s mode ? elimnate out flow limitation- smooth out flow rate
Hi all,
I would like to elimate my flow limitation, smooth out flow rate.
Should I be on S mode instead of Vauto to get a constant pressure ?
Current epap is 5 and ipap is 10 with ps at 4.4, should I increase ps or epap or ipap or both?[attachment=64690][attachment=64691]
Trigger senstivity is high
RE: s mode ? elimnate out flow limitation- smooth out flow rate
It will be much more helpful to see the standard view OSCAR chart as well, which includes the left panel data summary minus pie chart and calendar.
Most will do better staying with VAuto with a pressure range. Unless needed, timing controls like Trigger, medium is good. Trigger edits for those with Central Apnea have been used, but unless you have them, again medium possibly is better.
Dealing with flow limits may require an increase in PS by a bit.

The "Mask setting" is different for ResMed vs Philips (have not researched other xPAP manufacturers). With ResMed it changes the calculate leak rate, but does nothing to stop the leaks. Philips uses it to calculate air resistance, but again does nothing to stop leaks.
So what it sounds like is happening is you are changing the reporting level sufficiently to drop the leak percentage, but not actually stopping the leaks.
Posting some OSCAR charts would help quite a bit to understand what is going on...
RE: s mode ? elimnate out flow limitation- smooth out flow rate
As a fixed pressure user myself, I see little difference in sleep quality or reported data between S mode and fixed VPAPauto mode.
For example my usual settings are:
Mode BIPAP-S
Pressure 9
PS 4
but I can do the same with auto-adjusting pressure mode using:
Mode VPAPauto
EPAP min 9
IPAP max 13
PS 4

Peace,
Question... Is flow limitation reported while in S mode? Can you look at your data and see? Curious, as the OP is inquiring about lowering or eliminating FL.
RE: s mode ? elimnate out flow limitation- smooth out flow rate
No flow limitations reported in S mode, but still easily visible in flow rate. I do not understand why as the FL data is there, but I assume there is a method to the madness. I even asked ResMed why and all I received back as a shrug.
That is why I use and recommend fixed VPAPauto mode as I am far too lazy to dissect the flow rate looking for FL's when I bother to look at it. Other than that I have not found any real difference to sway me one way or the other.

As much as I dislike replying to myself, I realise that I forgot to add for the OP that it would be helpful to see the complete chart as recommended in the "Formatting OSCAR charts" link in my signature...

Here is an interesting article by Dr. Noah on the subject.

sleep study / bipap settings
I just got the result of my sleep study. See pic for more context. Based of this what would be a starting point for bipap to get rid of the uars
IMPRESSION:
1. No clinical obstructive sleep apnea (G47.33) with an overall AHI 2.1 events per hour.
2. Prevalence of upper airway resistance (G47.8) was greater than apnea/hypopnea.
RE: s mode ? elimnate out flow limitation- smooth out flow rate
Is there something that shows the AHI breakdown for the test? Lots of graphs, but no details.
It seems you were snoring almost 80% of the night. While impressive and regardless of AHI, that means a low quality sleep.
You spent the majority of the sleep on your back. Is there a medical reason why or is it your preferred sleeping position? Supine tends to be where most of us have the mot snoring and apnoea issues.
