jolycu,
Here is a link to encore basic software.

It's not as detailed as Sleephead, but should give same basic information.

When you say your husband took his mask off, could be why data is messed up.

This makes no sense. For example: Where's the flow data?
The statistical summary has a median tidal volume (last night) of 220 ml.
Who breathes that shallow?
A median respiratory rate of 5.6 per minute? Should be around 15 bpm.

Software bug. Machine says AHI is 38 that is what it is, regardless of what SH says.
Try uninstalling sleepy head and reinstalling ng it clean.
Also, you can get a new SD card in case the old one is corrupted but i doubt it is.

RE: 0.00 AHI but graphs look weird
So..... about that AHI of 38 Huh

Questions:

Did you ever increase the minimum pressure (I think that was discussed in a previous thread?). Since this SleepyHead report is messed up I'm not assuming that it's showing the correct pressure settings.

How much of that AHI is centrals?

I'm hoping that you always lock the SD card before you insert it into your computer to transfer the data to whatever software you're using. That way any sort of glitch won't affect the data.

(Remember to UNLOCK it before putting it back into the machine! Wink )

If you get a new SD card and plug it into his machine the machine should write all the data it has to the new card.

Th PR 560p unlike resmed doesnt care about locking the card or other files written to it.
Same machine i have i never lock my or wifes card.

Had same thing go on once with SH. But not Encore.
Just uninstalled the reinstalled SH took care of it.
I still run Encore slso to dbble chk SH.

RE: 0.00 AHI but graphs look weird
Thanks everyone for the insights. Kaiasgram, yes, I did increase the pressure. We started one night at 7.5 but he was thrashing all over and pulling the mask off. I would wake him up and put it back on, but after the third time, I dropped it to 6 which is where it's at now. I think we'll leave it there for a week or so, then bump it to 6.5. The machine shows a 7 day AHI of 8.1 and 30 day is 7.7. Here's what Sleepyhead shows for November:

I will download Sleepyhead and reinstall and also download the Encore Basic software for comparison.

RE: 0.00 AHI but graphs look weird
I can only think of 3 possible reasons for this(since prs1 writes the
Waveform data to the SD card directly).

1) you did not insert the SD card properly during the night with spotty waveform data.
2) your SD card is faulty.
3) Some virus has corrupted your SD card data when it was in the computer.

Started APAP 4-20, Closed range to 7.5-14, then straight 8.0 w/ Aflex 3
RDI always below 1. But sleep much much better at straight pressure.
Started on F10, Tried Quattro Air successfully. Finally settled on P10.

Do you have aflex enabled?
With aflex on a min press of 8 should be very easy for anyone to tolerate. Thats probably where his min ressure should be anyway.

Make sure your card looks like the "unlocked" image.

Also, make sure you insert it into the machine until it clicks.
