Where are my SleepyHead Graphs?
I've been using my Respironics System One for five nights. After the first few nights, I had a bruise on the bridge of my nose and I switched to Respironics Nuance nasal pillows for the last two nights. They're much more comfortable.

I was using SleepyHead for my Pulse Oximeter (CMS50D+) for the past few weeks, and now I'm using it for both the APAP and the PulseOx. For the past two nights, some of the the SleepyHead graphs are missing.

In the Daily tab, for the first few nights, I can see:
Event Flags
Flow Rate
Leak Rate
Resp. Rate
Tidal Volume
Minute Vent.
Insp. Time
Exp. Time

For the last two nights, I can now only see:
Event Flags
Leak Rate

In the Overview tab, it says data missing for the past two nights for:
Resp. Rate
Tidal Volume
Minute Vent.

I'm using Windows 7. I downloaded the latest version of SleepyHead (0.9.6) and installed it to a new directory (folder). I re-imported the data into the new SleepyHead, but the data for those items still seems to be missing since I started on the nasal pillows.

Any thoughts about what's happening to the data? TIA.

Was the SD card in the CPAP overnight? Was the write-protect tab set to allow SD card writes? The PRS machines don't retain all the data otherwise.

It's what happens to me if I leave the SD card in my computer, or forget to set write-protect off after it's out of my computer.

I do turn write-protect on every time before putting it in my PC. It's supposedly not necessary - right now - in Windows 7 but all it takes is one "fix" to make W7 behave like W8 or iOS...

Would EncoreBasic shows any data if the SD card was not in the machine or incorrectly inserted

Thank you!
That seems to be the solution. Last night I remembered to take the SD card out of the PC and put it back in the CPAP and today I have all my data.
