I don't think they do a titration test along with the Pes test. I could be wrong.
So even if you do have UARS confirmed and maybe you do need more pressure for the UARS stuff than you do for the OSA stuff (not uncommon for UARS patients to need a lot more pressure) you would likely still have to do the titration at home by simply trying more pressure and trying to measure how you feel (the machines reports won't help you much in terms of evaluations).

I read somewhere a long time ago from a book or article written by one of the well known sleep doctors that he thinks everyone with OSA most likely has some component of UARS also going on. Makes sense to me if you think about it.
Please don't ask me who said it...that was years and years ago and I don't remember who it was. Might have been Barry Krakow, MD...but I wouldn't put money on it. He is well known for being aggressive when treating even maybe cases of UARS and will actually try to do in lab titrations to find optimal pressures for UARS patients.

I checked and they do the PES testing only half of the night. They wake you up and take it out and do titration afterwards.

But if more pressure is needed for UARS then that is what my machine is trying to do at night. It's already increasing pressure when no OA are present.

So I don't know if another sleep study with PES is worth it. The only thing they would do is confirm UARS and then increase pressure probably. But most nights I'm OK at minim bipap pressure IPAP8 EPAP 4 PS4. But other nights it shoots up to ipap 16 or more.

But here's the deal with the half night thing...after they remove the Pes device they have no way to measure if the pressure is holding the airway open or not enough. It becomes nothing more than a normal titration study.
They have removed the Pes device...no way to know if whatever pressure they use is enough to keep the airway open enough to resolve the UARS issues. If they could...everyone who had an in lab titration would also get their UARS supposedly fixed.

Me...I wouldn't do the Pes sleep study.
I don't just have to know with 100% certainty. I already know I have OSA and need cpap.
I would just get and use a machine that could auto respond to anything it didn't like.
If I suspected UARS and despite the machine doing its thing and I still slept horribly with really good numbers on paper...I would do my own titration and simply increase the EPAP in stages to see if it helped or not in terms of how I felt in general or slept.

I don't care why my machine increases the pressure...I am just happy it does and I am doing fairly well in the treatment of OSA side of things. Besides...not like I can do much about it anyway. I long ago decided to make a point of not worrying about stuff I don't have any control over.
