Does anyone else do this? SpO2 (new member -ASV)

you will need to check out your heart before using an ASV. They will book a echocardiogram

Only if the Dr feels it necessary.. Resmed's paper on the subject appeared to be more ass covering than scientific.. No evidence of CHF here, and I had one of those catheterizations 10 years ago (the ecg was a little fuzzy after a nuclear stress test. I probably wiggled/moved at the wrong time. clean as a whistle back then - eg no ejection fraction problem, i was the model of a healthy heart.. the catheterization proved safe, but not really necessary.. I can (too easily - fat and out of shape) push 100% MaxHR on my nordic track, and it tires me, but doesnt kill me.

I realize CSV and CHF are co-morbid. Also that the symptom list for CHF and apnea have a large overlap.

I'm picking up the machine on the 4th. If the Dr advises an echo, I'll question him on over-safe medicine - considering that I havent died on my nordic track.. lol

Getting a heart test is a safe bet, but not always a necessity:
"Based on a systematic review and meta-analyses, the AASM update comprises a Standard level recommendation against the use of ASV to treat CHF-associated CSAS in adult patients with an LVEF of less than or equal to 45% and moderate or severe CSAS, and an Option level recommendation for the use of ASV in the treatment of CHF-associated CSAS in adult patients with an LVEF greater than 45% or mild CHF-related CSAS.
" - from AASM
- that doesnt say "test for it first" .
Frankly - I'm looking forward to ASV as a means to avoid CHF in the future.. That Hct and RBC both marginally high - likely from the regular hypoxia during sleep, and the constant need to nap - I see my apnea being the root of all evil for me. I'm really looking forward to that machine , while continuing to exercise and diet..

I'll probably get my question on the O2 dips and how often people present such a dramatic oscillation like mine at the next visit.

ahh.. relief..

I just took my first nap with my brand new asv airflow... This really clears up the oxygen desats.. not event free yet, but dramatically better..

at the sleep lap titration, the 400 minutes that I spent on ASV dropped the AHI from the 70's to less than three..

yes, other people do this, with the oxygen level shown in the original post.. They try to make that go away.

best not to look. That's a nasty graph, you are only going to scare yourself. You lived this long with it, you will probably last a few more weeks till you get your machine set up

Hmmmm? So someone is misusing their spam button.

It does appear so. I saw your crowd clapping just a few minutes ago right after you posted it and now it's gone.

You probably should alert Carolyn and let her slap the offenders hands. If you don't they can keep doing it and getting away with it.
She can easily see who did it and take appropriate measures and will do it for misuse of the spam button.

I have a pulse-oximeter built by Massimo for PR that connects directly to my PR 960 ASV machine and recently it began to show this same type of reading after years of recording quite nicely.
I cross checked with my CMS 50F oximeter and concluded that the one in the machine was failing. Now it is disconnected and on the shelf. Unfortunately, PR has discontinued support for my Oximeter attachment so I can't get the replacement part I need to fix the problem (the part is the fingertip probe.) I can get one that looks the same from Massimo but the pinouts are different and my machine doesn't "see" the sensor even though the cable end is compatible.

Looking at your report, it shows 48% artifacts and that is indicative of significant motion artifacts. Any chance that you are having restless leg syndrome or one of the other movement disorders? You might check with the lab and ask them for a copy of your full report (you will need it anyway) and see if excess movement is reported. I would think your O2 sensor was bad but you don't get this type of issue while wearing it while awake. So, excess motion is likely the culprit.

The reference to ASV machines being not appropriate for some cardiac patients refers to a study done by ResMed in which they found that congestive heart failure patients were at increased risk while using an ASV machine. Since this does not appear to be an issue for you, no need to worry.

The suggestion to change the subject line to mention ASV is a good one even though your issue is SpO2 related.

what idiot doctor wouldn't book an echocardiogram and leave himself open to a lawsuit where he will never get insurance again?

someone is posting spam

really a picture of a bunch of wild people waving their hands
that is PURE SPAM that you posted

xxx, you have a spam button?
