Any ideas what happened here?  This is for a period of just over an hour, beginning about 5 AM last night.

Any idea what was going on when all data ceased six times, after about 5 AM last night?  Please see OSCAR chart below.

First order of business should be to fix your mask leaks.

Yes, understood that's not desirable but they are usually much lower.  I've no idea why it's so variable.  The mask info for my profile is not current.  I use a ResMed N301 nasal cushion mask.  Meanwhile I still need to know what happened just after 5 AM this morning, and there was no mask leak issue at that time.

Several first steps.
1, clean the contacts on the SD card and the machine.

2, try a different or new SD card.

3, long shot. Unplug the machine for a while to effect a reboot of sorts.

4, if the issue persists. Then it’s time for a repair or replacement.

Thanks, I'll do that.

As the SD ports are small on most electronics. cleaning the card and reinserting a few times and recleaning the card may help clean the machine.
