Philips Respironics Bipap Auto SV, cards and settings

[SenatorBirch]

Not my machine, so forgive my ignorance!

Using Philips Respironics Bipap Auto SV Advanced System 1

I gave my SD card (Card A) to my provider so they could change the settings, which they did. I have it back, but have not put it back in the machine yet. The machine currently has no card in it at all.

I want to be able to revert back immediately to my current settings if the new settings don't work well. (This is a MUST; long story, complicated, other serious health issues etc)

It's my understanding that if you insert an appropriately formatted SD card, with settings, into the machine, then the settings get copied from the card to the machine. (That's how I'm getting the new settings from the provider to the machine, so it must work that way.)

I have another SD card (Card B). I want to use that card to store my current settings. So my question is, how do I get the current machine settings to transfer over to Card B?  (Remember, there's NO card in the machine right now)

Incidentally, Card B appears to have been used in the machine some time ago, but I have no idea what's on it. I would prefer to just wipe it clean to be safe. I want to be confident that Card B gets the current machine settings, and that subsequently, if the new settings (on Card A) are not appropriate, then I can get my current settings back by inserting Card B.
How do I format Card B? Just use a Windows PC?

Thanks in advance

It is a special file that the CPAP will see when it is inserted. This file will remain on the SD card, and even if you change the settings back, it will read the ones in the file and set the CPAP back to them. If you have another card that has the current files from this CPAP, compare all the file names of both cards and find the one that only appears on the DME modified one. That should be the setting file.

Thanks for the answer.  However, I don't have a card with the current settings. In hindsight, I should have gotten the DME, before changing the settings on Card A, to copy the current settings to Card B. I think I've gotten them to do that in the past, but didn't think to do it this time.

So if I understand you correctly, there's no way to insert a "blank" SD card and have the machine transfer its settings to the card. It's always going to be a one-way transfer (machine to card) ?

If that's the case, I'll have to look at other options. The DME probably has a record of the old settings; if not, I can bring the machine in for them to get them. Either way, it's not the end of the world, but I had hoped for a DYI solution because (a) I could do it tonight, and (b) the DME recently started charging for each visit

Before you insert the new card, stick a blank SD card in your CPAP. This will create all the necessary files. You can then compare the two.
