Can use of cpap actually cause sleep deprivation ?

Don't listen to a word any of these guys have said about a fixed pressure of 12. That would be a recipe for problems. Your 95% pressure is 13.5. This is your self-titrated fixed pressure.

WC - you don't understand how things work and should definitely not be dispensing medical advice until you do. "Those guys" know what they're talking about and you need to stay out of it.

And how did you come to that conclusion?
Do you understand the definition of these 90/95% numbers?
What would you suggest someone to use as a fixed pressure if one night their 95% pressure was 18 and the next night it was 12 (and leaks were NOT a factor)?

Not my conclusion. I will link the report once I find it again. Thank you for the correction though. The 95% pressure is supposed to be over a few weeks, and not just one night.

Where did you come up with THAT conclusion? If it's not yours, please cite the source. The reports give the percentage numbers every night for that night. It will typically vary every night.......especially the wider the pressure range one uses.
Using a wide open pressure range is usually a recipe of disaster.
From the vast majority of APAP reports I've seen, a pressure somewhere between the "Average pressure" and the "95% pressure" is usually a better fixed pressure setting. Too many things unrelated to actual A/H events can skew the 95% pressure result, and therefore isn't as reliable to choose.
And, the reports need to be thoroughly scrutinized to study what happens during the night and why pressures change.

Keep in mind that there are other causes for sleep deprivation, but yes, I think Cpap can cause issues for awhile until you are comfortable with the setup. My late Dad was kept awake by his oxygen concentrator for a couple of months. After awhile, it actually lulled him to sleep. It's the sound, or the pressure, or the feeling of the mask. It could also be a completely different cause. I have RLS. It coincidentally worsened at the time that I got a cpap. Cpap didn't cause it. Even though it wasn't evident in my sleep study, the titration showed that I was woken by RLS. So, it could be something that you don't have occurring all the time and it just happens to bug you now.

I'm currently getting used to a new mask (Dream) and I keep waking up. Low leaks, so I know it's working for me, but I'm not used to all the sound.

I actually felt more tired and a bit "hung over" when I started cpap. It took several months until I started feeling half way normal.

I'm an engineer, so I understand the definition of percentile.
