Oscar sessions seem wrong

[Crimson Nape]

The Wiki article is specifically referring to the AHI graph in OSCAR, and not the reported value of AHI for a sleep session.

[pholynyk]

The AHI graph is the running count of events in the previous hour.
The AHI the doctors (and OSCAR in general) is referring to is the total events divided by duration, be that day or session.

The AHI graph only gives some indication of how clustered the events are, and you can see that from the flags chart at the top of the graphs. It's a waste of screen space IMO.

I was worried and confused for a while.

I believe I get it now.  Don't look to closely at the AHI chart, the best information for the AHI is the value in the orange banner.
Also, since all AHI are calculated the same, the statistic view is a good place for me to check my progress.

Right?

My progressive curve told me that I was not doing to good.
I made a table of the AHI values the statistics give per week. See screenshot.

So, Oscar is telling me I am not doing very good in the long run because, except for one week, the AHI keeps going up.

I will bring this to the Main Apnea Board Forum

I'm looking for the definition of the terms RERA and FLG found in Oscar Detail export csv.

I searched the Oscar help in Wiki and found limited information.

What are these terms?
What are they used for?
What would be acceptable values?

I do have some info but I would like to be thorough.

Thanks

EDIT
I have found the way to find all posts with the info I am looking for.
Please disregard this post, I will repost if I need more info.

There is an options in File / Preferences to "Auto-Launch CPAP import when opening profile." Do you have that option set (checked)? If so, please turn it off (uncheck it).

When you could not load the last session for the day, you were importing from your SD card copy, right? Had you copied the actual SD card to the copy before importing the data?

If you can repeat this failure to import problem, please do so, exit OSCAR, zip the OSCAR diagnostic logs and upload to my Dropbox folder. Please include your forum name in the zip file name so we know who the file is from.

It happened again, more than once.

Had new data on SD card.

1. Put the SD card in the laptop.
   
2. Opened Oscar.
   
3. Selected:   .../Oscar/Welcome/CPAP Importer.
   
4. Message popped up saying already up to date with CPAP data.
   
5. Made zip of diagnostic logs (DanEm-OSCAR-logs-A.zip)
   
6. Selected:  .../Purged Current Selected Day.
   
7. Selected:  .../Oscar/Welcome/CPAP Importer.
   
8. Data was successfully imported.
   
9. Made zip of diagnostic logs (DanEm-OSCAR-logs-B.zip)
   
10. Uploaded zip files to Dropbox

On Oscar's graph for pressure there are 2 lines, top one is Pressure and bottom one is EPAP.

Wiki terms definition says:

EPAP - (Expiratory Positive Airway Pressure) - The pressure prescribed for the expiratory (breathing out) phase of an individual on Bi-level CPAP therapy for OSA (obstructive sleep apnea). 

My machine is not a Bi-level (yet). What is the difference in EPAP meaning for my AS11?

GuyScharf did you get the log zip files? Anything new on the importation glitch?

[GuyScharf]

It's just a terminology difference between CPAP and Bilevel machines. The formulas are, with terms on the other machine shown in parentheses:

On APAP machines, you set Pressure and EPR. EPAP = Pressure (IPAP) - EPR (PS).

On BiLevel machines like the VAuto, you set EPAP and PS. IPAP (Pressure) = EPAP + PS (EPR).

I've passed the import question on to pholynyk.

I have looked through the log files. Although they are inconclusive, there are hints for further work.

There was a time when the rule for OSCAR was simply "import once after the end of day". We have tried to find ways to relax that rule, but it remains a good rule of thumb. Importing after each sleep session was not in the design parameters of SleepyHead or OSCAR.

What I saw in the debug logs gives me some ideas to work on to enable your desired work flow. It won't show up until the next revision of OSCAR, if I can make it work out.

It is OK.
As long as purging the last day before importing is not something I should not do, I can work with this.
Thank you pholynyk.

Is there a place were the colours used in Oscar's Overview are explained?

I tried Oscar Preferences, found nothing about this.
I tried Wicki but no luck.
