UF#2 Improvements?

[MrIvanDrago]

I am starting to dial in my therapy and wanted to ask the group a simple question which may turn out to be a larger discussion. I am now looking at lowering my User Defined Flow Limit #2 (70% Flow Restriction, Event Duration 7.00s) in OSCAR and asking what would be the best way to achieve this? 

Would it be lowering pressure, upping the pressure, lowering pressure support, or lowering pressure support if anything at all? Many of my nights consist of frequent arousals and may have found the culprit, but I could be wrong. I noticed looking back on historical data, that lower pressures had less UF#2 identified, but this could be a coincidence, I'm not sure.

Attached is last nights data from OSCAR:

16.0/12.0 PS4.0 (Been using these settings for 65 days now consistently)

We could better help you if you set up your Oscar chart differently.  We need to see the following items, and these only, in the order listed:

Event Flags
Flow Rate
Pressure
Leak Rate
Flow Limits

We need to see to the very bottom of the Flow Limits, but no further.

I'm currently running in S-mode, so flow limits do not show, just my user defined UF#2. My pressure is fixed at 16.0/12.0 PS 4.0.

Can you show the pressure graph tho?

to me it looks like positional issues. your flow rate noticeably diminishes during event clusters. what position do you fall asleep in? most events seems to be right after you fall asleep?

[MrIvanDrago]

I did notice this as well, but I always sleep on my side at night. The pressure is set to 16.0/12.0 in S-mode so there are no variations in pressure.

Looking to see if I can lower the pressure or pressure support to have less arousals.
