Stu, to get the conversation back on track: You have some Flow Limitations remaining after treatment using your S9 auto with a max pressure of 20 cmH2O, the maximum of the machine.

The residual Flow Limitations appear to be "moderate" or less based on the examples you've given. Could these Flow Limitations be disturbing to you? Yes. Are they? We don't know.

To treat these residual limitations, you need a machine capable of providing a pressure greater than 20cmH2O.*See the Edit below That implies a bi-level such as the Aircurve 10 VAuto. Would treatment allow you to feel more rested? Again, we don't know.

I suggest you talk to your doctor to see if you might "borrow" a bi-level to see if it would provide any benefit. In the past, I was able to rent a machine from my DME (with Dr's authorization) to do a trial. I think it cost me about $100 out of pocket for a week.

Anyway, that's my take on your situation.

*Edit: This is not necessarily so. See the postings below. As Guest points out, your Flow Limitations are not driving your S9 Auto pressure to your Max setting of 20cm/H20 and I don't know of any reason to think a bi-level under the same circumstances would, either.

I have no clue to ResScan - but I can only see on the picture provided that the pressure is hovering around the lower limit - if I had to guess sth around 13ish or so.
I don't see there any raise to 20 - not even close. But I might read that wrong.

so there is plenty of room to increase the lower pressure a bit - let's say by 1 and see. the machine more than obviuosely has neither the desire nor does it see the need to raise the pressure. (as there are no flowlimitations to compensate left) so if you want them gone (any further) you have to force that by raising the lower limit.

After reviewing Guest's comment and your chart http://imgur.com/2jnwAgt, I have to agree. Your pressure would seem to max out around 14. From the chart, it looks like your min/max settings (red lines) are about 13 and 20. If that is the case, the machine, contrary to my earlier statements, does not seem to be raising the pressure when detecting Flow Limitations of 0.05. (My observations of this was done at lower pressures and may not be true in the case of higher pressures such as yours). Your chart does show pressure increases that correlate to FL, but the chart is too small to see the value of the triggering FL. In any event, assuming your pressure is indeed only rising to 14 or so, you could increase the minimum to 17 or so to drive the pressure higher to see what effect it might have on your Flow Limitations.
If Guest's interpretation is correct, and I think it is, it casts doubt on the benefit of Bi-level.
In fact, I think there is room for a fair amount of doubt as to whether or not Flow Limitations are the cause of your residual tiredness.

I was pretty sure I never said that - because I had not previously heard of that threshold.

Anyway - - - NOT a problem ! ! !

I have made worse mistakes.

Can I come over to your house & have the other scoop(s) ?

And most people would take that to be more severe.
you seem to be unable to grasp the concept of being able to zoom in on the y axis of a graph, to be able to better view the varying line of data.

it doesn't change the data, or the meaning, just what it looks like.
Here again is the previous 6-22-17 Recliner FLs when the upper level was at 0.5
In this graph, the spikes are shown as getting into the range where the tops are becoming flat

And here it is again with the upper level at 1.0
In this graph, the spikes are not shown as getting into the range where the tops are becoming flat

"Zooming in" should change the scale exactly the same throughout & one should not see this difference.

Stu, those little pictograms that indicate flatness do not apply when you change the scale. They only apply when the upper limit is 1.0
Here is the first hour of my sleep last night showing the graphics from SleepyHead and ResScan.
Notice the Y axis of SleepyHead is set to 0 to 0.25
The Upper limit of ResScan is also set to .25. See each line in the ResScan Chart = 0.05. Compare ResScan Values to SleepyHead.
See the pressure increase, or not fall when the Flow Limit is 0.05 or greater.
These are fairly low Flow LImits. They wouldn't reach the middle pictogram (approx. 0.5) if the scale was 0 to 1.0
If the ResScan scale (upper limit) is anything other than 1.0, you must disregard the pictograms and count the lines. As I said before, the maximum on both your examples is 7 lines high or 0.35. Count them and see (01:00AM).

I do understand & accept what you are saying!

My point is merely that I should not have to "disregard the pictograms and count the lines"

IMHO, the need to do that constitutes a major defect in the ResScan software & how it renders it graphs.

Anyway, I have beat this horse to death.
Time to bury it!

you need to try to comprehend that all you're doing is zooming, and it's making the spikes look taller, the fact that resmed is still showing you the "low means good and taller means worse" on the side, without anything other than that hint,
does not change the fact that the data is the same, it just looks different.

which of these flow limitation charts is worse?

answer, *THEY'RE ALL THE SAME* they just LOOK different, and that's all you've done with your playing with the upper limit.

argue your ux problems with resscan, since they have nothing whatsoever to do with anything other than your interpretation.
