Thank you, to be sure you mean my case is similar? Most of my central apnea events are arousal related?

Also if I switch to a rental Lowenstein machine it could read the cental apneas more accurately?

Thank you

No. You would need an EEG machine.

No...the Lowenstein does/will do the same thing that the ResMed (or any other machine that flags centrals) in terms with what it does to call an apnea event a central apnea. It measures the breathing or flow rate. It (like all the other machines) can't tell if you are awake or asleep. It can only measure air flow/breathing and our awake breathing is irregular compared to asleep breathing so it just calls it like it sees it and that irregular breathing could end up with the machine flagging some sort of apnea event that isn't an asleep event. It's a real event but if you aren't asleep it doesn't amount to much of anything except to point to fragmented sleep when we see it a lot.

It's not a question accuracy as it is the machines just flagging the breathing and no machine measures sleep ..... they measure breathing or flow rate.

Thank you for your feedback.
Can I tell from the OSCAR's data which CA are real and which are arousals?
Also, these "post arousal flags" are harmless events that show I am in the process of waking up and not deep sleeping? Can I read more somewhere?

Buy an Apple watch. It gives a reasonable estimate of awakenings and minutes in each sleep stage.

Or pay to sleep in a sleep lab every night.

Yes, you can learn which apnea events are "real asleep" flagged events and which are post arousal flagged events.
BTW it isn't limited to just centrals.
Post arousal flagged events aren't necessarily totally harmless in that their presence in large numbers points to sleep being fragmented a lot and that means a person isn't getting the sleep stages needed nor the amount in each stage.

Now it's normal to have a few arousals here and there and arousals aren't usually a problem unless we see evidence of a large number of arousals more than the normal arousal/awakening we might have at the end of REM sleep stage.

If you want more discussion about it how about starting a thread of your own and don't hijack this thread with your questions?
