How hard was it and how long did it take to optimize the pressure, AHI, and "sleep quality"? What was your pressure, AHI, and "sleep quality" before you detuned? What was your pressure, AHI, and "sleep quality" after you detuned?
I would say taking control of your xPAP therapy is a personal decision, best with the consult of your sleep doctor. He gave me the all-clear after I showed him the data I had, and I talked to him about it and he knew I understood how to personally manage it.
In the beginning, my pressures were 5-15 cm H2O, nearly wide open, because the Dr. didn't know the cause of my apnea nor did we do a "titration study". He had some faith in the machine, I think. Later, I had to see a pulmonologist regarding increasing centrals. They wanted me at 10-20 cm H2O range. I tried a max of 20, but it was a NO-GO. I could not tolerate it, physically, and it destroyed my ability to sleep. So, I went back to 5-15. I started to have clusters of apneas and I think it was Pugsy that suggested raising the minimum. Since I was used to the machine, I was able to increase the minimum gradually to 7.4 cm and it helped but then I got gopher cheeks right away as I went to sleep so I backed it off a bit to 7.0 and started using a mask liner. That helped a lot. Now I don't even notice the mask as I doze off. I then tried easing off my max to avoid disturbing my sleep when the machine went to max. That helped too. So, right now I'm 7-14 and doing well.
What are the benefits of getting your Zeo data real time through the cable? How is this better than downloading the data from the SD card? Wouldn't the data be the same? Since you're asleep, how does real time data help because you won't see it until after you wake up in the morning anyways?
I get more detail with the individual brainwaves I collect from the hacked Bedside. I can see where the Zeo classifies some Deep as something else, but with the individual waves I can tell it is more like Deep. Since it is real-time and I can do things with our software in real-time, in theory I could have our software do something during the night while I sleep, like wake me up and alert me to some condition, though I haven't. So, the biggest benefit is more detail and a better view of reality, rather than an attempt to do a man-made interpretation of sleep stages. You see, there is no such thing in nature as discrete classifications, but a continuous process that our brains go through during sleep. Sleep stages are a man-made construct to try to interpret a natural continuous function.
Look at the chart below and look at the "doughnut holes". Only a part of the first is classified as "Deep", but I know that there is some mind/brain process going on during that entire period of the "hole", easing into it, easing out of it, not "snap... hey, you are in Deep!... Snap! Hey, you are in Light!" No, that's not the way Nature works. Later, another "hole" appears and I know (or guess) that is a similar process going on, but to a lesser degree, but hey, the Zeo classification says that is "light and REM", but really I can see the truth better with the waves.
