First night with OSCAR, what does it mean? - BB63 - 07-27-2020
Today I got my much awaited SD card reader and I saw my own data in Oscar for the first time!
My interpretation of the data shows I don't have a serious sleep apnea problem although I could very obviously be incorrect.
I notice 1/3 of the events happened after I woke up in the morning! And, I'm not sure why the leak rate shows zero most of the time-the vent holes on my mask would have to be 100 percent plugged up to make that happen. And, I have some terms to look up in the glossary.
Would appreciate some comments from the membership regarding what the graphs actually show.
TIA

You certainly don’t have a severe apnea problem, but do yourself a favor and turn on EPR. It appears you are using a limited auto pressure from 11.0 to 12.2. I’d recommend you add EPR full time at 3 and perhaps open up the pressure range from 9.0 to 14.0. The EPR will make you much more comfortable and will reduce flow limitation. Try it you’ll like it.

Sleepriders suggestions should help with the flow limits and improve your comfort with the machine.

Wow, based on my first look at the data, I already changed the pressure with a range of 9 to 13!! And, I changed the Antibacterial Filter setting in the CPAP. I can't take to much stock in a single nights worth of data, so time will tell.
I'm not sure about the EPR change, I had a recent experience with a hospital supplied CPAP and they refused to disable the EPR or even share the settings with me. But, I'll try it sometime soon.
TY all.

I just zoomed in on the 3 to 3:15 AM data. It is very telling I think. During this period I had 9 events, more than a third of them happened during those 13 minutes. I posted the zoomed screen capture. To me, it looks very much like I might have woken up (arousal), suspicious since I had just gotten to sleep 30 minutes earlier.
I should note that I live in severe Gout pain and have long suspected that I wake during my sleep due to the pain. At times I wake up screaming from trying to roll over, so I do know that pain can awaken me. Yesterday the pain was very severe.
I also moved the AHI graph so it could be seen on the same time axis as the flow rate. And, the zoomed in data looks a lot like the data I get when I am fully awake. I'm wondering if I might have fallen asleep, but woke up a little later....but with no memory of the awakening in the morning when I got up for the day.
Is this possible or a reasonable hypothesis?

Do not change the antibacterial filter setting
The antibacterial setting should be off, unless you have a special Resmed Antibacterial Filter between your machine and mask. Turing the setting on will adversely affect the machine pressures
