not getting good sleep

I had it changed to 12 when I couldn't tell a difference. 4 weeks on 12 and still no difference. I read on here last night how to adjust the pressure and moved it to 13. I had an AHI of 1.2 last night but I feel horrible this morning. Like a bad hangover and hit by a truck all at the same time. Does any body know what I should try next. Sorry if this is the wrong way to do this. I have never tried to post to a forum. Thanks

Wallace, go into "Member Account Help Forum", there's are many "how to" threads there to help you.

Not sure you'll get a lot of response to your questions from this older thread, but if you are not using software to track your progress, it would be hard to give advice on pressure changes. Your AHI is good, but if your not feeling well, then there is something else going on. If you download SleepyHead, someone could look at your charts and help you.

I think intense dreams can falsely report CAs. I can remember waking up and gasping for air after dreaming I was drowning. I wasn't on CPAP then, but I'm guessing SH would have reported it as CA. I think the software can be easily confused by dreaming.

That may not be always the case. The at-home study I took last year was able to identify and distiguish between CA/OA/hypopneas, and track respiration and pulse. It found exactly two CAs in my particular case, but an AHI of 55.7, primarily OSA events. There was also a canula, so it was probably looking at something with the makeup of my exhaling, such as CO2 levels.

Certainly not as accurate as a full PSG or split study, but much less expensive and a good way to initially diagnose sleep apnea and its makeup of different sorts of events. Plus, you are in your own bed, and it does not carry the intimidation factor that keeps many from obtaining therapy.

Many Dr.s and insurance co's agree that this is a good first step. It inexpensively rules out those who do not meet the threshold of SA, and can give the doc a starting point for the therapy for those who do. Often, a full study is also eventually in order for those who do meet the threshold.

My best guess would be that the software can be confused by the changes in breathing which result from emotional and physical reaction to the experience of dreaming.

Occasionally, but not often, I have clusters of CAs during REM periods. While that may be something flagged by the xPAP due to a normal change in breathing during REM, it seems to make more sense that it may be flagged due to changes in breathing resulting from dreams while in REM. Maybe both.

And yes, I agree that these are probably false positives, and not a true representation of a CNS event where respiration was halted due to a failure of the system to invoke breathing.

The machine and the software only care whether your airway is open or obstructed. If your airway is open when an apnea is in progress, it will score a CA. If the FOT finds the airway closed, the machine scores an OA. The determination only depends on the patency of the airway.

Do your dreams cause your body to mimic what is in the dream. Could be but when you stop breathing, it is an apnea and the machine will test whether your airway is open or not and score the apnea accordingly. The machine is not confused. Its job is straightforward:
1. Sense the apnea
2. Classify the apnea

First, the systems, short of the Timed CPAP or ASV, are not designed to "invoke" breathing. Their job is simply to splint the airway open so that you can breathe. The reason for these machines to discriminate which apneas are CAs and which are OAs is so that they can raise the pressure on OAs but not CAs, since increased pressure will not help CAs.

Tyrone, since you have not and apparently can not produce any support for your point of view on "false positives" and you think that none can be garnered for the opposite point of view, I am going to give you a reference to a scientific article that has been peer reviewed prior to publication like all good published scientific articles are. The reference for you is, "Central Sleep Apnea Detection and the Enhanced Autoset Algorithm". It shows that the FOT which has been in use since 1950 and has been tuned for apnea type detection, is actually quite accurate.
