More Adjustment Needed?

Post by Jkb1234 » Thu Jun 21, 2018 6:10 am

Well, 3 nights on 10.5 pressure, the last two were both around 1.78. My "target" is a little lower.

I feel good though (headaches are gone and I'm more alert when I wake), but when I was compliant before the most recent usage (3 years ago) my numbers were below 1.0. I was using a different mask at the time, I was 20# lighter, and my pressure was 7.0 fixed..

Let me share a little story of mine since you are just 3 nights into this trial.

A while back I had a chance to try a different type of machine and I had to do like you in that I had to find an optimal pressure.
After 3 or 4 nights I decided on a pressure setting that gave me decent results but maybe not quite as low of an AHI as I really wanted...I was seeing AHI between 2 and 3. I gave it 6 weeks at those settings and slowly I saw the AHI started to creep downward. At the end of the 6 weeks my AHI was fairly consistently running between 1.0 and 1.5 with a few nights below 1.0...that's with no changes over a 6 week period. There is some truth to the give it time thing.

And I know we all want to satisfy the curiosity itch of "what would it take to get the AHI even lower" so I did another experiment where I increased the pressure over 6 weeks..1 week at each setting to give it a chance to establish trends and patterns and eliminate any fluke nights. So over 6 weeks I increased the pressure 3 cm...from a minimum of 10 to minimum of 13. The AHI was the same at 13 as it was at 10 cm minimum. Sleep wasn't any different either and neither was how I felt. There can come a point when more pressure doesn't eliminate the apnea events...I think probably because the flagged events are more likely SWJ events and not much we can do about those.

Remember you can't do anything about the open airway (CAs/centrals) apnea events....they may or may not be real and either way you can't do anything about them and need to mentally remove them from the evaluation process. They aren't a huge part of you AHI but they are a part that you really have no control over.

This is generally considered good. This number means that you're having an every 33 minutes (on average).

If you can get it lower, that would be better. However, if you can't, you should not obsess over it.

Thanks for the input, it probably is a good idea to try this setting for awhile. I'm already having better results at 10.5 than i did from 7.0 to 9.5. The only thing is my brain fog that has developed over the last 3 years (I often have words end up on the tip of my tongue), so I do want to make sure I'm not adding to it if at all possible.

Personally, I try to wait a minimum of two weeks between changes. I prefer to make changes based on trends, not single night results.
