ResMed Airsense 10 malfunction?

I've been on CPAP for a bit more than a year and I was woken up this morning to sudden, sustained high pressure from my CPAP and difficulty breathing. It seems like maybe it's thinking I'm having a blockage although I am not. I tried power cycling, checked all my settings, but as you can see from the Sleepyhead data, after the initial few minutes, the machine goes back to high pressure. Anyone know what's going on and how to fix it? Thank you.



Zoomed in:

I take it you were awake totally from the 4:55 to 5:35 mark where you gave up and got up?

What is your ramp setting and how long? Is it on Auto or regular ramp?
If ramp is on..turn it off totally.

Go into the clinical menu and verify that the minimum pressure hasn't been changed by aliens.

Play with the machine today while awake like you did from 5 AM mark on...see if it keeps acting up.
I don't know what's wrong or how to fix it but if it still keeps acting up my first suspect would be a faulty sensor and requires a visit to the DME (and of course they are likely closed today)....do you have a back up machine available?

Sorry for my delayed follow-up.

Yes, I was awake during that time. No, no settings have been changed. No, I don't have a backup. Ramp was on Auto, as it has been for as long as I've had the CPAP.

I took the outer casing off to see if there were any obvious issues and found that the hose port was not fully seated. I'm not sure if that was causing a problem - and, if it was, why all of a sudden at 5 in the morning - but I reattached it properly. I reassembled and it's been working correctly for the past 2 nights.
