OSCAR showing really weird-looking stop in data

[cathyf]

Last night's data had a really weird artifact that I've never seen before. The flow rate curve and the mask pressure curve disappeared 8 seconds into what the machine scored as a 59-second apnea. The event flag is there floating in empty space! But then all of the other graphs are there still running all through the apnea, and another 9 seconds afterwards, and then there is a short break that looks like I took a bathroom break, and the machine recorded it as a new session.

Is this a bug in OSCAR? Is the machine recording something out of sync that OSCAR is faithfully reporting?

There is definitely something weird there. I'd like to take a more detailed look at your files. Please make a zip of your SD card and upload it to https://www.dropbox.com/request/REp6AH7LCGyeOcXfOokH

Please include your forum name in the zip file name so we know who the file is from.

I posted something similar yesterday.

Same issue here. I'm a new user with Airsense 11 Autoset. Twice last night about a second each. The pressure curve drops to the minimum and then starts ramping up again.

I just realized there is a 22 minute gap in the chart as well. I don't get up in the night. I can accept a power fluctuation gap for a second or two, but 22 minutes??? There was no power outage.

That sounds like an auto stop/autostart

Smart Start is on, Smart Stop is off. Would changing either setting correct the issue?

If you use MyAir, goto to the date in question and look at the Mask On/off field.

Assuming you turned your machine on, and it remained on continuously all night the value should be 1.

If your machine was powered cycled, it will be be 2. If it is 1, then the 2 sessions represented by OSCAR is iikely a data corruption, input or interpretation error.

millstown50 and paulauf: Please create a zip file of your SD card and upload it to our Dropbox. You can use OSCAR to create the zip file; go to Help->Troubleshooting->Create zip of CPAP data card. Be sure to put your forum user name in the filename, and then upload it to https://www.dropbox.com/request/REp6AH7LCGyeOcXfOokH

I hope to discover if this is a problem in OSCAR or in new code in the AS11.

Thanks for your help

Uploaded. I didn't know about the SD card requirement until a few day into using it (thanks to this wonderful forum). Note, there were no instances of dropout in last two nights. We do have occasional light flickers here. I'd also appreciate a trained eye to look at my settings and results as I'm waiting on a phone consult with the VA to set it up ... in two-months! I was just reprimanded by email for changing my settlings without the doctor's permission after complaining that it felt like I has a leaf blower in my face and my cheeks were blowing up like a chipmunk. I replied politely stop changing my settings and we can discuss changes if they recommend something. I'm waiting for their response.
