Centrals are Rising?

Finally !! "should be exchanging my BiPAP for ASV this Tuesday!!!!

Good Stuff! I too had to jump hurdles to get what I needed. The ASV will fix all your issues i would assume

Interesting, somehow I'm in the same situation. I have many centrals but my doc said to me that there are not CA, you have arousal due to my anxiety, drepression and limb movement(restless leg55/h).
Tell me please, what kind of ASV do you need - VPAP/BIPAP Auto ; VPAP/BIPAP ST; VPAP/BIPAP ST-A; VPAP/BIPAP Adapt SV Auto; VPAP/BIPAP COPD ?

The only real ASV in your list is the VPAP Adapt SV and I think your model names are from old model series names in the ResMed line.

BiPap is a Respironics marketing term for bilevel and ResMed has never used it.
VPAP is the ResMed marketing term for bilevel pressures...and VPAP itself doesn't necessarily equal ASV function.
You can have bilevel and it not work as ASV.

In general when someone has both obstructive sleep apnea and central sleep apnea you need a machine that will treat both.
In the S9 ResMed Series...that would be the S9 VPAP "Adapt"
in the new AirCurve 10 Series from ResMed that would be the AirCurve 10 ASV

ASV is Adapto Servo Ventilation...or non invasive ventilation support. The machine will breathe for you if you don't on your own which is what a central happens to be.

Thank you Pugsy for clarifications, real help.I saw those models in Secondwind list. So, to treat the CA we need VPAP Adapt SV (from resmed). And Respironics don't have something like the same(for centrals) ???

Right now the latest model in the Respironics model line that will treat both Obstructive Sleep Apnea and Central Sleep Apnea is the PR System One model 960 or the slightly earlier model 950.
PR System One BiPap AutoSV Advanced
There is an even earlier model in the Legacy series machines and I think it's model name is Respironics Remstar BiPap AutoSV Advanced.
So Respironics does offer additional Bilevel machines along with central/Obstructive treating devices.
Some are just regular bilevel like the ResMed regular bilevel and some have other specific functions like for people with COPD, etc.

Secondwindcpap has a substantial inventory of some of the older model machines both in cpap/apap/bilevel modalities and sometimes that list VPAP and BiPap in the same product description. They don't always use the exactly correct model name in there product naming or description.
Not a big deal once someone learns the real name and what the various models will do.

the vpap adapt sv is an old, long discontinued model.

the term 'bipap' only applies to respironics, it's their version of 'vpap'.

if your centrals aren't centrals, then an ASV isn't the appropriate treatment.

Thank you again Pugsy, I understand now.

Hi palerider, honestly I do not know if my centrals aren't centrals, I'm so confused.
My S9 auto- resmed (sleepyhead) it shows that i have many CA\ but when I did the sleep study last month (many wires coming out of my head) did not show anything (the problem is that I slept with a sleeping pill and that I think it's cut my centrals).So I think that the sleep study it was inconclusive because I slept with ambien(at home I sleep without) and the two sensors were not in my nose(I slept with my mask&cpap). Resulted that, I had some OSA's and 55/h restless legs , 61% decrease in sleep efficiency, reducing with N3 (15%), REM (14.7%).

there's another discussion floating around in the first page or two about true and false centrals.
also, watch this: https://www.youtube.com/watch?v=xallwxPCg84

all the machine knows is that you quit breathing, but your airway was open, whether you were truly asleep at the time, or moving around, it has no way of knowing, without the wires stuck to your skull.

watch the video, then look at some of your centrals on sleepyhead, and see which they look like.

Centrals generally occur for three main reasons.

1. Improper pressure settings or Equipment If you had central apneas in your dignostic study (first sleep test) and you still see them on your report, then you need may need a different PAP modality, like ASV or bi-level with a back up rate.

2. PAP inducted Centrals If you did not have centrals in your diagnostic study they could be caused from a PAP pressure that is to high (these are known as PAP inducted centrals).

3. Centrals from arousals The last reason you may have a central is from waking up. After you wake up your body natural has a central apnea, these centrals should not be treated with PAP therapy.

In conclusion if you see a trend of increased centrals you need to see your sleep specialist and possibly have and titration study. Generally seeing centrals like this are an indication that ASV may be needed. However I am not a Doctor, I am just a Regisiered Polysomnographic Technician offering my non-diagnostic advice.
