Aknakon, I'm hoping a moderator will move this to a new thread since it is not relevant to the original poster, and you should get individual help.

those statistics are a one-night summary and what appears to be a 7-day average of your treatment statistics. What stands out is you are having about 30 apnea events each night over 6-hours of use, resulting in an AHI of about 5. Those events are mostly obstructive and hypopnea, which suggests you need more pressure to keep your airway from closing. You are using EPR (exhale pressure relief) of 3, so your CPAP pressure of 11.0 is reduced to 8.0 during exhalation. I suspect that this is when your obstructive events start.

You have a couple options to reduce the obstructive apnea. Either reduce EPR to 1 or 2, or increase your pressure by 1 or 2. Either option will avoid having EPAP pressure lower than your therapeutic needs.

Do you have a S9 Autoset or Elite? You may want to download the free SleepyHead program to get a better understanding of your therapy and data.

Thanks for the help and My apologies fro being in the wrong thread.

I have the sleepyhead software as a matter of fact those statistics are taken from that software.

I have the "elite" which I think stands for "better than most but not really elite".

I will be getting a NEW machine in the next month or so. Im thinking S10 Autoset OR S9 Autoset.

I will make the adjustments now. Thx for the help.

Aknakon, welcome to the forum. A moderator moved your post to a separate thread, so no harm, no foul. I think you will find auto CPAP (Autoset) to be both comfortable and effective for you. My suggestions were based on fixed CPAP. Once you have auto-cpap, a pressure range can be used, and that can automatically take care of the changing pressure need through the night. Based on Sleepyhead, are your events spaced evenly through the night or clustered?

BTW, once you have 4 posts in, you can post the charts on the forum by attaching them, or using off-site image hosting as described here. https://sleep.tnet.com/reference/tips/imgur

Here is a link to The Beginner's Guide to SleepyHead. It should help in understanding your data.

Additionally, there is a youtube video that may help. I suggest that you google the phrase, "interpret your sleepyhead report data".

Good luck!
