S9 VPAP Adapt question

My experience also. My machine was one of the early S9 VPAP Adapts, so maybe that is the cause of this.

Sorry Stormynights and Jeff. Try these instead: To view your Flow Limitation graph, open your patient account in ResScan as usual and then select the REPORT menu. Then click the CUSTOMIZE tab. Expand the Detailed Graphs by clicking the “ (+) ” next to it on the right side of the page (under Report Layout). Then do the same on the left side of the page (under Available Items). Now select Flow Limitation and click “Add”. And then click OK.
---- OR ----
To view your Flow Limitation graph in SleepyHead, open SH, click the File menu and select Preferences. Then select the Graphs tab, check the box next to “Flow Limit” in both the upper “Daily Graphs” list and further below in the “Overview Graphs” list. Then click OK and you will have added the Flow Limitation graph to the other graphs you can see.
Let me know how you do by PM or post here.

I think it is as Jeff said that ours are the older machines. I have just finished rechecking and I have the graphs checked but they are not showing.

Same here.

This is Resmed's description of their S9 VPAP adapt:

Dated 2012

The page before last is this:



Notice on the bottom of this page that there are two SETTINGS shown for ASV Mode or ASVAuto Mode.


Page #3 in this Resmed's description is:




In the center of this page I read that:

The algorithm achieves this by detecting such apneic events
and quickly changing the Pressure Support to control events
and normalize tidal volume, thereby normalizing breathing.

It means to me that if the machine is set at the "correct" set-up, in the ASV Auto mode, it should then detect apneic events as obstructive, snore, and flow limitation, and automatically treat them by changing Pressure Supports. So we should NOT see any of these events left untreated.

However, as mentioned by John Fisher above, there might be patients who are sensitive to the automatic changing of pressures by the machine. In such cases the non Auto mode could be chosen. But then if the set-up pressures are not set optimally, the machine would NOT treat those events completely, and they could be seen as such in the output graph data from the machine.

Agreed. That was the one major feature missing from the ResMed ASV. Now they're really interchangeable.

Mine was new late spring 2011. It was one of the first s9's.

I got mine on Craigs list.
