardiogenic oscillation that are causing the machine to interpret the beginning of inspiration, but this is all normal. The only improvement to your graph I would suggest is to replace the pressure graph with the mask pressure. That would show if the machine is properly responding to the longer expiration time with the oscillations. The OA in your zoom shows an spontaneous arousal before the event, and there is a breath-hold that is counted as the OA. This is a false event and did not arise from obstruction. There is no flow limitation in these results. I don't see any reason to change settings, in fact lower pressure might be possible give the low event rate and the fact there is no obstruction evident in this screenshot.
