Missing flow limitation data on ResMed AirCurve 10 S - upgrayedd - 10-29-2019
When downloading the data to OSCAR or ResScan, there's no information for flow limitation. The DME is saying this is a ResMed issue and ResMed is saying this is a DME issue.
Flow limitation isn't shown in the statistics section or on any of the graphs, both daily and overview. In the OSCAR preferences I have checked the boxes for flow limitation for both events and waveforms. All of the other info shows up fine.
Machine: ResMed AirCurve 10 S
Run Hours: 462 (the machine is new to me)
SW: SX558-0505
OS: Windows 10 Pro, 1903
OSCAR version: 1.0.1-r-1
ResScan version: 5.9.0.2629
Is something going wrong? Is the machine even recording the flow limitation data? Am I just missing something?

Flow limitation is not recorded on the Aircurve VPAP S or on any Resmed CPAP model other than the Autoset when in Auto mode. Flow limitation is an important metric in the auto-pressure adjustment algorithms for Resmed, but it is not needed on the fixed pressure models. Even the Autoset will not record FL in CPAP mode which is why we frequently advise setting a pressure range with the same minimum and maximum pressures. Not sure about the Vauto in S mode or CPAP mode. That is my best understanding, and if anyone has an S9 or Airsense 10 elite, VPAP S or ST that records flow limitation please correct my misunderstanding.

Pretty sure it doesn't, which is why I always use VAuto mode, even if I want effectively fixed pressure.

Thanks for the responses. The S9 VPAP does record flow limitations. I was expecting the AirCurve 10 S to give the same info.
For me at least, I seem to have better sleep with lower flow limitations. Also, I seem to have more apneas and flow limitations when on my back, so I'd like to use this info to help train myself to stay on my side. The attached file is a good example. Around 130 I had a bunch of flow limitations but no apneas. As it stand now, my AirCurve 10 S would have completely missed this event.
