lower APAP pressure
Hello fellow pap'rs:
I've posted before about feeling bad upon awakening every morning. I try every day to make the best out of these times and believe they will improve. So here is what I am finding.
I have lowered my starting APAP pressure from 8cm down to 6cm.
I am feeling better in the mornings, and am relieved. My upper pressure remains the same (12) to reflect my 95th percentile of 11.8.
Although my median pressure according to the data is 8.5-9, it just seems to help to have this base pressure lower. Since my ResMed 9 autoset should continue to find the right pressure to keep my airway open, I am fairly confident that lowering is OK. My O2 is staying stable above 94 all night, and I know this is good. Just wanted to run this by my masked friends to be more assured. Whatcha think?
Thanks![/font]

RE: lower APAP pressure
ppowers, can you let us know what your AHI is over a period of time.
I think it's Ok if it helps you and your still getting good results.
Not sure if you want to discuss it with your specialist to confirm.
One of the reasons behind using an Autoset which I assume you are using is the comfort value
(you may want to update your profile with the model next to the machine name)
You can compare your results over the next couple of weeks versus the previous two weeks.
The two things I use to know whether my treatment is working or not is my AHI and more importantly
how I feel the day after using itSmile

RE: lower APAP pressure
There's really only a couple of things that are important: Is the therapy managing your apnea? (What is your ahi?). Are you sleeping well and are you comfortable?

It sounds like you're doing better on the feel good things, so if you're also doing well on the ahi things I'd say you're just fine.

My AHI is always below 1. I use the resmed 9 autoset.

RE: lower APAP pressure
If your AHI is below 1 and your median is 8, why are you lowering it? It most likely is not going to make any difference whatsoever one way or the other. It might cause the machine to work slightly harder to react to what your airway is doing but only a slight bit.

By making the change, when a change may not be necessary, you are upsetting the balance. The machine now has a wider range to play with an, like I said, it could take it longer to react. This could cause the AHI to increase although only slightly since your AHI is so wonderfully low. Which is my point. If my AHI was that low? I'd not touch a darn thing.

RE: lower APAP pressure
If it makes her feel better and her AHI does not go crazy then I think she has made a great improvement. She made the change because she got up every morning feeling lousy. Sounds like a good reason to me.

Keep on truckin' ppowers

Best Regards,

RE: lower APAP pressure
It seems odd that change would cause a person to feel better.
Except for some very small second order effects, the therapy is unchanged.
I have to wonder if there isn't something else going on.

RE: lower APAP pressure
Perhaps it is the getting to sleep that is getting to ppowers.

I'd think that instead of lowering the minimum pressure, ppowers, you might want to try the ramp feature instead. It'll do the same thing (lower pressure to start with so you can get to sleep), but get the pressure to where you seem to need it (without waiting for events to happen to boost you there).

Ok so here's my reasoning. If the machine goes back to your base pressure as the baseline, and my AHI does not increase, isn't it better to use the lowest pressure you can while optimizing your therapy? Maybe I'm mistaken. Isn't that how it works?

RE: lower APAP pressure
Can you post a plot of a typical pressure curve over a night?
Is it really retreating to baseline pressure?
A Resmed APAP raises pressure aggressively in response to flow limitation and snoring which are predictors of impeding OAs.
It retreats slowly. (Like ANZAC troops -- unafraid to attack, slow to retreat. That's for my brother's!)

Still doesn't seem logical that changing baseline from 8 to 6 would make a difference in how you feel.
