Quiet air elbow issue Maybe

[clownbell]

Is there a reason why the OPs settings are so high? As I understand it, high pressures can cause/exacerbate Centrals. The high pressures flush out more CO2, causing the amount of CO2 to be too low, which in turn causes the body to go on "pause," not breathing (which is a Central) until the CO2 builds up to the level at which the brain sends out the signal to breathe again. If there is a legit REASON for the high settings, that's a whole other thing.

I reserve the right to be wrong, and will be corrected by the experts. Just asking the question.

Thats what my specialest prescribed

Maybe with the old elbow venting more i didnt get the CAs but the new quiet is working to well at this pressure
Goood to know seeing specialist for update in next few weeks

If you think the new mask may have resulted in a different optimal pressure level it may be worth changing to APAP mode and setting a minimum pressure a bit below your current pressure (e.g 10-15 instead of constant 15) to see what effect that has. I know that for me, changing from a full face mask to a nasal mask caused a significant drop in the average pressure the Autoset mode was applying.

I suspect that there's a chance the doctor's plan with the AutoSet, an APAP, and straight CPAP pressure is the "avoid Central Apnea" plan. Variable pressure can increase CA in those already having CA events. At 15 however, I'd rather be on BPAP for comfort. BUT in cases of higher CA, the BPAP without backup rate like a VAuto will almost always make the CA worse.

Just my opinion, but your abundant CA and the doc's actions indicate your Centrals are known to them. And they're attempting the cheap way to treat, by not treating but avoiding. And you'll see they're not avoiding any CA here. Again just my opinion, but ASV is your best answer. This is either idiopathic or pre-dominant/pre-existing Central Apnea.

That is characteristic of Treatment Emergent Central Apnea

Your EPR is considered a comfort feature and is set at 3, set EPR=1 as that should significantly reduce your centrals this is an agressive move, expect to try either EPR=2 or 0/off depending on results. Also your obstructive events may go u with the decrease of EPR, we are looking for a ballance between obstructive and Central events.

[Gideon]

Clown Bell, EPR has a much larger impact than pressure does so we try that first. The settings are obviously working well for obstructive events
