Sleepyhead says "Summary only"

[AMK]

After using Sleepyhead successfully for over a year, I'd last downloaded my data on Sept 3. I went to download it today and I see that even though the SD card is almost empty, on Sept 6 it started only recording the summary, no data. I now have a whole month with no data. Does anyone know what has gone wrong? Thanks.

Was the SD card in your AirSense 10 machine the whole time or maybe it wasn't inserted fully?

You get summary only data if the SD card either isn't in the machine or it maybe isn't fully seated in the cpap machine.

Thanks for the reply, Pugsy. I had put the card in on Sept. 3, and it had recorded data until Sept. 6. I am not sure how the card could have unseated itself. The other odd thing that my DME refuses to think is odd that on the very day my machine stopped recording data, this is how my AHI changed:

(Sorry, I cannot remember how to post images here and I hope that is sufficient).
I know my AHI is excellent, but why did it change like that at the same time the card stopped recording data?
I will try a new card.

Don't know why the machine stopped writing to the SD card if it was in the machine properly.

If a new card doesn't resolve the issue then I think I would probably reset all the data on the machine and start totally fresh if it were me. You lose the past data that is stored on the machine but you have it in the software and on the old card.

It wouldn't be impossible for the SD card to up and die...or it wouldn't be impossible for the machine to just quit writing to the card but that's a very remote possibility.

Finally....I think I would also maybe confirm with ResScan that there's no other data available....just in case SleepyHead has decided to act up.

My wife's Airsense10 "Autoset for Her" some times does not get all the information, so far unplugging the machine and plugging it back in fixes it. It only happened a couple times in the past year. The first time we thought she did not put the card in correctly but now believe it is her machine.

The other odd thing that my DME refuses to think is odd that on the very day my machine stopped recording data, this is how my AHI changed:

There does seem to be a bug in some versions of Sleepyhead with some machines (ResMed that I'm familiar with) in that if the Detail Data is not available, then the AHI Summary Data as reported by SleepyHead will be incorrect. The AHI as reported correctly by the machine and in ResScan will be consistently higher or lower than that reported by SleepyHead. I don't remember which way, higher or lower.

I'll see if I can find the thread where it was discussed.

[AMK]

Pugsy, yes, ResScan showed the data! I downloaded and installed a newer version of Sleepyhead and it shows the data. I can't imagine an explanation for why Sleepyhead would have stopped working on Oct. 6. But I have the data. PaJoe, just for laughs I replugged the unit, figuring it wouldn't hurt. Thank you both for the responses! And I see that Jay has responded......yes, now that I have the data in the new Sleepyhead, it looks normal. Thanks for that info; I'll remember it if this happens again. I am grateful that my machine was fine and this was some kind of Sleepyhead situation.

And as a follow on:
According to this thread: viewtopic.php?f=1&t=105363&st=0&sk=t&sd=a#p996662, it looks as if SleepyHead reports a significantly lower AHI than actual if there is no Detail Data. This would be consistent with AMK's results.

[Pugsy]

SleepyHead can be a bit buggy or flaky at times.
Glad you got it all sorted out and it was something as simple as a software issue.

For the most part SleepyHead isn't all that buggy and the little bugs that are found are minor bugs that really don't hurt much but every now and then SH just lives up to the "it's Beta folks so expect some bugs".
That's why I always verify with the name brand software before I go worrying about the machine or the SD card.
So if possible (I know you non Windows users can't) use Encore or ResScan depending on which brand machine you are using to confirm the issue or not. It might be SH and it might be something else but using the other software to rule something out is very easy to do.

[AMK]

Yes, definitely a lesson learned. I'm going to make a file with all this info so I don't forget it. Jay, now I know why the DME thought I was out of my mind when I was asking why my AHI dropped like that.

[PaJoe]

Sorry I did not better explain, with my wife's machine, it just stops writing to the sd card, although unplugging it for a few seconds before plugging it back in seems to get it writing to the sd card again, data that was lost does not come back - it does start recording at that point, so we do not actually see all the data again until after she has another sleep session.
