First night on AUTOpap need help interpretting

So I was titrated at 8cm 5 years ago and had been having severe symptoms every 3 days or so lately.
Yesterday, I replaced my cpap with new apap machine and replaced the hose as well. Mask stayed same
I set the machine to run 8-20cm per advice here. (My old setting and higher)

This morning, I FELT AWESOME!
Working the software was a pain and I needed my IT person to remote in to help me work the software from the machine.....the SD card was corrupt!

Heres what I could pull off

(Again I set min at 8 but it seems that it went lower??!
My titration (old on cpap) was

6 cm 2
7 cm 196
8 cm 302 0 apnea .2 hyponeia
9 cm 19 0 apnea 9.5 hyponia
10 cm 1 0 apnea 0hyponeia

no higher pressure seemed to happen or be listed

Avg 90th percentile 7.9
Avg leak 22.6
lowest leak 16
highest leak 28

So what does this mean?

It looks like my old pressure was fine (or was it?) (meaning the machine or hose was bad??)

Will I feel this good going forward???

Do I need to change the range??

Im so new to auto (not cpap or apnea)

Thanks in advance! Fred

Unknown.. you need more nights to see.

Not really..it never went above the 10 cm...the machine won't go up unless it needs to go up for some reason.

I am not familiar with this machine. It may have some exhale relief in there that is dropping the pressure a bit during exhale and this will reduce the overall average pressure.

Again..unknown. No way to know for sure. We wonder but there is no way to know for sure unless all components were thoroughly test.

From the data shown here...leaks are well controlled and the machine appears to have done its job properly and you feel great.
You just need more nights of using it to see if it holds true.

Perhaps your body likes this machine's algorithm better. It can happen.

Can I (and I know its only first night) infer that I did need a slighty higher ( 9 and even a 10 one time) pressure than I had at cpap 8 ? Could that subtle a difference cause the lethargy???

I seemed to have NO apneas but some hyponeias.

What is the difference? It seemd that the machine responded in kind to from 8 to 9 and even once to 10 and that was all it seemed to need!

Sure could do that and yes, subtle differences can and do make marked differences sometimes.
You might also infer that you might have done fine with cpap at 8 for most of the time and just some of the time might have needed a little more pressure...like for supine sleeping or REM stage super duper events. That's what I called them when I had them. I used APAP with 10 to 20 range..most nights stayed around 12 cm or so but some times I would see 18 cm...normally associated with what appeared to be REM stage sleep where I am documented much, much worse. Didn't happen every night all the night but fairly regularly show up.

I switched machines..went to BiPap on a fluke experiment. AHI pretty much runs what it did on APAP maybe a little better.
BUT....I am averaging about 50 minutes more sleep for some strange reason...and I am feeling better..actually remarkably better in terms of daytime sleepiness. Why the difference in how I feel? I can't tell for sure maybe the extra sleep helps some and maybe my body just likes bipap more.

That makes sense since my old cpap was fine some days (@8cm) and not on others! Now that Ive allowed it to "rise to the occasional occasion" It may just be that auto was the answer (for those not so great days after)

The use of ambien may also be part of the reason it slipped upward as also a 20 pound weight gain (since last titration 5 years ago this week)

I bet if I lost the 20 (or more) the 8 will be fine again...maybe!


Thank God for Auto!!!

I didnt want a new sleep study$$.... but yet I was miserable (some days)
Insonia made studies 2x as difficult too and a study may have missed these time to time events !

Thanks for weighing in for me..Im learning the ways of auto!
