KC2684 - ResMed AirSense 10 AutoSet Therapy Questions

[KC2684]

I've been using the Resmed Airsense 10 AutoSet (for Her) for a couple years.
I recently started reviewing my sleep charts using OSCAR (which I love).
I operate it in APAP mode with a min pressure of 4 and a max of 11 cm H20. Ramp is off. 
What I notice is that the pressure starts to ramp up without any apneas being recorded.

Question #1 
Can anyone tell me what what initiates this increase in pressure?


Although my proscribed pressure is 13 cm H2O I get very severe dry mouth. As I reduce this pressure to about say 8 cm H20 over several days, the dry mouth does not occur.  I keep the humidifier on the max setting and there is water left in the morning. This even seems to be the case when I keep my mouth closed, or think I do.
Question #2
Is this a common problem with higher pressures? 

Thanks
Barry

The Resmed uses the flow limit as the determinant in setting the pressure. As the flow limit increases, so will the pressure.

Please update your profile to reflect your new CPAP, pressures, and mask. It can help in forming a response to your questions.

Thanks. I was unaware of that. I have included a screen grab including the Flow Limit.
I'm working on updating my profile.

I just realized that your initial post was in the CPAP review forum.  Since your posts relate to questions and not making a review, I have split them out into their own thread.  I have renamed your thread, KC2684 - ResMed AirSense 10 AutoSet Therapy Questions.  This title will allow you to post a wide variety of questions and/or insights concerning your equipment and therapy.  Please use this thread for all further posts on this subject.

I am following this post up with the same message in a PM.

Two things that I see that may help future responses to your post.  1. Please use the F12 key or (Fn+F12 if on a Mac) to take the screenshot of the daily screen.  The data on the left provides a bunch of information.  2. Change back to the Standard view for your graphs.  The "Advanced" view is intended for advanced CPAPs, such as an ASV, ST, ST-A, or iVAPS, and does not provide any additional information for your CPAP.   The wording for these views has been changed for upcoming releases to correct this misconception.
