Can't reliably get below ~3 AHI

[Rcol]

Hello all. 

I posted a thread a while back about getting the right pressure. I started out with a big range of 5-12cm. I was getting up to 17 AHI (my diagnosis was 5.9 AHI). 

I followed advice - started wearing a partial cervical collar, turned flex completely off, and steadily bumped up my pressure. I saw noticeable returns until I got to around 15cm. I've spent the last month or so waffling around 15-17cm (fixed pressure). Occasionally, I'll get a fluke night with an AHI under 2. For the most part, I hover around 2.5-3.5. 

I see people on here with consisted sub-1 AHIs. When I look at my data and consider how I typically feel in the  morning and throughout the day, I wonder if my apnea is REM induced (or something), and that despite the improvement, I'm still missing out on restful sleep. 
  
The last two nights (attached) are pretty typical. Generally low AHI, but with events consistently spaced all throughout the night. 

Any suggestions? I think the highest I've gone is 17 - I got pretty bad aerophagia a couple of nights and wasn't seeing reliable improvement, so I haven't tried any higher.

One, make sure the changes you are making are not too close together. Let each change "settle" for at least a week before making another. Many keep a sleep journal where they mark down the change made (humidifier, pressure, etc) so they can refer to it later and/or input it into SH.

Two, as long as the AHI is below 5 AND you are feeling rested, all is well. You cannot compare your AHI to someone else because no two people are the same. Add in sleep patterns, life patterns, throat size, neck size, age, blah blah. I've had AHIs of over 4 yet fell rested. And I've been surprised to see AHIs less than 1 yet I felt like I hadn't slept well at all.

Three, to get better advice on the screenshots, arrange your SH graphs like suggested here:

Zoom in so we can see ~4 minutes. If it looks like OSA, then you need more pressure.

AHI<4? Don't worry about it. Anxiety over getting to -0- is counterproductive. Sometimes good enough is good enough.

Given the consideration that an AHI under 5 is counted as treated, therapy now should concentrate on "How do you feel?". If you wake up feeling better for using the CPAP therapy, then you should IMO consider the goal being met, that is also contingent on reasonably consistent results. If therapy is not making you feel better, then using Sleepyhead to post data the chart gurus can assist via suggestions of setting edits to help make it where you do begin to feel better.
