Missing Data Respironics Card Reader (encore)

Hi-- I have a fully data capable Respironics bipap and have been successfully viewing data using the data card and reader. I was really starting to feel better and so didn't bother looking at the data for probably over a 4-6 weeks. Then "poof" I started to feel tired again, needing an afternoon nap again etc.

When I went to review the data using the card and card reader, I was able to retrieve the daily data for the last week, but found that only summary data was available for previous periods. It would give me a weekly summary for the week I selected but not any of the dailies...so that a report would end up being around 5 pages instead of 12.

Does anyone know why this daily data would disappear from the card reader? I am not talking about the LCD display, I understand how that rolls over, but instead the card and card reader.

Thanks much,

Jan

I am sure that someone with more knowledge will post on this. I believe that the machine will only save the data for so long.

I thought that the data was actually stored on the card, and not the machine. It sure would be helpful to have that data in order to track back the patterns to see if I can figure out what triggered this regression in how I feel.
