Setup question switching from Dreamstation to AirCurve 10 VAuto

[OceanChild]

Hi everyone!

I let things ride for the last few nights and everything's stayed fairly stable. Changing the trigger setting to "high" after that first night cut number of centrals down by half.

Should I consider adjusting the trigger setting to "very high"? Or does anyone have any advice for what to tweak next?  

My current settings for quick reference:
Mode: VAuto
Max Ipap: 14
Min Epap: 8
PS: 3.0
Ti Max: 2.7
Ti Min: 0.3
Trigger: High
Cycle: Med

Many of our members have found the Very High trigger sensitivity further reduces CA events. We normally like to progress to that setting so you have the high trigger to compare. By all means give very-high a try and see if you have better comfort and efficacy.

Thank you! I really appreciate your taking the time to help.

Didn't have time to update this until now, but I raised the trigger setting to Very High last night and that completely eliminated any central apnea events! Incredible!

It lowered my AHI down to 1.2 for the night, which is amazing on paper, but I woke up unfortunately strangely tired. OSCAR shows the worst of it was a 90 minute period where I had a bunch of events one after the next though the rest of the night was basically eventless. Not sure what happened there.

Nothing to do but maintain the course and keep an eye on it for now. I'm still feeling hopeful!

Post a daily chart please.  That always helps.

I didn't post a chart yesterday because I wanted to wait to see if a pattern began to develop before jumping to conclusions- and one is definitely starting to! 

While switching the Trigger setting to Very High did away with all my central apnea events, it unfortunately seems to be causing me to swallow excessive air during the night. Both last night and the night before I woke up super bloated and uncomfortable. Darn! I feel like I'm so close to finally fixing my sleep issues. Also, I made sure to eat a really simple dinner last night to remove any outside variables that might've otherwise been the cause of the bloating.

Does anyone know why that might happen and is there anything I can do to offset it? Or should I just set Trigger back down to High?

I was really looking forward to looking over the data from last night, but it looks like I accidentally forgot to put the SD card back into the machine yesterday.   The minimal readout from last night that I can obtain shows that I basically had 0 central and 0 obstructive events, but my hypopneas were at 1.5. I wish I had the full info!!

Here's screenshots from Wednesday night and the minimal info from Thursday:

Hm. I'm really not sure what to do.

Just to check to see if my body would adjust to the Very High trigger setting, I'd kept my setting stable over the last week. But despite all my central apnea events being eliminated, something about the Trigger setting being so high causes me to continually swallow a lot of air during the night, causing mildly painful bloating, which I think is triggering hyponea events.

So technically my numbers are down, but I'm slowly becoming exhausted during the day. :/ I guess I'll adjust the trigger back down to High and see if that really does feel better? Beyond that I have no idea.

Let's try lowering your overall pressure settings from EPAP min 8.0 to 6.0. I would like to see EPAP min 6.0, IPAP max 12.0, PS 3, trigger very-high. You don't have much in the way of obstructive apnea, and we may be able to get below your air ingestion threshold with lower pressure.
