Respironics dreamstation Bipap AutoSv software

Because of aerophagia and central apnea with my "regular" dreamstation ABAP, they now assigned me a new machine "Respironics dreamstation Bipap AutoSv"

Any software that works wit it? I have try sleepyhead beta and Oscar, they sorta work (read the card), but I don't get any of the useful info (only flow data).

Thanks.

Those plots shouldn't be disabled. Make sure you haven't accidentally turned something off in the graphs.

Encore Pro will work. Windows only software though.
You can go over to the apneaboard forum and register and log in and then you can see the threads for how to get Encore Pro.
They are hidden until you log in.

You won't get much more than you have with OSCAR though. Encore doesn't show the details as much as OSCAR does.

Thanks,
I have not disabled anything, and checked again the prefs and I don't see anything disabled, most likely the software juts can't parse my machine's data properly.

I'll try windows software when I have a chance.

it seems it's a known issue and a new beta might help, asking about that on the apnea board.

I was able to get the beta version source code (beta3) and build it and it now works !

Quick question, it shows a lot of snoring still, would a chin strap help with that (they provided me one), or using a Full face mask rather than the Eson2, or does it juts mean I need more pressure ?

Higher epap

As PR said higher EPAP and turn off the VS2 events as they just add noise and are not helpful


Is your min and max ps really both 0 as that prevents the ASV doing its job I guess that’s miss read settings.


What are your machine settings as I don’t see why it did not increase pressure to treat the CA’s in the middle of the night

Interesting about vs2, I think most of my snore events were those.

I do also have a lot of CA events (43) :-/

I *think* the epap values were just reported wrong by Oscar, but I'll dbl check as the tech that was setting the machine seem she was struggling with this model - I felt like I could have helped

Anyway the prescription is Epap 6/9, i'll probably let it be for a bit assuming it's set correctly to 6-9 and not 6-6.

so the place I pick up the machine had set it all wrong : facepalm
prescription is epap 6-9 with backup rate of 12, instead it was set to 6-6 with no backup, I could tell the lady there didn't know what she was doing.

Anyway I now set it now to
Press:9, epap+ : 9, epap-: 6, ps+:3, ps-:0, BPM:12, TI:1.2

Which I think is what matches the prescription(not sure about ps-) , let me know if not, I'm asking the sleep clinic to verify as well.

The settings still sound wrong



Philips recommended settings as a starting point are here http://incenter.medical.philips.com/doc ... %3D9792335

Page 14



• Set EPAPmin at 4 cm H2O - I would set at 6
• Set EPAPmax 20 cm H2O
PSmin at 0 cm H2O - I would set at 3
• Set PSmax to 20 cm H2O
• Set Max pressure to 25 cm
H2O
• Rate to Auto
• Set Bi-Flex to patient comfort - I suggest turning off if you set min PS to 3 if you set ps min at 0 then add some flex



The settings by the sleep clinic will not allow the ASV to do anything

Thanks Jas_williams, I get what you are saying, I think, but my prescription says Epap 6 to 9 (9 max), I agree that it might be better to let the machine decide how high to go, but I think they are starting me with a max of 9 because of the aerophagia issues I had been having with the ABAP machine with pressures over ~11

-- Prescription --
This was a challenging titration study due to sleep onset and treatment emergent central apneas and aerophagia. Dr. <del>, the attending-interpreting physician, suggests a trial of Bilevel PAP (positive airway pressure) with a pressure setting of 9/6 cm H2O with a back up rate of 12.

While my AHI (and sleep) was not awesome last night (~12), CA score did improve, the machine kicked in on those CA events and that seems to have worked (before midnight is wsj, and the cluster around 1:15 might be too, not sure if waking was the cause or the effect though)

No sure what's the deal with the Hypnoea stuff though, that's way higher than usual.

I can't find a clear explanation of "Pat. Trig. Breaths", it seems to be the average of breath triggered by me vs the machine, in which case only 62% by me on avg doesn't sound good, but no idea what a normal range would be here, ditto with "timed breath", what is that about and is that something to worry about ? I think those are new with Bipap.ASV.

