Help with Airsense 10 Autoset settings - lavamanz - 10-11-2015
So first the doctor prescribed the ResMed Airsense 10 Elite with a setting of 11. I was able to get him to prescribe the Airsense 10 Autoset & he gave settings of 8-13. I have used machine about 10 days & downloaded data to ResScan. I notice pressures were bumping up to the max of 13 after about 4 nights. I have now adjusted max to 14 for several nights & the pressures got close to 14, then I adjusted max again to 15. Last night on the essentials plus it indicated 14.8 so I am now getting up to the max again. Should I bump it again? It seems odd since I did a sleep study & 11 fixed was what was prescribed.

I would say that the pressure indication means little without you telling us what the accompanying AHI score is on the varying pressures that you've adjusted on. Is the AHI score still high?
There could be many reasons why the pressure continues to bump up to the top - some which may be unrelated to you not getting less than adequate treatment.
What was your original titration? There's got to be a reason why he prescribed a pressure of 11.
EDIT: I think you probably are adjusting your pressures too quickly - I started at 8 to 20, and at first, my pressure was hitting 20, but over the past two months of treatment, it's lowered to under 18 for most nights now. Perhaps you should hold off on making the changes so quickly.

Welcome to the forum lavamanz,
Pressure can rise for different reasons. The machine can respond to snoring, and flow limitations, etc.
Without data to look at, you may be making your situation worse by raising the max pressure without having a reason to do so.
Download Sleepyhead software (link at top of page), and start looking at your numbers before making changes. The graphs will tell you what is happening at any given time.
Also, you haven't said what your AHI readings have been.

To expand on what ramblingasian said, you will need time to adjust to the machine let alone the pressure settings. Run with what you have now for awhile. I would say for at least two weeks. I also have seen a decrease in my Max pressure. I had 15 as a max pressure and I rarely hit 14 now. The autoset will only go that high if it needs to so the max settings isn't as crucial unless you start getting pressure-induced events.

If your AHI readings are so low as you state above originally, there is absolutely no reason at all why you needed to increase your pressure at all to begin with as your results indicate that your treatment is working properly as previously prescribed.
In fact, you're probably better off not touching the settings.
The only reason why you should have increased the top end is if your AHI were still high (above 5), but your scores do not indicate that at all.
RE: Help with Airsense 10 Autoset settings - OpalRose - 10-11-2015
lavamanz,
Yes, your AHI readings are within the "treated" range of <5, but the question is: How do you feel?
Some folk feel great with those numbers, and some don't. Everyone is different.
Your original question is why your pressure rises when you changed your max setting, and I can only repeat what I stated above. Download software and start to track your therapy, then you will start to understand why pressure rises and falls during the night.
Your pressure could rise for many reasons, sometimes just turning over in bed and holding your breath for a short time.
Also, when you do make a pressure change, you should leave it alone for a week to 10 days minimum.
Added note: Look to see what your 90% pressure reading is. This gives us a better idea as to where your starting/minimum pressure should be.
Just an example: if your 90% pressure reading says it was at 10, this means that your pressure was at 10 or under for 90% of the night.

I set the maximum at 13 and the machine can only go to 13, seem to me a good compromise .... YMMV. Ask your doctor
How is the leak rate and any dry mouth or stuffy nose?

Leak rate (95th percentile) varies from 4.8L/min to 15.6L/min. No dry mouth or runny nose, I do not use the humidifier
