#188 PRS1 ASV Import Data Failures
Been using a PRS1 CPAP for a few months. Yesterday was upgraded to a PRS1 BiPAP autoSV Advanced due to centrals. Tried SH release and data was wrong. Downloaded the V0.94-1 unstable to try it. Seems that there are some serious bugs in the data importer. I have attached a report printout so you can get a feel of how serious these are. Basically it only imported about 3 hours of the 9 hours of sleep (each session was only 23m 47s long), has an AHI of 95K, not showing any data in most of the graphs, etc. Even the machine settings were not read correctly. Wonder if PRS made a data format change or something.
Machine: PRS BiPAP autoSV Advanced System One
Software Version: 2.0
SH Machine: Windows 7 64bit
SH Version: Build Date: Oct 27 2013 00:22:15
Revision: 6a02809f73ed9376992c72cf2b2ec3a742b12046 (unstable branch)
I would be more than happy to provide a zip of my P-Series directory to a developer who needs actual real data to debug with. I know there are not many who have this advanced of a machine. And I will be happy to test any releases.
Is this a recent x60 series machine?
All Philips Respironics data formats are not publicly documented, and can not be accessed without manufacturer approval and a signed non disclosure agreement (which would mean closed source code importer modules in SleepyHead, and a few potential distribution headaches... I want SleepyHead to be as open and free as possible, but on the other hand I want it to be reliable. I'm still deciding on the best course here).
The 60 series is quite different to previous models, which means the changes have to be worked out the hard way, but I've yet to get my hands on a enough data with some matching encore generated .PDF's to be able to fully work it out.
Most data I've seen so far for these machines has been from well managed cases (as ASV is working as it should), which unfortunately is not very good for working things out - I need fairly noisy data event wise. (I wouldn't wish the situation that generates data that on anyone.)
I did work out the correct location of the time fields and pressure settings in the .001 summary files a while ago, which should be enough to make things make more sense, but I haven't had a chance to implement them in code.
It involves sorting between various machine configurations and cleaning up the entire PRS1 importer, without screwing up support for older machines. To do that I need a very clear head, which I unfortunately don't get very often.
Will get there eventually I promise.

Yes it is a brand new DS960 60 series BiPAP autoSV advanced, their latest and highest end unit.
From what my doc says my complex is so bad he does not expect me to get into the single digit AHIs and my first night on it was an AHI of 17. Still much better than CPAP AHI's that ranged from 20-72. So I will probably have some noisy data for you when you want it. I did order Encore today so I would be able to provide you with not only the raw data files but also Encore .PDFs. I want to help out and make SH the best it can be. It helped me out so much in understanding what was happening on CPAP and I was able to get a new doc and sleep study to finally work on my CSA. I even did a donation to help out as I know that good software is never free (somebody has to write it).
You let me know what you need and Ill do my best to get it to you. It would be best to contact me via PM as I don't monitor this forum much.

Mark,
I have an older Series One AutoSV 950P. I do use the unit in AutoSv mode as I have CO2 chemoreflex breathing disorder which causes arousals, and central and obstructive apnea.
I have Encore Pro 2 on one of my computers with Sql Server Management Studio, Visual Studio and lots of other tools.
If there is anything I can do to help decode the data, let me know. You can PM me if so.
