RE: OSCAR showing really weird-looking stop in data
I wonder if the functions that write the flow rate and mask pressure out to the files have some big lag, and the write hadn't happened when I turned off the CPAP, and then the data was lost?
The other curves got logged, and the event got logged.

RE: OSCAR showing really weird-looking stop in data
I came here to post a similar event with my machine as well. In my case I do have ramping on and it shows the machine stopping and restarting with ramping. It's happened twice now, once about a week ago at which point my supplier gave me a loaner to try for a week. The second was the first night back with my original BIPAP. My machine is an Aircurve 10 ST.

Hi Absolutzero273! -
 Do you have Smart Start or Stop turned on?

On a good note I have been struggling with getting my AHI down and stable since the beginning of the year and now that I went back on the ST last Friday things have significantly improved the last 3 nights. I really can't explain why (only change was switching from S mode to ST mode), but I'll take it!

Are you sure that wasn't you stopping and restarting the machine?
What does the close-up look like?

RE: OSCAR showing really weird-looking stop in data
Also what I saw I don't think is a stop. It looks to me like the file writes for the flow rate and mask pressure curves just stopped writing data into their files, while all of the other data streams logged as normal. Then there was a stop -- me turning off the machine for a bathroom break -- and afterwards things came back and looked normal.
I wonder if it's bad sectors on the SD card?
