Resmed Airsense 10 SD card

TL;dr How to write internal therapy data to an SD card?

Hi all from your latest total noob. I've been lurking for a bit and am refreshed by the Adult attitude of you knowlegable, patient participants.
My DME delivered my CPAP without a SD card, so it logged all my data to internal flash.
I would like to write these records to a formatted SD card so I can use Oscar (and prove compliance), but I see that merely inserting the card and power cycling the CPAP did not transfer those records to SD. Resmed's User Manual was helpless. I scrolled through the User and Clinician menus and did not see a 'Write SD card' entry. How does one do this please?

Thank you!

Exactly what model AirSense 10 machine are you using?

Normally just inserting a SD card into the machine is all that is needed for the machine to write everything it has stored in its internal memory to the card.

Why do you think it didn't do that?

Wow! Thanks for getting back to me so quickly, Pugsy!

I thought so too.

> Why do you think it didn't do that?
I inserted my formatted SD card, powered up and poked around in the menu structure for a while then powered down. I expected to see a prompt on the screen like 'Writing Records, do not eject card' or something. But I saw nothing of the kind. I ejected the SD card.
I placed the card back in my PC card reader and the PC said it was still blank.

Make sure the SD card isn't write protected first.
Then insert it into the machine and watch the screen for any prompts you may or may not see.
Report back what you see or don't see. It will take a few minutes so don't get in a rush. The machine should acknowledge the card...if it doesn't maybe it isn't pushed in far enough.

There is no clinical setting menu that you can use to prompt the machine to write to the SD card. It's just not there. It's automatic and if it isn't writing to the SD card then there is either something wrong with the SD card or perhaps the internal software within the machine telling it to write to the SD card.

Finally...did you actually try downloading from the SD card into the OSCAR software?
What makes you think the PC said it was blank? Did you actually navigate to the SD card and look inside the SD card? If it was indeed blank....something is wrong with the machine because there would be some text files if nothing else.

So....possible drive failure if you can't see inside the SD card.
possible writing to the SD card failure
possible SD card being write protected

Something isn't working like it should but more trouble shooting is needed to narrow down the culprit.

> Make sure the SD card isn't write protected first.
Yup. Confirmed that and was reassured when my PC formatted it with no errors.

> Then insert it into the machine and watch the screen for any prompts you may or may not see.

Normal boot up process. 'Resmed' splash screen just like always. No reference to an SD card.

> The machine should acknowledge the card...if it doesn't maybe it isn't pushed in far enough.
Hm. I will try it a few more times. The SD socket on the CPAP acts perfectly normal. My PC card reader has no problem reading or writing the card.

Ah. So scrambled firmware in the CPAP, eh? That's probably the problem.

> Finally...did you actually try downloading from the SD card into the OSCAR software?

Not yet. I did not see any SD files at all on my PC, unlike with my other CPAP SD card which shows that the CPAP wrote data files. Seemed like a pointless thing to do, (since the PC sees the proper files from my other CPAP SD card and Oscar works fine with my other CPAP SD as well.)

> What makes you think the PC said it was blank? Did you actually navigate to the SD card and look

Yup. That's how I did it.

That would not surprise me. My DME is a sociopath who could not resist scrambling my settings after I came out of 'Airplane' mode. Who knows what else he did?

> So....possible drive failure if you can't see inside the SD card.
I see just fine inside the card. It is blank. Has a FAT32 structure but no files.

> possible writing to the SD card failure
I concur, Doctor.

> possible SD card being write protected
Beg to differ. Tab is in 'unlock' mode and it formatted just fine.

OK Thanks, Pugsy. Personally I think my DME screwed up the CPAP firmware. His end game is to 'prove' non-compliance as a cost - cutting measure. I can't prove compliance without the records and he's not going to accept screen pictures to show I'm using the machine in good faith, (While it is working.)

I appreciate your help.

I don't know of any way any DME could mess with the machine internal software so that it won't write to the SD card.
BUT>>>>> he very well could have given you a machine that is/was already known to have a problem writing to the SD card

When the SD card is inserted into the machine even before it is ever used there is a little text file written that contains the machine model and serial number and it is easily seen if you navigate to the SD card and look inside. In fact I think there might be 2 text files....I would have to go look at my machine to confirm but I know for a fact that the machine should write at least the serial number to the SD card....if there is no such file on your SD card....the machine simply isn't writing to the SD card.

I have heard of machines having a failure of the internal software being able to write to the SD card. It's rare but not impossible.
And it has absolutely nothing to airplane mode being on or not. The SD card is independent of the airplane mode feature and the writing to the SD card is independent of the airplane mode feature being on or off.

Sounds like you have a defective machine.....at least when it comes to writing to the SD card or maybe even its own internal memory storage....and that would really piss me off because then I would wonder what else might be wrong with the machine that I wouldn't have any way to monitor or know about.

