Advice for dialing in pressures?
Hi All,
I've been using CPAP for a few years now but am at the point where I really want to dial treatment in and see if i can lower AHI. I've attached a overview in Oscar which should help show previous treatment data. As of last week I've started to raise min pressure and lower max to find a better range. Thoughts on any way I can improve settings? It seems to be raising my AHI from around 3 to 4-5 instead of lowering it. Please let me know if I need to provide more data for you. Thanks in advance!
There are a couple issues. You have a moderately high residual AHI with periodic clustered OA events. The fact they occur close together suggests we are looking a positional apnea https://www.apneaboard.com/wiki/index.ph...onal_Apnea This can often be resolved by changing pillows or avoiding sleeping positions that lead to chin tucking. Secondly, you have flow limitations (95% between 0.06 and 0.11) that are likely causing respiratory event related arousals. We can resolve that by using a higher EPR setting of 3. Read the positional apnea wiki and share any thoughts on how this may apply. Try increasing minimum pressure to 8.0 with EPR full-time at 3 and keep maximum pressure at 14 for now. This will result in a pressure range of 8/5 to 14/11 compared to current range of 6/5 to 14/13. I think you will find this more comfortable, and if you can resolve the positional issue, we should see an improvement in AHI and sleep quality.

Hey Sleeprider, Thank you so much!!!! I made the suggested changes and have seen a pretty massive improvement in AHI, screenshots below. I also got a new pillow the same day as making the changes so I think a bit of both have helped. How are things looking now, any room to fine tune additional settings? Thanks in advance!
Well 777, well done! That's a lot of progress. Still some positional obstruction, but much much better. I'd like to see you try +1 cm of minimum pressure to see if we can clean it up a bit more.

Will do and report back in a week or so. Thank you again!

Hi, have some updates over the last week. Since making the change from 8-9cm it seems as if my CA and OA have been trending up in the wrong direction. Should we move it back down to 8cm? I've attached the most recent night of data which was by the worst AHI. Thanks!

Fdxmike, I'm getting really confused here with your questions in Sleephead777's thread. I'd like to split your posts into a separate thread to discuss your therapy. I have split your posts to your own therapy thread here. Please keep all questions related to your therapy in that thread, and we will focus on Sleephead777 in this thread. https://www.apneaboard.com/forums/Thread...-pressures
Sleephead777, your results on January 2 were considerably better with lower pressure of 8.0-14.0 EPR 3. What else has changed other than pressure on 1/15 of 9.0-14.0 EPR 3?
