Ideal AHI
#1
Ideal AHI
After 4 months, I've plateaued at an AHI of 1.5.

I feel somewhat better, take fewer naps, and my eyes are not as heavy. Not perfect, but improved.

I did increase my pressures from 6-10 in Feb to 7-11 in March to try to get rid of the remaining events, but it didn't work. My ave pressure just increased by 1.0 without any further benefit to AHI.

When I look at my pressure chart, it still pushes at the upper limit of 11... 7-10 time a night, looking like it wants me to go higher. But I actually had a slightly lower AHI at the 6-10 than at the 7-11, so I don't know if it would be wise to increase the pressure again ( I get pressure induced CA's at higher pressures...I started at 5-15 and had a dozen centrals a night...I turned it down on the advice of a forum member, and the CA's diminished).

So, my question is should I just be happy and settle on the settings that give me the 1.5 AHI or allow my OCD personality to tinker and experiment to try to lower the average? 

Here is a typical night___

RE: Ideal AHI
Ideal would be 1.48 AHI. Too-funny   Once you get below 5 AHI it becomes a matter of how you feel. Do you wake up now feeling refreshed? If so than your at your ideal numbers.

Your Flow Limit looks a little elevated. Could you please provide a 2 minute section of the above data. . . somewhere around 23:00-23:02.

RE: Ideal AHI
I do feel much better...I used to get up with my eyes heavy and ready to go back to sleep. Now I am awake and alert (at least in the morning1). I take less naps...maybe a couple times a week versus 4 or 5 times a week...so yes, it seems to be working. I seem to be on a good trajectory.

Would you think I should go back down to 6-10? I do get more leakage at the higher pressure (but not above the threshold)...so it might be a bit more comfortable!?

BTW, my ODI has been about 7.5 for the last three months...very stable on average (but swings wildly occasionally). 73 minutes below 88% for the entire month of March. I don't know if this is good or bad, but I have been told this number should be below 5.0 also. It didn't change much when I increased the pressure.

RE: Ideal AHI
Have you used EPR in the past? If not you might want to try it at a setting of 1cm and see how you like it.

I'm a big proponent of at least trying a cervical collar if you haven't already, I found it really helps with OA and you may be able to reduce the pressure and hence, CA events.

I have...I think it was you that suggested I turn it off because of the centrals I was experiencing at the time. So I did. Do you think it advisable to turn it back on to 1?

I tried one at the beginning of my therapy, but didn't like it and sent it back to Amazon...it was too cumbersome...I may try a different model if you think it may help.

RE: Ideal AHI
You might want to try EPR of 1 and see how it goes. Some time has gone by and maybe you'll do OK as far as CA's. If not you can switch it back. Looking at your chart I don't see clusters of events happening so I don't think the cervical collar is needed.
