You might take a look at your sleep study results and see what position you were sleeping in during the time at 10 cm pressure and also if you had any REM sleep during that time.
Obstructive apnea is worse for almost everyone when they're sleeping on their back compared to on their side or stomach. Lots of people also have more severe apnea during REM sleep. If you have a copy of the results from your first sleep study without CPAP, you can see how your obstructive events varied with sleep position and with REM vs. non-REM sleep.
In fact, unless you just want to have another titration study in a lab, you can take an auto-adjusting CPAP machine and do your own titration at home.
I'm not saying that you should do that if you prefer to have an in-lab titration.
P.S. I just read in your latest post where you wrote that you have an auto-adjusting machine. Ignore what I said above about scrutinizing your sleep studies, unless you just want to do that to learn more about the subject.

The conclusion says I had a good response at 10 cm H20 with no respiratory events.
