Hypopneas

is this periodic breathin or are these true hypopneas?

Last night had 60 of these, the night before only had 1 hypopnea all night.

Better overall view, same night

Hi, it would really help if you first told us which model of which machine, what mask, which pressure settings, ? meds, some history, etc. And posting Oscar (or SleepQ) shots with necessary graphs and left hand info (but no calendar or pie chart please) so we could see things in context. If the forum's Oscar posting is full, use Imgur.com's service and leave the link here.

In general, hypopneas so often come way down if you figure out how to not back-sleep... and there are various ways to do that, but again, more info would help us to help you... and please stay in this thread for any Q's and A's.

Airsense 11, F30, 4cm, no meds, Atrial Fib, very occasional A FIb, sleeping in recliner at 45 degrees (back issues)

Airsense 11 what - plain cpap or auto? 4 cm is the machine's default low setting (can't go lower) and most people have trouble breathing at that #, so they raise it to 6 or 7. I'm surprised you didn't ask more about that - is it what your Dr. ordered? If there's no max setting (e.g. 9 or up to 20) then you are in plain Cpap mode (tho' could change to Apap if you have a max setting and script for Apap. A Fib IS atrial fibrillation. Can't comment on whether a recliner full time is a good idea or not, or even if it would still log hypops... but someone else probably will take a look and respond.

It's not an either ... or question. It is possible that those are true hypopneas inside a bit of periodic breathing.

My understanding is that if that is the case, then those hypopneas might be central in nature instead of obstructive.

Last night had 60 of these, the night before only had 1 hypopnea all night.

Can you repost the slightly zoomed out view of this snippet with the pressure graph and the flow limitation graph attached instead of the TV graph?

In order to better answer your question, we really need to know what the pressure is when these clusters are occurring as well as how significant the flow limitations being scored are.

Dr. said leave at 4 cm for the "time being and review the AHI after a while".
DR wants me to call him in two weeks.
Here's last seven days AHIs 0.43 , 3.2 , 2.2, 0.92, 1.06, 0.22, 0.56

last wo days had cough and some flehm - maybe start of a cold

I may have missed it, but could you post some complete OSCAR graphs as described here? viewtopic.php?t=158560. Those that divine truth from OSCAR graphs will ask for it.

Mainly looking for:

Events
Flow rate
Pressure (ResMed users..you have 2 pressure graphs...we don't need both..pick one and use it...doesn't matter which one if we want the other we will ask)
Leak
Flow Limitation (this is only for ResMed users...Respironics users won't have this graph but instead the FLs are shown in the Events graph)

For the stuff on the left side...
Hide the calendar first.
Then turn off the pie chart if you can (Preferences/Appearance tab and remove the check mark for show pie chart).
Removing these 2 images allows much needed statistical information to move up into view so that we get the total AHI and the event category breakdown along with the statistics.
