50 second long central apnea
Hi all, some of my CA events are incredibly long.

If I had woken up and gone to the washroom, I assume the leak rate would instead be spiking for that entire duration right?
Here are some more charts but for obstructive events:

Looks like using CPAP increased my central apneas
P.S I have some previous posts that are less specific, not sure how to delete those
Thanks everyone!
RE: 50 second long central apnea
I noticed you're not getting much input from the community, which may have to do with the lack of clarity in your questions or the volume of information you're providing from the outset.
You have very few CAs over the night, and, yes, they may be a result of your CPAP therapy. How long have you been on CPAP? In addition, EPR can cause this, so you could try turning it down, if that's territory you've yet to explore.
yeah, the leak rate would spike.
RE: 50 second long central apnea
I tried to look at your charts and I can’t make out much from your post. Please use the F12 button on the keyboard and attach them with the button at the bottom of your post. I am sure you will get a lot more help from the group.

RE: 50 second long central apnea
Here are some OSCAR screenshots of my central apneas:
I was prescribed CPAP many years ago, but I've only been able to tolerate CPAP recently.
So I only have 2 weeks worth of all-night CPAP use in total. I have tried turning off EPR in the past though, but I don't recall it making a significant difference. With that being said I will definitely try again.
But I'm also a bit conflicted.. I've heard that flow limitations are solved with BiPAP, but wouldn't that make my central apneas worse?
I suppose in my case, the extended central apneas would be more important than flow limitation problems?
RE: 50 second long central apnea
The central apnea you have is common when people start cpap and as they get use to the EPR the centrals go away. So in the longer term it is important to use EPR... FL are apnea just like Oa/H events only smaller and at a lower amount of obstruction. I have how they are defined in my signature.
RE: 50 second long central apnea
Example 2 is an Arrousal and you are likely tossing
Example 3 may be the same thing, I don't see the termination as your breathing is diminished at the end of the example.
Example 1 could be a CA event but I don't see enough at the beginning to eliminate an Arrousal.
Your "centrals" are not enough to worry about.
On EPR, you are co=ect that improving your breathing efficiency with EPR can and SOMETIMES does increase centrals, but that since the apparently worries you why are you using a CPAP since that does the same thing. The takeaway is for worry about trying it, just monitor the levels and if it gets too high react to it.

Hi, so if I'm tossing does that mean I don't have to worry? Or do I need to find some way to stop my arousals?
I'm mainly concerned because my CA's can be 50 seconds long, which looks scary. Have you experienced/seen things like that, and is it considered normal?

Hmm ok I can accept that. But it seems my CA's are incredibly long. Or am I being overly concerned? I.E do lots of other people get 50 second long CA's as well when they're first starting out? (And for those people it goes away?)
I have no clue so would like to ask those with more experience. Thanks!
