RE: OSA -> CSA?
You treat Flow Limitations by raising Pressure support. in this case you don't because of the Central Apnea.
I don't see the complaints from kuacc912 that would indicate an aggressive need to treat these flow limits.
RE: OSA -> CSA?
Sleep quality, mood, and cognition have not changed noticeably over the past 2 weeks. I am hopeful though.
Thanks for all the input and information. I appreciate it.
RE: OSA -> CSA?
Pressure support (PS) as in EPR or true PS on BPAPs are what I call pressure swings. They have a way of inducing CA.
Those that are proficient at reading OSCAR can see CA events if one presents a zoomed in to about 2 min. segment with a flagged CA within that segment. I can't say it's guaranteed, but there's tells that make it fairly high in accuracy. Obviously not the same level as on a PSG with wires all over. I think leading and trailing flow rate data help to ID these. Differing traces for events will look different somewhat based on cause.
An EPAP Min bump may be a way to address FL, but I don't know if the OP needs to chase those. That's his call IMO.

RE: OSA -> CSA?
With PR machines all we have is to increase pressure so yes, pressure increase may (not will) resolve flow limits and other obstructive events, but raising pressure also can (not will) increase central events, but it is nowhere near as effective as pressure support or ps.
RE: OSA -> CSA?
heavily flow limited breathing, CAs are mostly idiopathic, the pattern at 319 has a slight indication of being CO2 driven.
long term I'd like to see you on a VAuto BiLevel to manage the Flow Limits. Have to know what will happen with your CA events though.
RE: OSA -> CSA?
Might want to keep track of this to see what trends of events you're likely to get.
