PAP->SD->OSCAR->Forum data management
After the night of the 10th, I noticed missing data in the bottom half of the OSCAR report (see images). This was puzzling:
I assume the PAP machine (a Philips Respironics DreamStation) collects data in an internal buffer and periodically writes it to the SD card. When I "Click to Close" in the morning, any partial buffer is flushed. Now and then I don't see the "Click to Close" prompt; what happens then? Is there a special "end of session" mark to indicate the end of a sleep session? When I first got the machine, the "Click to Close" prompt was fleeting at best, but now it generally behaves, and pops up in the morning after I turn it off and gives me a few seconds to click.
Whatever happens there, OSCAR eventually reads the SD card data, and accumulates it in its own database. Does it read the entire SD card to see what it's missing, or just start reading near the end, assuming it's got everything prior? How does OSCAR determine "end of data"?
Obviously, I'm wondering if, on the 10th, I missed a "Click to Close", data for the 10th was truncated, put on the SD card later when I inserted it after OSCARing it, and never fetched by OSCAR on later days. Do these data from the 10th show up in the OSCAR database anywhere? Doesn't look like it.
If so, OSCAR will never "fill in" any missing or incorrect data in its database?
As for OSCAR itself....
Awesome product. But:
1) Would really like to be able dump the entire output, rather than just the current screen, with an F12-like keystroke.
2) Would like to be able to add a short comment to an OSCAR screen. For example, while I was testing a bunch of masks recently, it would have been very useful to have been able to annotate the name of the mask used that night. Now that I've settled on a mask (I think) I'll change my profile, but for the last month or so, the mask type came from my then-profile (?), and was wrong.
Finally, as for the machine itself:
It was charged to Medicare as a "used" machine. But both Therapy hours and Blower hours are identical and more-or-less consistent with the total time I've had the machine.

. I did think of one more thing last night - when saving via F12 it would be nice if (how many time have you heard THAT?) the filename contained the date of the CPAP session (start, end, or both), rather than the date of the screenshot.
Sorry!
