I did manage to learn that it has an SD card spot - but no card in the spot. I've not figured out how to get the data of the unit using anything wirelessly - if that is even an option. Going to try to figure out what this OSCAR is all about, mentioned in other threads.....and see if I can get some night's data from it to send to you veterans.
SD cards were very popular with digital cameras for years; I found 5 lying around in a box that were no longer in service.
There are two major 'features' to be aware of with SD cards - physical size/format, and data capacity.
Physical size/Format: Original SD cards are about the physical size of a typical postage stamp; 'micro SD' cards are about a quarter of that size (there were 'mini SD' cards as well but they are almost extinct at this point). My ResMed Airsense 10 takes the original SD card. Adapters exist to allow the smaller 'micro SD' cards to be used where standard SD cards are required. This page shows both the original and Micro variants:
https://www.kingston.com/en/blog/person ... card-guide .
Data Capacity: older SD cards had limited capacity - 1 GB, 2 GB, 4 GB, etc. Current SD cards can have 512 GB, 1TB, etc - massive capacities. You don't need high capacity for the CPAP machine - even a 2 GB card will hold years of data. Technically, the different capacity cards can have different names (this is shown on the 'Kingston' page I linked to above) - "SD" = 2GB and under; "SDHC" = 2GB up to 32GB; "SDXC" = 32GB up to 2TB, and so on - but they are all generally referred to as 'SD Cards'. (they also have different 'speeds' and that gets into a whole other set of acronyms, like UHS-II, etc - but none of that matters for the CPAP machine).
This Wikipedia page does a good job of explaining the different types -

There's some chance that a modern, high-capacity card may not work with the CPAP machine because it's too 'big' (others will have to comment on what works); ResMed recommend a standard SD card with 2GB capacity. 2GB cards are getting harder and harder to find as the higher capacity cards become cheaper. Here's one that's guaranteed to work with a ResMed CPAP machine:

This is what I'm using in my ResMed device:
https://www.amazon.com/Sandisk-MicroSDH ... ef=sr_1_10
It's an 8 GB 'micro' card that slides into the 'standard SD Card' adapter so it fits inside the ResMed device.
Next - you need to READ the data on the SD Card.
My 2014-era laptop came with an SD card reader slot built in. But my 2022-era laptop came with a 'micro SD' card slot only - no SD card slot. So - that's why I am using a Micro-SD card with a 'Standard SD' card adapter:
Once you insert the card into your laptop, 'OSCAR' has an option to read the data from it without any fuss.
Let me know if you need more info.
PS - your device may have wireless communications, but in my case (ResMed Airsense 10) it only talks to ResMed and possibly my clinic. I signed up for a 'myAir.resmed.com' account, but all I get is highly summarized data; nowhere near as much as OSCAR gives you.
