Really Long Negative Number
#1
Really Long Negative Number
Good afternoon,
Using the latest version of OSCAR (downloaded and installed yesterday).
Also did my first import yesterday, and everything looked normal.
I did another import today for today's data, Went to my overview screen, and I got an oddly large negative number for last night's pressure [Oct 21].
Any suggestions?

Thanks,
Chris

RE: Really Long Negative Number
It seems you switched from APAP mode to CPAP. The statistical data is kept separately,and I suspect that that OSCAR didn't handle the change properly.
I'd like you to zip the entire SD card into a file and upload it to Bonjour's Dropbox so That I can look at it and figure out how to handle that properly. Also I'd like to see data from a recent Autoset to see if it has changed.
Instructions fo zipping are in the wiki: http://www.apneaboard.com/wiki/index.php..._Card_Data
Please send me a PM when you are ready to upload the file.

APAP to CPAP mode in OSCAR or on my machine? Because I haven't changed any clinical settings on my machine.
Otherwise, I have a ZIP file to send you.
Thanks,
Chris

Ahh, Ding! the colour block for the 21st was all one colour, but the tool tip SAYS 'APAP min 6 max 12' -
Definitely something weird here.
I've sent you an upload link for your file.

RE: Really Long Negative Number
For the interested, that big negative number is 24 bits on 1 followed by 104 bits of 0. At a guess that would be the most negative floating point number, the result of dividing by zero perhaps.
Spioch, your profile says you have a Remstar Pro - if that is correct, it suggests the problem may not be in the ResMed loader, which was my first guess. This is useful information.

That is correct.

RE: Really Long Negative Number
I fixed a number of problems that resulted in large, negatives numbers for AHI calculations. I think the phantom date problem could also lead to that result. But I don't recall whether I fixed anything related to pressure. These fixes were in testing-4 or maybe even after that. Sorry, I can't find my notes on when those fixes were made.
The current version of OSCAR is 1.2.0.  We recommend upgrading from any earlier version.

RE: Really Long Negative Number
For what it is worth, I have had the same issue, since SH days.  I do not know if this is a coincidence, but the machine mode setting (only in the Statistics tab) somehow is being set to CPAP rather than APAP and the pressure is read out as a huge negative number.  I have not set the machine to CPAP since 2016, yet over the same time interval, there have been 16 "changes" to the machine listed under the Statistics tab.  If I go to the individual dates of the alleged changes and review the daily data, it shows that the machine is in APAP mode, not CPAP.
