Question Re: ResMed S9 VPAP Adapt

[ThomasMcKean]

Hi guys...

Been forever since I have posted here. it must mean things are going well for me CPAP wise. And they still are. This is just a question...

My brother in law's mother died a while and he gave me her machine, an S9 VPAP Adapt. Now if I remember correctly, this gizmo is more for Central than Obstructive. And I think I remember reading somewhere that is is dangerous for Obstructive and should only be used for Central?

To recap, I have Obstructive, I was measured at a 51 AHI (not overweight, but I did wake up one morning unable to breathe. Damn near killed me), and they also determined my setting is 12. I have a Philips, the model before the bluetooth, it has a heated tube which never seems to work, and I also have the model before that, with no heated tube, and I think, somewhere in the deepest recesses of the closet, I even have an S8, the most god awful ugliest CPAP ever made, though in its defense, I have to say that the humidity on it works better than any of the others.

Now in tinkering with the VPAP Adapt, I see there is a regular CPAP mode. But when I try that, I do not see any EPR settings. So my question is, does the VPAP Adapt for some reason not have the EPR, or is it hidden away somewhere in the menus where I just haven't found it?

Also, is this thing safe to use in ASV mode if you are Obstructive? It seems just a bit nicer than the one I have, can I use this safely or do I need to write it off? I have no problem adandoning this if it isn't for me, I am just wondering...?

It doesn't have EPR in CPAP mode.

It doesn't have EPR called EPR in the other mode but it has something called pressure support which works like EPR but we have to go about the settings sort of backwards from CPAP and EPR.

Tell me the other modes available....is it one or two....ASV mode or Auto ASV mode or both?
Look on the sticker for the model number is it 36007 or 36037?

Get me that information and exactly what all your settings are on your current machine and I can get you some settings very close to what you are using now.
Yes, this machine is used for central apneas but it won't hurt you and we can dumb it down so that it functions like a regular cpap machine.
I have used both the 36007 and 36037 myself...and I don't have central apneas either.... we can get you real close to matching what you are using now and any minor differences won't hurt you.

The machine won't do what it does to treat centrals if you don't have any centrals anyway and until then it treats OSA pretty much like any other auto adjusting bilevel machine.

[ThomasMcKean]

It is a model 36007, which probably means it does not have the ASVauto because I did not see that option.

I been looking into this more, apparently VPAP is another name for BI-PAP?

And if I am understanding correctly, I think I know the settings. I am currently using an APAP in CPAP mode set to 12 with a C-FLEX set to 2. So if I am getting this right, I would set Max PS to 12 and the EPAP setting to 10. Yes?

[Pugsy]

No...Way too much PS available unless you want to let it treat centrals. What is the minimum PS? Seems like it was 3 but I can't remember for sure and don't have that manual handy.

Do you have a minimum PS and a maximum PS available and what is the lowest number you can get in the PS setting?

The 36007 won't auto adjust the EPAP...the only part that will auto adjust is PS to give a person an IPAP that roams as PS roams.

EPAP (exhale) plus PS equals IPAP on a bilevel.

On the regular cpap/apap machine in fixed cpap mode....the fixed setting is the IPAP and the exhale relief comes off of IPAP (inhale)

It's been a while since I used a 36007 machine....so that you can make us of PS to give you exhale relief tell me what settings you have to choose from. I have forgotten

EPAP set to 10 and PS set to 2 both minimum and max (if it will do that) will make the machine function like cpap at 12 with an approx 2 cm drop during exhale. Respironics machine don't quite do a per cm drop with their Flex relief so that setting of 2 Flex probably gives you about a 1.5 cm drop during exhale.

PS minimum and maximum...that's how the machine deals with the centrals. When a central happens the machine kicks in and rapidly increases the PS. Otherwise PS hangs out around the minimum setting most of the time.

You want a low minimum PS....and it won't hurt you to let the machine deal with the centrals but you might not like what it does because it might take that 10 cm EPAP and push you to 20 or 24 IPAP in about 5 seconds.

[ThomasMcKean]

I can do EPAP 10 but lowest is will go for others is MIN PS 3 and MAX PS 8.

[Pugsy]

We can get close.

EPAP 10
minimum PS 3 (then the lowest PS it will go to which maybe be 4 or 5...don't think it will let you do PS max of 3.

This will give you 10 exhale and 13 inhale at the beginning of the night.
And the PS will vary very little and IPAP will run between 13 and 14.

Your old machine you were doing 12 inhale and approx 10 exhale.

I don't think you will need 10 EPAP with this machine though. I needed much less EPAP with it than I did with my Respironics machine.
I would try EPAP 9
Minimum PS of 3
that will give you 12 IPAP like you have been using.
Use whatever max PS you want to use but and you could use 8 and it won't hurt you because it won't be used unless you have a central.
But I suggest being conservative for now and using the lowest PS max it will let you set.

It's not exactly what you have been using but it is very close and should be extremely comfortable to you.

[ThomasMcKean]

Thank you I will try that.
