Hi
luke1081,
You don't say which area you're in, or which foundation trust hospital your sleep-medicine department is part of. In many FTHs, you only see the consultant once – ie, after the home sleep-study, and to make you formally and legally a patient of the hospital.
After that, your treatment is delivered by the specialist nurses and sleep physiologists in the sleep-medicine department. The way my treatment is, here in Gloucestershire.
That much is for background – because I'm trying to figure out why the consulant forbade you taking the SD card out.
It is true that if you take the card out – say, to read on your laptop or computer – and don't put it back for a day (technically, across midday) or two, then that will show up the next time the card is read by the staff at the sleep-medicine department. At your review, for example.
And even if you did take out and put back the card in the same day, with the ResMed machines, if you don't move the little 'slide' thing on the side of the card to the 'write protect' position
before inserting it into your laptop or computer, there maybe a glitch when you put the SD card back into the ResMed machine (with the 'write' tab moved to 'permit' again).
And rather than explain all that, the consultant may just be telling patients not to.
There is shareware/ software called Sleepyhead which lets you read your SD card in some detail. I can't think of any reason why you should not know how your treatment is going. And I can think of several reasons why having such information helps you get the best treatment.