On your computer format the SD card to either NTFS or ex-fat, something other than FAT32.

Now, put your SD Card into the AirSense. It *should* detect an SD card has been inserted with a foreign filesystem and format it as FAT32. After laying down the filesystem it should create a data structure including:

STR.edf, identification.txt, DATALOG

If it doesn't, there is something wrong with the SD Card or the SD Card reader on the device. Make sure there is no water in humidifier if your lifting machine and looking around in SD card slot.

Look inside the reader to ensure there's nothing blocking any of the sensors, or try a different SD Card. Any modern SD Card (SDHC Class 10) will do.

This is not reasonable.

Disabling the ability to write to the SD Card is not a supported feature, and it is *extremely* unlikely that anyone at your DME can patch the firmware and re-flash it solely to disable the ability to write to the SD Card.

And to what end, you can now demonstrate the device has a problem and are entitled to a replacement or fixed.

You don't have to prove compliance. They have to demonstrate non-compliance. Typically they can with the data upload or an SD Card showing non-compliance.

Call the DME, tell them the SD Card reader doesn't work, and get a new machine.

The CPAP is just a computer with peripherals, yes?

I'd just gotten the machine back from Apria yesterday morning to address the classic Resmed 'leaky humidifier' tank problem. You'd think they would do a functional check on everything before releasing it back to me, no? No.

I concur, Doctor.

Indeed.

Agreed.

The sociopath gatekeeper at the hospital knows that if he can discourage people from using DME, his numbers look better. If it causes suffering, then that is another bonus for him. He is not a very nice man.

Excellent, Doggy! I reformatted the SD card to NTFS and after booting up the CPAP, I got acknowlegment of card insertion and two SD card folders, DATALOG and SETTINGS, as well as three files, Identification.crc, Identification.tgt and STR.edf on the card that did not work before! This is more like it!
In addition, for the first time, Oscar did a nice clean import of my Resmed data from that card.

You are a God. Thank you.

Good for future reference. Thanks!

Sorry, I meant the evil gatekeeper at the hospital. The DME vendor appears innocent. The evil gatekeeper at the hospital will do or say anything to prevent me from using this machine, while still 'appearing' as if he is doing his job. A real piece of work, that one.

You fixed it. Thanks again!

A lot of new cpaps have like a modem or something like where the Dme or sleep doctor can download information if they need to see it.

That does not work so good if the gatekeeper to your sleep doctor is a sociopath. My gatekeeper used wireless access to make my machine unusable. It was broken for several days.

I recently got a new Resmed Airsense. It didn't come with a SD Card, but it does connect to a cellular phone network. I don't know which network it uses. It shows only 1 bar but that seems to be enough. Using a cell network instead of wifi is simpler, but if you don't have cell service where you are, you have to move it to somewhere where there is... or use the SD Card.

Having used OSCAR to look at the data for my old DreamStation, and being a data nerd, I wanted to add a SD Card so I could look at all the details.

Following the info above, I got a 32 GB SDHC UHS-1 SD card.

As noted above, it came formatted as a FAT32 system and it needs to be changed.

• Insert the SD Card into your PC, then in explorer, right click on the card icon (labeled SDHC for me)
  -- you will see File System = FAT32).

• Reformat the SD card so that it is something other that FAT 32. This is done so that the Airsense will reformat it in the way that it needs to as well as initialize the file system.
  
  • In explorer, left click on the SD card icon
  • look at the top of the window and click on "Manage", and then "Format".
  • In the format dialog, change "file system" from FAT32 to NTFS. Click start , etc.)

• Remove the SD card from the computer.

I unplugged the Resmed Airsence, inserted the SD card, and then plugged it back in.

I then used the dial to select "Sleep Report" and the "MyAir". It showed a message that it had detected the card and formatted it.

I let it be for a few hours and then removed the SD card from the Airsense (unplugged it first), and then plugged it into my PC.

It had 2 folders (DATALOG and SETTINGS), as well as 3 files in top level folder. So looks good there.

OSCAR was able to read the data ... I see the Overview results, but no Daily data. Bummer. I'll check tomorrow. It probably writes the data there before sending it up.

Hi mihondect
Thanks for all that. That formatting process made all the difference for me. I have since put away my Airsense 10 and purchased a Philips Dreamstation. It Just Works! It’s expensive but worth every penny. IMHO.

After a couple of days, I looked at the data on the SD card again (using OSCAR). All the detail data is now there since I put the SD card in.

I was using a Dreamstation with mixed results. So far (for me) the Resmed is doing a better job (AHI consistently lower). Resmed seems quieter.

Please consider placing a drip pan under that Resmed if you are using it’s humidifier.
Mine leaked on my new hardwood floor which has swelled and buckled.
