lending machine and keeping data separate

I have lent my machine on a few occasions to family and friends. What is the best way to keep their data separate from mine? Can the machine have more than one user assigned to it?

I literally just now came to post this exact question, now that the forum is safe for use again. My undiagnosed but symptomatic wife wants to do a two-hour test on the machine on auto settings to see what the Sleepyhead data says. I want to let her use my VAUTO but don't want to "contaminate" my data set. How can we keep them separate? Use a different SD card and Sleepyhead profile?

What I have done when I have loaned my machines out is erase the prior data from the machine (I have it in the software anyway) and make a copy of the SD card contents and set it aside for safe keeping...and then erase the SD card so that it goes to the new person totally clean.
It just makes evaluating the data easier.
When the machine comes home it gets erased again and the SD card gets erased again.
In SleepyHead I just use a new user profile for whomever has the machine.

But you can leave all the data on the machine and card and just make a mental note when the machine went out on loan.
Overall long term averages get skewed but if only evaluating each detailed night then it really doesn't matter what the long term stuff looks like.

There's no way to separate user data on the machine itself that I am aware of. I don't know what you mean about "assigning" though.

There's no way to separate the data on the machine itself...you could use a different SD card and profile but the machine doesn't let you separate one night from another and if all the nights are on the machine they will all go back onto the SD card even if it is blank to start with.

I have done what you want to do...I had to erase both the machine and the SD card.

If you still have potential compliance hours of use requirements in the picture obviously you don't want to erase your old data...about the only thing you can do is just let her data get mixed with yours and use a separate SH profile (but it's going to have your old stuff in there too).

In all honesty...2 hours or even one night is really going to make that much difference long term so if you think someone might want to look at your old data from the machine...I wouldn't worry about a little contamination.

Now if no one is ever going to be looking at your machine or SD card data...just erase it.

Thanks, and you're right. Statistically it won't matter at all. She's going to nap in the afternoon, so there will be a great interval between her data and mine.

That will work. Thanks
I was hoping that using a separate SD card would keep the data separate but it does not.

A few times now I've had an issue with my data – Sleepyhead told me one night's AHI was 29 million and change, another it was 67 million+. Talk about skewing your averages!! But I finally realized that Sleepyhead lets you delete individual nights' data. In the menu: Data/Advanced/Purge Current Selected Day. That would help OP's data averages to not be skewed by wife's test data, without having to purge the SD card.

Yep you can do that or a person could simply turn the short session off if that's all that is on it and not lose the other person's data.

Like if there is only a 2 hour nap in the afternoon and hubby uses the machine that night...we don't want his data to leave...so we can just turn off the nap session and that data is removed but his data would remain intact.

I got my machine in 2012. My mom had been on cpap for about 20 years and admitted that she never felt like it helped all that much.

So, after my followup with my doctor, I let my mom use my full data machine for 2 partial nights. I am a severe night owl, so I was still able to use my machine for my full night. We did the first partial night at her prescription setting of 10. After she slept 4 hours, she let me know she was done and switched back to her machine. I uploaded the data and printed the results before i changed my settings back and went to bed.

A few nights later, we did another partial night set at 10-13 to see what the machine wanted to do, without letting it go too high. Again, I printed the
report before going to bed and adding my own data. We then made an appointment for her with my sleep doctor. He reviewer he last sleep study and the two printed reports that I brought in. He prescribed a new full data machine like mine, set at 10-15. My mom is much happier and feels a lot better.

Yay Zoocrew!! So nice when things like that work out.

And now I have a backup up machine, so if somebody is willing, I can help them do a test night or two.

My sleep doctor was really cool. He prescribes full data machines because he knows the need to check the actual data. He has sleep apnea himself. I was so glad that he was willing to look at the printouts from my mom's partial nights to see that she needed better settings than what she had previously. Her old machine had no data. And her ahi would be misleading anyway. It was 3.4, but she had a cluster of longer events. She had previously tried to get a new sleep study, but medicare wouldn't approve it.

We just wait until my followup so that her added data wouldn't affect my data. After that, it was never checked again by the doctor, and it was so short that it really didn't affect my data.
