New to CPAP - First Night Great, Second Night not so much

[oasised]

Hi Guys,

Bonjour - So I've changed the settings, exhaling seemed to take a tiny bit more effort but I would genuinely say it was no bother. I woke around 7am this morning - checked my Machine and it said I had an AHI of 2.5 throughout the night - pretty good I figured. Did some reading on my phone for a bit and decided to go back asleep for a while as I've got a very long day ahead of me. Put my mask back on, woke up later and my AHI had bumped up to 7.5 just because of that little nap - big clusters of CA's.

I have to say, when I woke up around 7 I wasn't feeling the best - definitely felt I could have done with more sleep. After I woke up after my little reading break I felt 100% better and now feel like I'm ready to take on the day  - despite tripling my AHI in less than 1 hour!

I've attached my screenshots from last night/the past hour.

Sleeprider, you mention position issues - could this all be related to how my head is positioned through the night? Is there an optimal placement or anything I should be aware about?

That cluster of centrals is again bouncing around your CO2 triggered apneic threshold. The lack of previous history says this is Treatment Emergent Central Apnea. Typically this is given 2 to 3 months to clear up. Then if it doesn't a move to an ASV that WILL resolve it.

You and your doctor have connected your sleep apnea to a driving factor for your AFIB. Because of this you need a discussion with the doctor that made that conclusion. It needs to include facts.

1. You have Treatment Emergent Central Apnea.
2. In a lot of patients, not all, it greatly diminished over 2-3 months. Waiting is the typical action.
3. An Adaptive Servo Ventilator BiLevel, preferably the ResMed AirCurve ASV, an advanced CPAP machine, will resolve it overnight.
4. Question, Is the ASV where I should go knowing that it will provide near zero AHI virtually overnight based on my AFIB?

Please have this discussion.

Normally I would decrease your EPR to zero to try and minimize your Central Apneas while leaving a few, helping your body adjusts to lower levels of CO2. With your AFIB I'd like your doctor to get involved with the direction.

I would agree with this plan bonjour has posted. If me, I'd want this in the medical file sooner than later.
