Dreamstation ASV missing data
Has anyone had missing flow rate and inspiration/expiration in their OSCAR download? I'm using OSCAR v1.1.0-testing-4 (a8dc05c3). Data is also missing from Encore Pro 2. I was asleep during the time in question but I'm sure that I was breathing! I'm wondering if something is wrong with my machine or SD card.

RE: Dreamstation ASV missing data
That's very interesting. There are clearly other events and data flagged during that time, but no flow graph.
My guess is that there was some corruption in the waveform data file on your SD card, but I'd either need a copy of the debug log (after rebuilding the data for your machine) or your SD card to confirm.

I can send you either or both. I don't know how to do the rebuild/debug log unless you tell me how. I can send a copy of the SD card data if you tell me where to send it to you.

RE: Dreamstation ASV missing data
I just had a similar experience occur on a newly acquired Resmed Aircurve. I have a gap in both my Inspiration and Expiration times. It seems to coincide with me turning off the A10 at one point and it being turned on at the other end. The gap starts at 01:40 and ends at 07:00. All the other graphs indicate usage in between those times. So far, this has been the only day to display this anomaly. Since OSCAR only reports on the data, I would be suspecting the machine itself.
Oh!, I did clear the data and re-import several times just to make sure that this was caused during the import.

Simplest then is to upload a .zip of your SD card to bonjour's dropbox: https://www.dropbox.com/request/6VeFzBXa4qZ37EgphL5b

RE: Dreamstation ASV missing data
I have the same problem. It may be related to the firmware version of your machine.
On my machines, recently upgraded to V1.06, the patient data appears to have been moved to a different folder labeled "D" under the P0 folder.

RE: Dreamstation ASV missing data
this sounds similar to the problem I posted about in the beta test forum that pholynyk is looking into.

RE: Dreamstation ASV missing data
Aha, found it. I think this was already fixed in beta-1. It turns out that sometimes when the machine hits 500 files in a folder, it splits the waveform data between the old folder and the new folder. Prior to beta-1, we were dropping the remaining waveform data.
You'll probably see a similar drop-out at the tail end of August 11.
