according to the manual, the min pressure on the autoset can be set from 4-max pressure, and max can be from min-20.

did you perhaps have max set to 12?

So here is the data after one night. Also I checked my machine and it appears that 12 is the highest minimum pressure that I can dial up to. So if I raise the pressure it will have to be 12/13 unless there is a setting that will disable the min max options somewhere I didn't notice.
I really appreciate both sets of input so please feel free to keep commenting. I don't think its a matter of right or wrong perhaps different things work for different people such as myself that sleeps on my back too much !!

Along with PR's comment, which pressure did you try to change first?
You would have to change the maximum pressure before you try to move the minimum pressure to equal it.

The PR S1 machines won't let you increase a minimum until you increase the maximum first when the maximum is equal to the minimum.

I learned that the hard way...with my bilevel auto...spent half a day cussing the new zero hour machine that wouldn't let me set my EPAP higher...it couldn't because the IPAP was lower because I hadn't given PS some room to work..

Change your maximum first and it will allow you to change the minimum so you can continue the 13/13 if that is what you wish to do.

OP seems to have an autoset (it's so seldom I get to catch Pugsy out on something!)

Damn...that you did...but to be fair...I never said that OP had the PR S1...I only mentioned what one had to do to make that desired change with a PR S1...and that I had that same issue with my PR S1 and my last comment was just..
Change the maximum first and you will be able to change the minimum. I didn't say...change your PR S1 max first....it was generic "change max first".

And that's my story and I am sticking to it. I know you believe every word of it.

At least I left out the brand in my post.......immediately before hers. I think the principle is the same with either one.

I believe most near ever'thing you tells me!!! you know I do!

might be a bit tough for the machine to manage a minimum of 14 and a maximum of 12!

Last night I changed the EPR back to 3 and then changed the pressure to 12/13. I now found the setting that allows me to make the machine a straight cpap instead of the auto set so I may change it to that setting tonight and try 13/13 if you think that is ok.

Sounds like a plan to me.

Here is two nights of the data with 13 in cap mode. Still not much improvement. I am trying to sleep more on my side but i keep moving to m back after I go to sleep I think. Not much difference here as I see it. The big leak on the last one was when I got up to go to the bathroom. Any more suggestions to clean it up some more?

I think a couple of options are......Trying to stay on your sides (using a wedge pillow, back pack or tennis balls in a T-shirt) or keep increasing pressures (or maybe both).
Actually, the pressures you've been at are not all that high for straight pressure........yet. Over 16 or 17 would be starting to get into "high" territory.

I also find the "spacing" of your apneas intriguing. With a few exceptions, there's almost a pattern to them. Don't know if that's a clue or not.
If you're seeing the reports for "Flow Limitations", are you seeing many/any in them? They're a potential apnea precursor on which the APAPs trigger pressure increases. If there are few or none of them, there's not much use in using a range of pressures to head off the apneas. Looking at the "summary stats", I don't see much in the way of numbers for them. Same with Snores. So, I don't see any sense in using a range of pressures in that regard.

Flow limitation reporting on the S9 isn't offered in a "number of flow limitations" like Respironics machines.
Instead it is offered in a graph that measures the breath itself and not the number of times it happens...harder to evaluate but in general the more stuff you see the worse it is and the idea is to have minimal anything on the flow limitation graph.

Could you please add a picture of your flow limitation graph for last night?
Statistics are showing maximum of 0.96 and the highest it will go is 1.0 but the 95% number is only 0.26 which isn't horribly high. It's really hard to evaluate just by a number...need to see that Flow limitation graph.

Thanks Pugsy.

My thoughts exactly.
