RE: please help me make sense of my central apneas - p4ncaketim - 03-21-2024
I actually rescheduled the drinking plans i had, which was a first date, to today in order to get better data last night! And it looks like I took my mask off soon into the night, so I did not get that data haha. Attaching the data as I noticed that my pressure went up a bit at one point and I had a central apnea that I can't quite understand. I'll hopefully return tomorrow with a full night of data!

Hey! Got a great night of sleep. Please let me know what you think of this data with the settings you mentioned. I attached some close ups of the central apneas i had at the end of the night too.

Results continue to be good/better at lower pressure. It's clear you did not need the higher pressure and you seem more comfortable. The CA events are random junk, so nothing to be concerned about. Do you feel pretty good with this, or do you want lower pressure?

I'd like the lowest pressure possible, however, I'm also concerned with too low of a pressure causing arousals that interrupt quality sleep. I know these arousals may not make it into the AHI. That all being said, this is the lowest AHI i have ever had! If i was going to continue to reduce pressure, what would you suggest? Should i keep the apap feature on or should i find a cpap pressure im comfortable with?
thanks!

Well, we used a pressure of 12/9 to 15/12, and it only moved 0.2 cm-H2O. So, you can clearly drop down to a minimum pressure of 8.0, maximum 11.0 with EPR 3. If your ideal pressure ends up being somewhere in the middle, then this is how we find out.

okay! I'll try that tonight. Thanks!

hope its not too late in the day for a reply - i got half a night with it on. it looks like the pressure needs to be higher than 8. I also got some of those weird central apneas linked together closer to wakeup time, do you have any idea what this is? no problem if no response today - i'll run this pressure again tonight for a bit more data.

The Centrals in question look to me like SWJ (sleep-wake junk). I didn't measure the timing from beginning or ending of that 2nd session they look close enough to the start or end of session, but the CA, first 3 near the beginning of second session followed by 2 more near session end. SWJ meaning is either you're starting to sleep with wake mixing in, or waking with sleep mixed in. Both jumping back and forth between sleep to wake and back cause a breath control conflict between automatic in sleep and somewhat manual while awake. This switching causes a confusion and your breath paused, giving the CA flags.
PS either way it was 5 CA overall. Not something to upset the tea and coffee cart over this.

thank you for that reply! was helpful in understanding.

Definitely dropped that too far. So 12/9 to 15/12 was great. 8/5 to 11/8 too low. That leaves minimum 11.0/8, maximum 14.0/11 looking like the sweet spot.
