Getting a prior CPAP-er back in the wagon

Ok, so my bf used my machine so we could look at his results since he hasn’t had a study in a while. Is there a way in Oscar to keep multiple “profiles”. Of bf set up his own account, is there a way to only load the sessions where he was using the machine under his log in? And conversely, is there a way I can keep his data from winking up my data. Can I just delete that particular session from my Oscar data folder?

You can purge specific dates from the user's OSCAR profile.

Look under the Data tab and click on "advanced".

So you can remove his night from your profile if you wish and his profile you can do the same to all your prior data.

So you can have multiple profiles within OSCAR and remove specific dates from those profiles.