Thanks again.

that bpm seems much to high for me?

I'm glad you got things working with OSCAR. As you noticed, the 1.0.1 release didn't really support the DreamStation autoSV very well, but we've made a lot of progress since then.

Based on this your PS should be 3 and our EPAP should be fixed at 6, not EPAP 6 to 9. If your PS is set to 0, there's no such thing as a backup rate: the machine can't increase inspiratory pressure to stimulate your breathing!

(In fact, in alternative therapies for central apnea, this is precisely what they do to an ASV to make it act like a CPAP machine!)

Looking at your Friday chart was alarming, given the lack of PS and the high untreated CAs.

The way your prescription is written PSmin and PSmax should both be 3.

Breaths", it seems to be the average of breath triggered by me vs the machine, in which case only 62% by me on avg doesn't sound good, but no idea what a normal range would be here, ditto with "timed breath", what is that about and is that something to worry about ? I think those are new with Bipap.ASV.

PTB is what you think it is: it means you're only initiating breathing 62% of the time. However, with a fixed backup rate of 12 breaths per minute (bpm), that could mean that your natural breathing rate is slower than 12 bpm when you're sleeping. On the other hand, your 95% breathing rate was 16 bpm, so this could be genuine.

Note, however, that a low PTB is precisely why you're on a machine with a backup rate: you're experiencing central apneas, and the machine is trying to keep you breathing. I found that I felt worse on mornings there my PTB% had dropped, but the machine did reduce the number of CAs successfully. Are you consistently low throughout the night, or are there periods where you're breathing on your own and periods where your PTB% crashes?

A "timed breath" is the event where the machine switched to IPAP pressure on its own, in your case due to the backup rate of 12 bpm. So the 48% of the time the machine breathed for you, you should see a timed breath flag on the graph.

In my experience, a fixed backup rate made my aerophagia much worse, I think due to a timed breath out of the blue (as far as my body was concerned). With an "auto" backup rate, I experienced less aerophagia, since timed breaths were generally pretty close to my then-natural rate. But even that disrupted my sleep.

A useful tip if you happen to move onto an "auto" backup rate: pressing the ramp button will reset its idea of your breathing rate. So if you wake up breathing fast from a vivid dream and want to breathe at a natural rate, you can just press ramp once and it will start to track your new breathing rate. With the models prior to DreamStation, you had to keep hitting the "ramp" button repeatedly for several minutes until it had enough data to track your new breathing rate, which didn't exactly help the return to sleep!

So I took a few months of Cpap due to my aerophagia issues, I would say overall I slept better because of not waking bloated at 2am, but of course the sleep apnea didn't go away and still had so-so pretty resteless sleep

Finally got A ResMed ASV yesterday and I have questions

I used the default titration settings and Eson2 mask, I was only able to use it for 2 hours before bad aerophobia, but Oscar reports absoluttely no events and an AHI of zero ....
- First , does Oscar work with this machine, no events whatsoever, seems too good to be true Smile
- My breathing is low (10-12) and often dips slower during sleep (like down to , it always seemed to me that the dream station would think those where apnea and kicked in when maybe it was not needed, this machine does not seem to have that issue
- I see the pressure was all over the place, since aerophobia was an issue I'll to lower the max, at least as long as the AHI stays low
- Is that common to have long periods where everything is calmer and steady (1 to 1:30), is that deep sleep maybe ?

What does your Sleep Report say on the LCD screen?
Did you know you can get some information there? Check it and see if it also shows 0.0 AHI.

If it isn't showing anything but hours of use you have to go into the clinical menu setting and change
Essentials from "On" to "Plus" and then you can see the AHI and a bit of other summary data on the LCD screen under sleep report.
Please note the default parameters are 30 day numbers but you can change it to 1 day.
All explained in the provider manual. Did you get the clinical manual?
If not, go request it from here.
