Strange Graphs in SleepyHead

[rx77310]

I'm getting what I think are strange graphs in SleepyHead (v0.9.8-1(testing)). Instead of a single line on some of my graphs I get multiple. I have attached images. What do you guys think?

I think you should use the rebuild data option.

I don't know the answer but have a couple of ideas. I like Mark's suggestion. Are you using the OpenGL or BrokenGL and is the graph the same in both?

I was using OpenGL. I just tried rebuilding the data in both OpenGL and BrokenGL and the graphs still look the same.

Was that just on one night or do you have the same thing on multiple nights?

Only for last night I believe. Actually it looks like I get multiple lines for leak rate on multiple nights.

Well, I can quote a line from "My Cousin Vinny" about something being broken but it might not go over so well.

Post back tomorrow after tonight's data. Curious to know if the same thing happens.

[quiescence at last]

I have had this happen to me about 4 times in the seven months I have been on therapy. I have the same model and make as you (I think).

I noticed that the nights this happened, I yanked the card out only a few seconds after I stopped the machine.

Recently, I have waited at least 30 seconds, and often more than a minute after shutting the machine off. I do not know if this is at the root of the problem.

I haven't tried the SleepMaster wireless transfer method. I may, someday, though.

Good luck,

Upon closer inspection it looks like the leak rate graph usually has two lines. One for leak rate and one for total leaks. I don't know what the difference is supposed to be between those two lines.

The pressure graph looks like it usually has one line.

In the attached image in the original post, the pressure graph has 2 lines but more parameters are listed than usual. IPAP, EPAP, and pressure are listed. Usually only pressure is listed.

In the attached image in the original post, the leak graph actually has 3 lines, where only two parameters are listed, leak rate and total leak rate.

So far it looks like this happened twice since owning and using my CPAP for about 2 and 1/2 weeks. I'll try the above suggestions of waiting a bit before removing the SD card.
