What should I expect after titration study?

I've been using my CPAP for about three weeks. Compared to what I read here, I've really had no problems adjusting to it, even from the first night. I keep it on all night, haven't noticed that I really need to strap my mouth closed, and haven't noticed any other leaking.

My doc started me out at 8 (is that pressure in cm H2O?) I have a feeling that isn't enough. I still wake up several times a night and I don't feel as rested in the morning as I hoped to feel.

I've toyed with the idea of increasing the pressure myself, but I have a titration study in about a week and I just decided to wait until then.

Do you think the doc will increase the pressure after the titration study? I guess I'm asking if 8 is pretty low.

the pressure is determined by the PSG titration study. They select the pressure while sleeping in the supine or back position, this where SDB should be most severe.

They select the pressure as you sleep the higher the pressure goes the fewer events will be seen. So finding the correct pressure is not a guess by your doctor, sometimes it is but most times it is not.

But a night at the sleep lab is just that, one night, you could have a rare good night which would skew your results and required pressure. It is why autopaps are good, doesn't matter it will find the ideal pressure needed from night to night as your needs change.

Your doctor won't know you have changed anything, machine doesn't keep any kind of a log unless it is a 420e.

The logical thing in your case would be to bump up pressure to 9cm and compare how that is to your titration next week, go by how you feel not what the pressure is.
