Switching SD Card From Primary to Travel Machine

[2 B Sleeping Soundly]

Has anyone here had experience switching your SD card from your primary machine to your travel/back-up machine? I am going on a over night trip and wanted to take my SD Card from my primary PR System One to my travel/back-up PR System One. What I am worried about is possible data corruption and also showing my history of continued compliance for the RT/Doctor should they ever want to see the information on it.

Thanks!

Sd cards are really inexpensive these days. Why not just get another? Just sayin'

If you are still under compliance reporting, I wouldn't use any other machine than the one that you are recording compliance for. It's useless to record compliance data on a backup machine, as it does not count. I would just use my primary machine on the overnight trip and not bother with other machine until you are finished with your compliance reporting.

Also, if you put the sd card into the backup machine, it will want to erase the card anyway. Your compliance data from the primary machine would get rewritten to the card when you put it back in that machine, but why bother?

As Vader says above, get a different card for backup machine if you want to have your sleep data, but for compliance it's a non-issue.

Agreed, the backup machine will format the card, especially if the machines aren't identical.

However, you can import data from multiple cards into most of the software tools to view your data, so that's not a problem. As was already mentioned, even if the data isn't wiped, the doc will probably just consider the different day an anomaly and skip it =)

I don't think the PR S1 machines will erase the SD card if used between 2 different machines.
I cannot swear to it though. They aren't near as finicky as ResMed machines. I have sent an email to someone who I know had one SD card and used 2 different machines and asked her what happened with her reports. When I hear back I will post.

Just to be safe though...one could copy the entire contents of the SD card to a folder on the computer.
Should there be a problem it would be easy to erase the SD card and replace the files with the copied contents saved.

Compliance requirements won't be messed up by missing a night or 2 of hours when the rest of the time it has been perfect. A few missing hours won't make or break things after this long of being on the machine.
Though I can understand the desire to have everything on one SD card and one report. It's a mental thing.
SleepyHead won't care..that I know for a fact.

I no longer have an extra PR S1 machine to test what happens when 2 machines are used with one card.

You know it would be easy to check to see what would happen if you used 1 SD card and 2 machines.
Would need to do it now though.
Make a copy of the entire SD card contents and place it in a folder on the desktop for safe keeping.
Then go fire up the travel machine and use it with the SD card for about 5 minutes.
Then go open SleepyHead....create a new user profile for testing purposes...import the data and see if the old data is there along with the 5 minute new data. If the old data is there...the travel machine didn't mess with the old data on the SD card. If the old data is gone, you have your answer and to fix it...just erase the SD card and put the contents that you saved to your desktop back on the SD card.
Then you would know you need a second SD card.

Thanks!

I hope you are kidding. If not, what has the doctor-patient relationship come to?

If my doc complained I would tell him to k

I have used the same card across three different PRS1s with no loss of data. Each PRS1 simply stores to a different folder.

As far as I know, all machine brands format as FAT 16...I will test and see if mine reformats in the IntelliPAP as well. Currently I'm using separate cards for the DeVilbiss and the PRS1...I'd be interested to see if the DeVilbiss or the PRS1 attempts to reformat the cards from the other machines.

Thank you. This is what I needed to know. I thought this would be the case. I just didn't have any way to test it. For an extra layer of precaution a person could go ahead and save the SD contents to the desktop if they wished. SleepyHead will combine all the machines.. I am unsure what Encore might do though.
I know when I tried to combine M series data with PR S1 data...the M series data lost and got erased.

Don't know about different models, but I trialed a PRS1 apap and I just pulled my card out of the PRS1 cpap and put it in (didn't know any different!!) I did however, make a new "patient file" on the Encore and labeled it trial Apap, then downloaded my new data into it...I didn't download Sleepyhead til this last beta version and it brought up all the data on the card..included both machines and their data for those nights! Hope that helps!

Thanks to everyone for your thoughts about this. I think what I will do for this over night is use a different SD card (as was suggested) and set up a separate profile in SleepyHead (I don't use Encore) for the travel machine and it's SD card. When I take my next trip in a few months (this one will be over a week), I will do the experiment others posted about, using the primary machines SD card in the back-up machine, and see what happens then.

I know my concerns about compliance are really silly and it is just me being a over-achieving hose head ('Look at me, I haven't missed a day...Woopie'). I think I met my compliance (it might have been a 30 day ) a while ago on 12/09/11, but even if I am wrong and was a 90 day compliance, I will have 98 days after tonight. No worries...
