May Have Bought the Wrong ASV Machine?

New poster here. Have been using an old Respironics BiPAP S machine for years. It recently died. Have purchased a second hand Repironics BiPAP auto SV unit to replace it. My research on that particular model indicates its primarily intended to treat CSA. I* have OSA. How do I progtam it for my use? Can it be programmed for my use?

I have a Resmed Mirage Quattro mask. The unit has the humidifier but that is missing the cord to plug into the wall. I have a Fisher-Paykel remote humidifier I was using with my old machine. I can use that until I get a cord.

Here is a link to the machine I have:
https://www.cpap.com/productpage/remsta ... chine.html

In checking that link, I see it says "Advanced" Don't think mine is the advanced version. Ok,m after a little more checking, mine is not the advanced model.

This machine is very complex, the old one was dead simple. Two dials on nthe back to set the pressures (which I never had to adjust) and a switch on the front. Easy peasy...

I am going to need some help setting this machine for my use. I don't have insurance and very little money so new sleep studies and professional adjustments are out. Well, out unless absoloutely neccessary. I have a car I can sell to fund professional help if it comes to that.

In the meantime, I am reading. As my old machine worked fine for me, I never looked online for any forums. Now I see these machines have gotten very complicated over the years and I am going to need to learn about them. This data storage capability is interesting. But first: I need to get it working for me or replace it.

What were your pressure settings on the BiPap S?
I assume you have some sort of manual since you mention the complexity of the machine..which manual do you have the user manual or the provider manual?
You did buy a fancier machine but I believe it can be dumbed down a bit so it will work for you.
We need to get JohnBFisher to offer ideas how. Can you edit your subject title and add ASV in between Wrong and Machine?
Do you have the software and card reader for this machine?

Dumbed down. Thats the ticket!

Ok, I have a copy of the user's manual. Seems complete. My pressures were 15 and 9. I don't have a smart card for it, have no software.

Sorry if my questions are basic, I have not had much time yet to research this unit. I just got it home yesterday. Also, can't tell you much about my apnea as I have not had any problems with the old unit (until now!) and no real reason to delve into my teatment. Doc prescribed the machine and settings and all has been well since then. At least as far as I know.

I am reading about OSA (my problem) Central sleep apnea (not my problem as fas as I know) Hypoxia Ramp BiFlex AHI CGI GTO XR7 Lots to catch up on in a short time.

Okay, give me a few minutes to locate the clinical/provider manual which will show you how to access the clinical setup menu. I don't remember if that machine has a plain BiPap mode or not. It may.
I will send you a private message in a few minutes with a link for the clinical manual along with some information about how to use the software if you wish to.
I sent JohnBFisher a note and asked him to stop by in your thread here to help you with the settings.
He is very familiar with this particular machine. While I have a Respironics BiPap...it is a newer model of what you used to use so I don't know what settings are available in this ASV machine but I think we can dumb it down to work for you...It might even have a dumbed down mode available. I need to go look at the manual.

Hi WW3. I'm not sure if JohnBFisher is on vacation. So I'll chime in until John has a chance to post... See the manual section that describes the button-pressing sequence, so you can change and view settings in CLINICIAN MODE. I understand you ran at 15cm/9cm in spontaneous mode. Those values translate to these settings on the original BiPAP Auto SV model----the original version that is NOT the Enhanced model:

EPAP= 9
Min IPAP= 15
Max IPAP= 15
Rate= off (this is spontaneous mode to match your previous machine)

Set the ramp length and ramp start-pressure according to your preference. The default settings for the remaining parameters should be fine. Those default settings are the values shown in the manual. I'd also suggest calling a sleep lab and explaining your situation with the new machine. There's a good chance they'd be willing to verify the machine's settings and functionality at no cost. Good luck!

Thanks SWS...I hadn't seen you in a while and didn't think to ask you. My bad. Sorry.

On the contrary, Pugsy. That was your usual "good". And John's the perfect go-to person for ASV... and countless other things too.

The settings that ~ SWS provided appear to be what the doctor ordered. Unfortunately, I have problems with my internet access, so I can not do the research that I normally do.

Thanks folks, I really appreciate the help. Perhaps tonight I'll get a decent night's sleep.

BTW< what do I need to hook up the humidifier? It has a short two-prong, female pigtail. Seems there should be an extension that would have a regular plug on the other end for plugging into a wall receptacle.

Not sure but I think that little 2 prong thing plugs into the machine somewhere in the back. I think it receives power via the connections to the main blower unit and not via direct cord to electric socket.
Take a look at the manual to see if you can spot where it goes.
If you can't...need to wait till someone who uses the Legacy tank series machine to tell you. I haven't seen this model.
I did use a M series model machine and the humidifier for it plug into the blower unit.

Yep Pugsy, you are right. I now have the humidifier hooked up.

My settings (as of now) according to the display on the unit:


Epap-9.0
Ipapmin-15.0
Ipapmax-15.0
BPM-auto
rise time-1
ramp-0:20
ramp start-5.0
apnea-40
patient-0
MinVent-0.0
Light-1
Hours-4.6

Hi, WWW3. I'll offer comments about the settings I highlighted in red text...

BPM-auto- You now have the machine set with a backup rate for central apneas. Changing this setting to "0" converts your modality from BiPAP S/T to BiPAP S instead (BiPAP S rather than BiPAP S/T is what you mentioned your previous machine was)

rise time-1- This is the amount of time (in tenths of seconds) it will take your machine to transition from EPAP to IPAP. A setting of 1 is the quickest, steepest transition possible. Most people can't tolerate an EPAP-to-IPAP transition that quick. However, if that's what you ran on the previous BiPAP S machine, then you're good. Otherwise you might need to raise this value to make IPAP rise time more comfortable.

apnea-40- The machine will wake you with an audible alarm if it scores an apnea at least 40-seconds in length. That's a necessary safety feature for some patients. Many patients disable this alarm by turning it off. Turning the alarm off matches your previous BiPAP S machine, which doesn't have this apnea-length alarm.

patient-0- This is a "patient disconnect alarm". And a "0" setting means the alarm is "off" (matching your BiPAP S machine, which didn't have that alarm).

MinVent-0.0- Again, a "0" setting disables this "low minute ventilation" audible alarm. Since your BiPAP S didn't have this alarm, setting it to "0" to disable the alarm matches your previous setup.

In summary, I'd suggest reviewing/reconsidering whether the "BPM auto" and "rise time" settings are what you really want.

Ok, I have reset BPM to off (there is no actual "0" setting).

Reset Rise Time to 5.

Apnea alarm sounds like a good idea. 40 seconds seems a long time. Should it perhaps be set for a shorter time?

Will research what "MinVent" really means. In the meantime, should that be enabled?

BTW, WW3 means World War 3. As in: "he snores like WW3".

That sounds more comfortable. You can experiment with this parameter while lying awake and rested. It's primarily a comfort feature, although some doctors will use quicker rise times to help mechanically offload the work of breathing (WOB).

WW3 wrote: Apnea alarm sounds like a good idea. 40 seconds seems a long time. Should it perhaps be set for a shorter time?

That's up to you. Set it according to what offers you peace of mind. You were formerly using BiPAP S, which didn't have this alarm. Patients who qualify for BiPAP S mode don't need this alarm. Patients with central apnea problems sometimes require this safety alarm.

WW3 wrote: Will research what "MinVent" really means. In the meantime, should that be enabled?

Minute Ventilation speaks of air volume you breathe in a 60-second time frame. This is another alarm that patients who qualify for BiPAP S don't need. This alarm is best suited for patients with hypoventilation disorders.
