Tune UP my APAP, still waking up 2-3 times per night

[antilopa1981]

Hello everyone,
I’m new to all of this and looking for some guidance. I have been diagnosed with mild apnea (AHI: 29, supine 42.8, non-supine 11.1) with a T90 of 6% and a minimum SpO2 of 81%. My condition has been identified as moderate and positional.
I’m currently using a DreamStation 2 with a ResMed AIRfit mask (N20), which I switched to two days ago. I’m still waking up 2-3 times per night.
I’ve attached my OSCAR graphs from the last 2 nights for reference. My APAP is set to a minimum pressure of 6.5 and a maximum of 12, based on the 95th percentile and A-flex 3.
What adjustments or changes would you recommend to improve my sleep quality?
Thank you in advance for your help!

First, please read the link in my signature "Formatting OSCAR Charts". It explain what we like to see and how to format it.

Regarding your chart, you are still having some hypopnoea's, which tells me you are not using enough pressure. It looks like your Flex level is doing its job, so I would not suggest changing that as yet.

Give this a go...

Mode AutoCPAP
Min pressure 8
Max pressure 12
Flex level 2

One question is how did you end up with a flex level of 2?

Thanks for the reply. I will look into formating and post them again. i was playing with the flex 2 and 3 just to see if the hipoapneas can go lower. I was reading some people saying 3 might not keep the pressure.

reformatted charts attached. I will try the above recommendation

Fair play to ya. Could you repost without the calendar? That will show the bottom of the left hand table.

here we go, thanks

Cheers. Give my original suggestion a go and let's see how it works.

thanks a bunch. Will do

not sure if the graph is better, I woke up only once. Maybe I should keep these settings for a week or so.

It looks marginally better. Look at the top of the flow rate, it appears a bit smoother. 

Try increasing the min pressure to 9. I think you can leave the max pressure at 12.

What we are looking for is a less pressure swings and a smoother peak of the flow rate. 

One interesting anomaly is how the leaks increase during your H events. They are not in the large leak category, but still may be disturbing. Do you feel the leaks during the night and get awoken by them?
