Data that OSCAR has never seen before

Data that OSCAR has never seen before
Upon using my DS BIPAP AutoSV, I got a warning when loading my SD card that says:
"Your Philips Respironics BIPAP AutoSV (900X110) has generated data that OSCAR has never seen before"
"The imported data may not be entirely accurate, so the developer would like a .zip copy of the machine memory card and the matching Encore .pdf reports to make sure OSCAR is handling the data correctly"

FYI, apart from many new and awesome graphs that I do not get with my Resmed Aircurve 10 ASV machine, I don't see anything highly unusual other than perhaps a lot higher AHI calculations which is normal when using a DS machine as compared to a Resmed.
I have attached a screenshot of today's data which looks normal to me.

At any rate, can someone please let me know whom I should send the .zip folder to? and what is the "matching Encore .pdf files"?

Thanks

I encountered the same message some time ago and sent in a zip of my SD card. I also learned about another “feature” of the DS Bilevel AutoSV reports. The mask pressure reporting maxes out at just below 16.

I see that your machine is reporting mask pressure up into the 20s. What firmware version do you have?  Mine shows V1.01.

Make sure you don't have your max pressure setting or your PS max setting at about 16. That maybe the reason.
My firmware version is V1.0.6

RE: Data that OSCAR has never seen before
No, there is a bug in the 900X: if you look at the mask pressure graph, it will never report pressure above 15.875 cmH2O, even if the pressure went above. The settings, however, will correctly show higher settings (such as 20), as will the reported IPAP high/low/average over each 2-minute interval.

The "data OSCAR has never seen before" message pops up any time OSCAR runs into values that for which we don't have test data, and that evolves over time, so data which triggered that message in OSCAR 1.2 won't trigger it in 1.3 (assuming somebody sent us data to verify).

Most often it turns out to be totally benign, as in your case: OSCAR was doing the right thing, we just previously had no way to confirm it. Occasionally it does reveal a mistaken assumption, which then results in a fix to OSCAR so that it's accurate.

So your imports are fine. We simply had never seen a timed inspiration of 3.0 on a 900X before, nor had we seen apnea alarms or low minute ventilation alarms. OSCAR doesn't currently do anything with apnea or low MV alarms anyway, and it turns out it was handling the 3.0 correctly already. The next release of OSCAR won't complain about these values any more.

Thank you for the sample!

Well, what do you know? I looked more closely at your screenshot (and data) and realized that your machine is reporting mask pressure about 15.875. I cross-checked it against some other 1.0.6 samples I have vs. 1.0.1, and indeed this bug in the 900X was fixed in firmware version 1.0.6.

Yes it was Big Grin
I just didn't know that there was a bug because my machine came with 1.0.6
