Nothing showing up in flow limitation chart on BiPAP-S mode on AirCurve 10 VAuto

I switched over to a BiPAP a few weeks ago, and I'm tweaking the settings a bit.

My Physician initially recommend fixed BiPAP S Mode. I've played around with switching it to VAuto and allowing the pressure to drift up a bit.


I went back to S-Mode and saw that there are no artifacts on the Flow Limitation Chart. I have lots of flow limitations otherwise.

Does the machine not record flow limitation data when it is in S Mode? Or is it just treating my apnea that well? 

(I have way fewer Hypopneas when I am in S Mode vs. VAuto Mode)

When it in "S" mode it has no use for the Flow Limit chart. This is because that data is used algorithimaticly in Auto Mode to determine pressure increases and decreases. "S" mode is fixed and not auto so has no use (though we do) for that info.

The blank chart is there because at some tie in the past you used Auto Mode and that utiized the chart.
