RE: Appreciate some help profiling these CA events
He prescribed an EPR setting? A question to ask on your followup would be why?

I thought again about your graphs. You have a remarkably narrow range of pressures that you seem to need, at least based on that one night's data. Again, if it were me, I would give serious thought to simply raising the minimum pressure setting to 8. It's more than you typically need, but just barely so, and will guarantee that you are always at a pressure that curtails your apneas.

As for your doctor, what do you think he would prefer: blind obedience to his recommendation (that was based on one night's data in a foreign environment), or participation in their treatment by a patient based on multiple night's data from their home environment and well reasoned analysis? You could even call him, explain the situation, and get his concurrence.

RE: Appreciate some help profiling these CA events
Curiosity got the better of me and I went ahead and turned my EPR setting to 0 last night. It noticeably affected me while I was trying to fall asleep, and will need to get acclimated to breathing without EPR. It's not that I felt a pressure difference (my starting pressure is the minimum anyway), but I had some synchronization issues as I feel like the machine somehow induces me to inhale when it wants me to, as opposed to when I want to. It's almost like it wants my breathing to be perfectly periodic, on a set frequency. To test it, I half-heartedly tried to pause my breathing after an exhalation and found it really difficult to do so. I don't know what that has to do with EPR, but it's unsettling. I did notice significant tossing/turning in bed last night and not as many pressure increases in the data. There were only two "humps" in the pressure graph, spaced very far apart. I usually have 5 or 6.

Interesting results: the flow graph showed far fewer flow limitations and there were no hypopneas or apnea events recorded. None. AHI was 0.0. Blink

Too good to be true? I'm going to try again tonight... see if anything changes in the data.

The pressure graph peaked at 10.0 at one point. Mind you, I was titrated at 5 in the lab Rolleyes If I had a straight CPAP machine and didn't know anything about checking my data or changing settings, I presume I would be receiving insufficient pressure at many times throughout the night.

Yeah, right. Based on one night's worth of sleep in a strange place on a strange bed all hooked up to wires, and people wonder why their home sleep isn't satisfied by their titrated pressure.

I was titrated at 13. I've recently been playing with the Auto-trial mode of my CPAP, and it typically takes my pressure to a 95% value of around 17. I foresee a permanent adjustment to my treatment pressure in the near future.

I think it's just your brain adjusting to the fact that it doesn't have to keep waking you up to breathe anymore.
