Why is my flow shape so spastic & how do I reduce flow limits?
Hi all,
I have been trying to adjust my APAP machine for a month now with minimal to moderate success. Optimally I would wait to see a sleep specialist but I had a 3 month wait (1 more month to go) for a follow up from my sleep study and couldn't afford to wait that long for relief.
Machine: Resmed Airsense 10 Autoset
Mask: Originally F20 silicon, now using the airtouch foam one
Sleep Study:
6h30m
rem latency 360m
24 ahi
Total Arousal Index 45
rem latency: 360 minutes
17 central
102 hypopneas
slept on back
The strange thing is... I am young (25) & normal weight (22 bmi), not the "average patient who is old and/or overweight". I also grind my teeth at night & have a nightguard.
Now that I gave some context, here is the questions I have:
Flow Shape
Its difficult for me to read my flow shape in OSCAR because what I assume is "Cardiogenic Oscillations", is there any trick to see past them or may they be a problem with the machine or indication of "UARS"?
From 3 hr nap I just had.
Flow Limits
How do I reduce flow limits & are mine significant enough to be affecting me?
I've seen some examples of flow limits on the wiki but they usually are stable value rather than going up and down to zero.
Normal, Tired
Better, Less Tired
I read that to reduce FL you use EPR and think that when I set mine to 3 I think my sleep was better, is that the only way? If EPR is the only way then I assume I would need a bilevel to go above 3?
Its difficult to figure this all yourself (while sleep deprived)
to anyone who can shed some insight.
