The Philips Respironics CPAP machines have an SD card reader in the back. They use the card to store data for a "compliance download", which is required by some (many?) insurance companies — they want you to prove you're actually using the device, otherwise they won't pay for it.

Is it possible to read the data off of this card?

My specific device is the Philips Respironics 460P (RemStar Pro with C-Flex+)
