2-3am AHI peaks?

[2324Ace]

Hi

Relatively new here and love the sleepyhead data but frankly still swimming in see of acronyms. But love data so very excited.

But what I've noticed is that my AHI peaks around 3am every night. Its like clockwork. Is there a way to adjust for that?

Data from last few nights:

Yes, it's called "apap mode".

Also, please review the sticky post for newbie, especially the section on formatting charts

I figured that since im on CPAP at max setting of 15 all the time that would take care of those peaks. Would those peaks suggest that I may need to go higher and turn on APAP?

OK - thanks for heads up on chart layout/format

Keep expanding, all we need is flags, flow, pressure, leaks, and maybe snore.

The AHI chart is probably the most worthless chart sleepyhead has, I recommend turning it off first thing.

As to your question, 3/4ths of your events are obstructive in nature, and the answer to that is "more pressure".

You've got an apap, why not use it? Set your min pressure to 14, max 20, and see what happens.

thanks.

I'm going to turn it on and see what happens. Was a little more tired today and looked like it was a worse night though had a few drinks and so maybe that was the cause. WIll see how it goes tonight with APAP on.

just out of curiosity why is AHI chart useless? Isn't that ultimately what I am trying to reduce?

You're ultimately trying to feel better. and some of the other parameters count... AHI is relative. But knock of the booze hours before bed because it really does make a difference, and do the Apap thing... though I would start lower than 14... maybe 10 or 11 for a few nights to see how things go (one night's never enough).

[2324Ace]

yeah I know booze doesn't help but had a work thing and the wine was too good to let it pass by

It doesn't tell you anything *useful*... all it does is highlight areas during the night when you're having groups of events, but all you have to do is look at the flags chart to see where the flags are, which tells you *what* kind of events you're having, then you can zoom in (up arrow) and see more of what's going on.

what julie said and said well. the AHI number is built from all the little incidences you have.

to put a finer point on it, YOUR break down of events may not be the same as for other people. you have a lot of obstructives, where as *I* might have a lot of hypopneas. as you yourself ask, why is it all happening at 2-3 am?

i'm NOT the one who can answer that. but working with the good people here, it'll soon be uncovered using the data you provide.

also, believe it or not, your goal is not necessarily to get to zero AHI. you want to get as low as you can while still getting a good night's sleep. myself, i've only ever hit zero once. more important is how i feel when i wake up. a lower AHI can help with that, but it doesn't always happen.

btw, do you know how to get into the menu to make the change from cpap to apap?

good luck!

first off, thanks for all the input. last night was pretty rough sleep. i think i know i have to increase the lower end of the range on my APAP.

Looking at the pressure and the flags, I guess the machine doesnt increase pressure that quickly?

Thanks in advance for any feedback

yeah, confirming your suspicion of needing to increase the minimum. you can either raise it incrementally to 6 or just push it up immediately. i'm always cautious about bumping the pressure too quickly, but that's me. whatever you are comfortable with.

please come back here and let us know how it goes/how it went!

No, your brand of machine is infamous for being very slow to respond, so the min pressure needs to be set high enough to prevent most things from happening in the first place...

You've got an apap, why not use it? Set your min pressure to 14, max 20, and see what happens.

Perhaps you missed the 1 on that... I suggested 14 min, max 20, you set it to 4 min, max 20.

I *strongly* suggest raising the min to 14 for tonight.

2324Ace had been at a straight pressure of 15... needs to get back very close to that for a minimum right away, actually

what? you mean i have to actually pay attention to previous conversation before i spew my silly opinion?

[2324Ace]

thanks guys

I will try it at 14-20 and see what happens......
