How can my pressure change in the middle of the night ?
My pressure has been 8-11 for months. 1:30 this morning it changed to 18 which woke me, sort of. I tried sleeping without success until I gave up at 3. I could then see the pressure in Oscar sat at 18. I watched a film and could see it wasn't me. I went back and set it to 8-11 again and saw it seemed to hold.
Could it be a blip in the machine (resmed air sense 11) ? or someone/something external ?

RE: How can my pressure change in the middle of the night ?
I'm not talking about how the CPAP adjusts pressure within the range it's given. The range on my cpap changed in the middle of the night, from a range of 8-11 to a fixed 18.
Attaching the graphs anyway, so you can see abruptly it changed to a steady 18 at 1:30 am, even after stop/start a few times.
This morning I changed it back to a range of 8 to 11.
But my question is about how to tell what externally might have changed my settings, not that any should have.
I would guess it could be my sleep study dr (who 4 months ago said see you in 6 months), or the company
that I got the machine from, or My Air maybe.
RE: How can my pressure change in the middle of the night ?
Does your doctor and DME have your permission, direct or implied, to change your CPAP settings? Maybe you want to revoke this by an email, phone call, letter, all 3. "I revoke any implied or direct permission to change my CPAP settings over the air, or directly on the device." Something of this sort.

RE: How can my pressure change in the middle of the night ?
Appreciate the response. I suspect I gave implied access to Dr and DME and My Air, none of whom are pleasant to talk to. Maybe I'll take a look through my history and see if there were other cases of unexplainable high pressures.
The large leaks were all when the pressure was at 18. I have managed to go from a back sleeping snoring mouth breather to a largely side sleeping nose breather, never snoring. Most of the large leaks come when I roll over to face down or back to face up and start opening my mouth.
4 of 5 nights I stay under 25 95% of the time. Instead of religiously waking every hour and conceding after 3 or 4 hrs (for many years), I commonly now sleep in 2-3 hour chunks. I'm averaging 4.5 hrs of sleep on cpap machine probably another 2 hrs without cpap ( mostly from naps which I no longer fight). My largest improvement came from wearing my dentures at night (which showed my tongue where to go and stay). My energy level has skyrocketed the last few months, so I refuse to lose sleep over occasional large leaks.
I suspect my pressure is too high plus my mask used up (I've been changing about every 3 weeks). I will likely try both tonight.
Couldn't think what you meant by standard response, although I now suspect you mean the typical suggestion to go full face mask. To be honest, I'd try going no CPAP first.

Your machine settings are on the left panel. The fourth from the bottom is Response. You are set for Soft. Dave suggests that you change that to Standard. Most folks find that Standard works better.

Yes, Standard Response is within your CPAP, and not related at all to any mask suggestions. It's a setting you can access yourself, it might be within the clinical menu where pressures are set. Easy access either way though.
You can see it listed on OSCAR, left panel under device settings about 3/4 down.

In OSCAR under the tab 'Statistics', scroll down to 'Changes in Device Settings' and see if the machine actually registered a setting change. Is the prescribed pressure from the Doctor/sleep study different than what you have it set at?
RE: How can my pressure change in the middle of the night ?
So I changed to STD response and also lowered my pressure to 7-10 and put in a new mask.
The night was choppy but persisting till the light of day was great and unusual ! As always, if
changes don't go south, I try to give them a week to better understand the impact. Good way to end the month !
