Early morning central clusters

Yes, it is very possible that learned behavior is playing a part. Habit.

To be honest...I doubt it is one single thing but instead it is probably a combination of things.

And what would the pressure be responding too? For me a OSA diagnosis was a huge surprise. The only risk factor I have is a mildly deviated septum which I hope correcting with if not fix reduce the issue.

Flow limitations are probably what the machine is responding to. Reductions in air flow that aren't enough to earn a flag of some sort but enough for the machine to sense a reduction in the air flow from something and try to stop it from happening again with more pressure.

Nasal congestion will do it....the machine doesn't know if the reduction in air flow is in the nose or the airway behind and down the nose.

So a flow reduction somewhere causes the machine to think "OMG, reduced air flow...the airway must be narrowing...it's not bad enough to earn a flag but it might grow up to where it could really be a big problem and earn a flag...so I am going to try to kill it and keep it from coming back".

These machines respond more to flow limitations and snores than we ever realize...and we don't see it like we do the flagged events.

I’m a little confused.....

If I’m understanding Pugsy correctly she is saying that the pressure is only looking like big jumps because of how I have it set and that 7-11 isn’t that big of pressure change.

You are saying however that it is possible that 7-11 pressure differential is possibly too much and is a possible cause for wake ups?

No, it's my opinion that the pressure changes are immaterial, ASV users experience far more pressure swings on every breath!. What I'm saying is possible is that the breathing event that caused the pressure jump is what's causing you to wake up, after all, that's what they're documented to do, snores and flow limitations aren't in the ahi, but they do knock you out of sleep stages and cause arousals.

Ok I’m pretty sure I understand now.

Palerider you are wanting the minimum to raise then so the machine is almost in a pre-emptive state rather than a reactive one when it needs to up the pressure then?

Based on my Oscars where would my minimum pressure need to be in your opinion?

I’m at 6.4 now. The aerophagia has been a non-issue for about a week at this level so I’d be willing to endure a few days if it’s possible to not wake up 6 times a night.

Since I haven't seen any recent charts... I'd suggest just bumping it up slowly, as little as 0.2 every few days, and give yourself time to adjust... that worked for Zonker when he was fighting with aerophagia, and he ended up feeling considerably better, and easily tolerating pressures that previously caused him pain.

Thanks I think I will try and see what happens.

Totally unrelated question but now that I’m getting better seal and no leaks I’m really noticing condensation that is building in nasal mask and getting nose wet.

What is the best way to deal with that? My humidity level is set at 4 with a temperature of 80 for the hose. My room is probably 65-68 degrees at night.

I just turn up the temp on the heated hose a little.
Sometimes just one degree is all that is needed.
I don't really want to warm up the ambient room temp and lowering the humidity setting doesn't always work if the moisture that is condensing in the nasal pillow is from the moisture in our own exhaled breath.

This is often referred to as rain out, the differences in temperature between the humid air and ambient temperature causes the humidity passing through the hose to condense back into liquid.

Consider one or more:

• Decrease humidity setting
• Increase hose temperature
• Increase bedroom ambient temperature
• Run CPAP hose through a cozy or under blankets to keep air warmer

to the OP-yes, he's quire correct about how i tackled my issues with aerophagia. i took what i consider a RIDICULOUSLY long time to deal with it. but after visiting this forum for many months, i finally convinced myself that i had to raise that minimum pressure. so i plodded along, raising that .2 and leaving it for hell even a week or two. and i'd back off of it immediately if the gas pains got worse. but eventually, i made it.

you will too. and i'm pretty sure that i'm the sterling exception that enforces the rule.

good luck!

Zonker were you experiencing a lot of wake ups or what was your reasoning for wanting to raise it?

What pressure did you end up at?

My charts are on the first page of this post what do you think my endgoal for pressure should be ?

i am now blowing 15.2 min and 20 max. for the longest time, i was convinced that i couldn't raise my pressure past 7! i still find that hard to fathom, but it was true.

my first goal was to lower my ahi. mind you, i was NOT chasing zero, as i have always felt that was not a realistic goal. but i am one of the few that can actually feel the difference in my sleep quality when my ahi is, say 0.50 and 1.50. it's a very subtle difference but it's there. others here have reported they can't really feel the difference.

just another example of how we are all different.

once i got over my aerophagia and got a nice low ahi, then i tackled the multiple wake ups. if you want to wade through it, here is my saga-

viewtopic/t173195/zonkers-cribdoes-humi ... nkers+crib

the title is weird because i edited it every time i wanted a new question answered.

what my wake ups boiled down to was sleep hygiene. if you are interested in that without plowing through my thread/novel, i don't blame you.

basically, i'm now watching what i drink and eat. also, more physically active than i've been in years. that's not to say i do a heavy workout or run miles per day. just reasonable stuff that makes me slightly more fit.

oh, and i don't have enough knowledge to give regarding pressures. but i'll go take another look.

sorry for the rambling post.

but it's either type or go do some of that "reasonable stuff" i mentioned above!

ETA: i would say to raise that minimum pressure at your own pace. this gives your machine more of a "running start" at tackling your events.
