Advice for dialing in pressures? - sleephead777 - 12-17-2024
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.php?title=Optimizing_therapy#Positional_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.
