Strange Graph in Sleephead and other questions

[HGMonaro]

Hi, I'm on the 1st week of my CPAP trial and have discovered Sleepyhead before going back to see the technician tomorrow. I think my clock is an hour out but pretty sure I got up, put the nasal pillow on side table and left my wife to have a sleep in. Why all the events after 7:09am (as per graph). The machine is a Phillips System One 60 Series. The other mornings I've remembered to turn the power off so my data/graphs end pretty much after I woke up. This graph seemed to run for another 2.5 hrs before the machine decided I'd left the room!

(if the graph doesn't show, something went wrong.. but basically the flow rate stops but there are still events shown for the rest of the graph)

Another thing I can't understand is why Sleephead won't load my last nights data in. On the SD card there are 6 data files (I'm basing this on the size of the files) but it's only loaded 5 and is missing the one from last night.

Thanks in advance for any of your thoughts, I'll check back in the morning before heading off to have my appointment with the techy guy.

Since no one else has jumped in, I'll throw out a wild guess. To me, it looks like your some of the flag times got offset by about 2 to 3 hours, and the sleep time extended by that, as well. I have no idea how that could happen except through a machine error, either writing the data by the CPAP machine, or reading it on the computer.
My only suggestion is to delete the day's data and re-import it. First select the day in the 'Daily' tab, then go to the 'Data' menu, drop down to 'Advanced', and select 'Purge Current Selected Day'. Then go back to the welcome page and re-import your data.
Beyond that, I don't know what to suggest.

Thanks for the suggestion. I reloaded the day but still shows the same graph, so most likely CPAP machine related. Will be interesting to see if the technician says anything about it.
