Running the machine with the mask off may show up as a leak. It won't show an apnea.
If you're awake, the apneas don't really mean much. Even a "normal" person will have "apneas" while awake and they aren't harmful to your health. So, if you take a lot of time to go to sleep, or wake up and take a while falling back to sleep, you'll get some false readings that way.
If I look at my own data, sometimes I see something the machine calls an apnea or hypopnea that I don't consider to be "real" apneas, but something was going on with my breathing. There usually aren't enough of these per night to worry about.
I find it useful to look at the airflow waveforms, not just the AHI and event counts. Long apneas are more meaningful than short ones. Completely stopping breathing is more important than events where you are still getting some air into your lungs.
Even when you consider these factors, the overall numbers are usually pretty accurate and the false readings are small enough to not matter. Some people obsess over reducing their AHI from 2 to 0. That's usually meaningless in terms of health.
Get the free SleepyHead software here
for information on the main alternative to CPAP.
If it's midnight and a DME tells you it's dark outside, go and check it yourself.
ok, I gotta admit something embarrassing here...
After I posted this thread, I called my oldest brother. He is 12 years older than me and he's been encouraging me in my therapy. My goal is to avoid some of the things he has faced.
Anyway, he clued me into the fact that I haven't been pulling up my 'Detail Graphs' in ResScan. lol, apparently this is like 80% of the most important info because it allows you to see when and to what extent the events are happening through the night. I have only been looking at the 'Statistics' page. My bad. This, of course, shows the challenges that I face as a 'underground' user versus someone who gets to meet with a clinician. Of course, the medical industry feels that only a licensed clinician should be using ResScan and interpreting it to the patient. I am sure most here dissagree.
Thanks for the links and the advice.
Which software do you guys prefer? ResScan or Sleepyhead or what?
Side note: It was very hard at first for me to fall asleep with my CPAP machine going. Especially before I got my S9. I have always been a fan of audio books, while driving, walking, and mindless work like mowing the lawn or gardening. So when I started this therapy, I started listening to audio books as I tried to fall asleep.
I have done the Hunger Games Trilogy (Loved the books, hated the movie), all the Game of Thrones books (I am in the process of editing a clean version of the TV series for my teen kids to watch, two episodes done so far. I feel there is little chance that Martin will finish this series before his death. lol, maybe CPAP therapy will help him live long enough to prove me wrong.),
about 26 Deathlands novels (been a fan years before that one movie came out that was horribly bad, that series would make an awesome Sliders/Quantum Leap/Stargate type of show with the right cast and budget),
John Dies at the End (read book first then saw the movie and it did not translate well at all),
World War Z (the book was great, but saw the trailer and boy is that movie going to suck),
The Revolution by Paul,
End the Fed,
Puppet Master (very different than the movie that I liked),
and I am currently going through some old Ray Bradbury stuff (I really enjoyed the Martian Chronicles growing up).
Any tips from you guys as to what you use to help you fall asleep while using these mini iron lungs? ..besides marathon sex, alchohol, or sleeping pills? (those are a given, in fact all three at once and you just might not wake up)
Google "sleep hygiene". Listening or reading books in bed is not a good idea. Especially if your body is accustomed to being active while listening to them. It's not going to want to go to sleep.
Sit up during the day with the mask and machine on. This will help you get used to the sensations.
I much prefer SleepyHead to ResScan. I think it goes more to the point rather than concentrate on compliance. I used both for two months and finally stopped using ResScan.
OT: I tried to read World War Z but just could not get into it. Interesting concept though, of how it was written.
