How does OSCAR know my AHI when the CF card was locked?

[greyham]

Hi everyone,

I normally import my Resmed Airsense 10 Autoset CPAP data into OSCAR once a month, but I appear to have screwed up last month and put the CF card back in the machine without unlocking it. As a result, there are no folders for the first 2 weeks of January in the DATALOG folder, and no data for those days appears in OSCAR; except for the AHI on the overview window.

So two questions:
1. Does anyone know how much data the machine sends to Resmed? Could the full session data for the missing nights be recoverable by my provider?
2. How on earth does OSCAR know what my AHI was for dates where there is no folder on the CF card?

Thanks,
Graham

1. Resmed only sends the minimal data, no high resolution data is transmitted. That is why you need an SD card.
   
2. There is some internal memory that will hold about 30 days worth of Summary data. That data will be written to an SD card when it is inserted.
