sleepy head data

I am going to try to post my data. Can someone help me understand it please?

Thanks

I have a link to a Glossary of terms in my signature line. Read it and then come back with anything that needs clarification.

We generally like to see AHI less than 5...yours isn't there yet and it appears that you have the machine set to maximum of 10 and minimum of 5....the bulk of your AHI is obstructive in nature.
You are pretty much maxing out the pressure all night long. This points to the machine wanting to go higher and it can't. It wants to kill those obstructive events and can't.
How did you come up with the 5 to 10 range? The minimum may not be optimal and the maximum sure isn't.
Leaks don't appear to be an issue. Your line in the sand is 24 L/min. That large max leak is likely when you took the mask off or repositioned it. From the other numbers it appears not much leak....now if you are seeing 0.0 each and every night in those first 3 columns..might want to unplug the machine from electric source and wait a couple of minutes then plug it back in. A few people have had the machine get stuck reporting zeros....rebooting the machine usually fixes it. While we can and do get 0.0 leak numbers...it would be uncommon to get them in all 3 columns each and every night...so do the unplug thing just in case. We wouldn't want a large leak to be inadvertently hidden because it might be the leak that is the problem.

So go read the glossary and if you will ask specific questions about items you aren't clear on we can offer more definite responses.
I also have a sort of tutorial thread going...link in my signature line. Read it and it may also answer some of your questions. It isn't polished but there is useful information in it.

With an AHI of that level your pressures likely need to be increased. Also your leak rate is high maxing over 100 that may be affecting your AHI as well. Have you tried adjusting your mask?

The rate was set by my DME. The Dr, on basis of my titration test came up with a 7 pressure reading so he wanted to try a 5-10 range on the APAP. So from reading your glossary, the 95% number is the 95% of the time the rate was at 10 or lower. I am not sure I understand why you wouldn't want it to be near the max number. Is it based on the occurence of apneas that are continuing now?
I have only been on CPAP for 4 days. Looking at the stats page from all the days, my average pressure is 8.38, 95% is 9.8. AHI average is 10.7. Leaks are .48
Thanks for all your help.

Yes, it is because of the current AHI showing. If you were below 5 AHI...wouldn't matter so much that you were maxing out your maximum because a less than 5 AHI would be acceptable.
Since you are double that amount then it points to the pressures not being set optimally.
I suspect that the minimum of 5 is not sufficient when you add the EPR of 3 cm reduction into the mix.

It would be helpful to see the overall graphs and not just this summary section. So that we can see the events in relation to the pressures...like are they occurring a times that the pressure is lower (as in near the minimum) or are they occurring when you are maxed out also.

When they did your titration they didn't factor in a 3 cm drop during exhale when they came up with your 7 cm suggested pressure. You would be surprised how much a little 1 or 2 cm pressure difference will make.
Sometimes the minimum has to be adjusted upwards a bit to make up for the EPR reduction....so not only are you starting out less than 7 cm...when you do get to 7 cm on inhale you are still only using 4 cm on exhale...likely allowing some events to sneak past the defenses.
