It is with much happiness that, after my first night back on the ASV, I report an AHI=0.7 (AI=0) after about 10 hours of sleep. That is my best number ever. My previous best on the ASV was about AHI=4. Last week on the S8II Auto I was consistently returning AHI=8ish. I used EPAP=7.0, PSmin=4.0 and PSmax=10.0 to try to push up my Minute Volume a bit (couldn't help myself!)

When I get around to setting up Rescan I will have a look at the squiggly lines and post.

Thank you. BTW, my minute volume mean was 5.4L/min and respiratory rate mean 13bpm. For the first time in a long time I have been out doing physical labour in the yard this morning - scrubbing pavers. Aaaah, me old mate Adapt SV!

That is nothing short of WONDERFUL, blizzardboy!

Wonder if your trial ASV machine had a problem?

Well, "IMHO", that's a pattern of a patient on a machine that doesn't like sleep instability.

Perhaps. But I doubt blizzardboy experienced sleep instability all night long during both nights. I think we can try to test that conjecture by comparing/correlating tidal volume oscillation density with much improved sleep/AHI nights like the one blizzardboy just reported.

Cool!

-SWS wrote:Lemme do the devil's advocate thing a bit with your take on hypocapnia and sleep instability, which I think is probably the correct take...

Muffy, your take might be perfectly correct. I'd like to allow the upcoming data to first shape patterns, if any, related to night-to-night variability.

What was the cause of the food sticking? What did they see on endoscopy that led them to believe you have GERD, and what did they see to make them conclude you're under-treated?

My esophagus diameter was narrow because of GERD swelling. So the lobster tail stubbornly sat there in my esophagus. When they administered that first endoscopic exam there was severe redness, swelling, and some tissue damage/scarring IIRC. By contrast the residual signs of acid exposure were only slight during the last exam.

Congrats again, blizzardboy!

Thank you too. I am now also wondering about faulty trial machine. Please look at:

to see my MV and TV detail from last night. Please note that I was awake at each end of the 1st sleep period.

Other than the tiny area noted:



that's another awful night.

Or at least, the machine didn't realize he was wearing it.

Hi Muffy, I don't understand what you mean by this, can you please explain. Cheers.

8a is missing the data block where you usually have your "good" sleep:



Or the clock is AFU.

Or that was you "experimenting".

And if that's the case, your "wake" experiments look a lot like your "sleep" experiments.

Given that is a Saturday, maybe I had a nap in the afternoon.

A NAP!!???

Hold that thought...

Anyway, that night similarly shows only a brief period of stability:

BTW, if that's a nap, your nap quality is REALLY poor.

What are you seeing that tells you my nap is poor? BTW, I often wake up from naps feeling drugged and grumpy.

Large swings in tidal volume and way too high respiratory rate.

"IMHO" it's your sleep hygiene and sleep quality that is the major problem.

If you're napping that close to when you normally go to bed (or when you should be in bed already):



you're going to wreck that night's sleep.

You need to consolidate your sleep into a well-defined block of sleep AT NIGHT.

At your age, you don't need a nap if your sleep architecture is acceptible.

You wake up "feeling drugged and grumpy" from your naps because TAWTFPTPO.

Reread (or read) the sleep hygiene stuff.

Are the times on your DLs accurate, or do they follow the "Arbitrary Australian Time Zone Assignment" (AATZA) as well?
