Thanks for all the informative replies.


Sir NodinOff, do your experiences with Resmed AVP include the very lastest model as well? I understand they made some important changes which have improved the model like
auto expiration level.

I have the one year earlier model ResMed Adapt 36007. The only difference that I've heard of is what you mentioned, an auto EPAP feature, not an insignificant addition. Given that, I've known what my most efficient/comfortable EPAP level is for two years, therefore I don't need that feature (my EPAP settings are also confirmed by my PR machine, which does have the auto EPAP feature).

Ok so only that is new. Hmm.

Why does Resmed seem to claim rise time is adjustable then here?

Reading the spec sheet it's not clear to me if that feature is user programmable or if it's part of the algorithm. Maybe you should ask one of the folk who has that model. It appears the only way to be sure is to look for rise time settings in the clinician's menu.
LATER EDIT: Here's something I just learned about, a cautionary addendum, so to speak. I'm not a doctor. Be sure to talk to your sleep doctor before changing your rise time and get a sign-off from him/her. Setting your rise time too long can compromise your CO2/O2 exchange efficiency and could be dangerous. This is not a feature you want to go dial whinging.

There is no rise time adjustment in the ResMed 36037 Auto ASV in either auto or straight ASV.

Thanks for that Squid.

So machines like the DS1160TS are beyond the spec of AVS? Certainly seems more expensive via some suppliers. Could the Philips line be more confusing if they tried? Hah.

Thanks Squid for clearing that up. Anybody else wanting to change their rise time should read the last part of my previous reply for a cautionary note and note graphic below:

Trying a 950P. Going to need to use ramp to help me get used to quick feeling breathing alright! I see that auto on works but no auto off? I found that handy on Resmed when taking a small break.

The 750 had separately configurable Auto On and Auto Off. So does the 960.
I can't imagine that the 950 eliminated that feature.

Its my understanding that ResMed implemented this feature with Auto On and Auto Off couple together and not separately configurable.

In settings there is auto on which is on, then patient and apnea alarms which are set to 0. See nothing else mentioning it.

Edit:

One other thing that concerns me on this model/fw version, there is no overall 'mode' setting that I can see. So lets say I said ok I want it to be in manual CPAP mode or APAP then on this machine I'm SOL. The machine also never seems to turn off unless you yank the power cord, there is no idle time out period (not sure if resmed has this exactly either though, but there is a power switch).

Had a pretty poor night last night which was also 'helped' by having a bout of insomnia that sometimes occurs even though +16 hour day etc. Will solider on
though!

Hey guys, been a few days with machine now.

Here is the manual which matches the settings I see:

http://www.healthcare.philips.com/pwc_h ... manual.pdf

What sticks out most though is that there is no mode selection? So this machine can do ASV mode only, no apap, no cpap, no bipap. Is this just this older model or are the newer ones the same, could anyone post a manual for the new ones that shows these settings? Maybe it is also a regional thing.

Secondly I'd appreciate any ASV tips you might have. First night I got 3-4 hours, last night I am not even sure I got 30 minutes of sleep. The hybrid mask felt like it was inflating too much with the pressure changes, and of course I find that the machine starts to assist my breathing right when I'm about to doze off sometimes which wakes me up. I then swapped that mask for a new wisp which I started to nod off in but was having mouth/lip evacuation so went for tape. But by then it was already morning and I was too awake to get to sleep any more anyway.

I think when it tried to blow a sudden gust of air down me it is going into my stomach a bit as well which I've never experienced before, could hear some rumbling after each event!

EDIT: Some of my post repeats above post... yep I must be tired

To see the Auto On and Auto Off settings, you need to be in the Clinician menu.
I just checked my copy of the 950 Providers manual and this feature is there.

To get the CPAP and BiPap modes, you need to change the settings to simulate the mode you want.
The ASV machines don't have those settings as selectable items.
Pugsy or JohnBFisher would be better references on how to make those setting than I.

It sounds as if you have the Back Up Rate set to Auto and you have transitional centrals that the machine is reacting to.
The first thing to try is the Ramp setting to see if you can get past them that way.
Otherwise, you might try setting the Back Up Rate to 10 to see if that helps any to get past them.
What you are experiencing it the speed at which the ASV machine reacts to breathing irregularities - very much different that either the Auto CPAP or Auto BiPap. It will take some time to get used to the difference. I have occasions in which my ASV will switch between "normal" mode and ventilator mode and back during three consecutive breaths so it is going from 19/15 to 25/10 and back to 19/15 cm H2O. That can be disconcerting if it occurs while you are drifting off.

That manual I linked says user manual, yet it seems to have all the settings a clinician would adjust anyway? All the pressure settings are there. Is there yet another secret menu hidden away though, I did have to use a button combo to access all the options so it certainly seems to be clinician. [yep checked, those are all the options any system one machine has, so no auto off] Does your model also power itself off or do you have to unplug the power lead?

I see, so it isn't a simple X mode setting.

Yes I need to try ramp more, I did on first night a few times and one of the attempts worked. Last night I tried sleeping without ramp first but later tried it without managing to get off. It just reminds me of years ago when I used to have manual cpap and always used to ramp, seems rather antiquated! But if it helps it helps.

Nope, the Clinician manual has additional settings explained.
Ramp is useful during the time you are getting used to the ASV but, over time, you should try to get to not using Ramp.
You can get a copy of the Clinician manual from the ApneaBoard web site.

Ok thanks for the tip. Looked at both manuals now.

The "PR System One BiPAP AutoSV Advanced" manual is the nicely formatted clinician manual and mirrors my machine. No auto off is mentioned.

The "PR System One BiPAP AutoSV" manual is the messy scanned copy and does mention auto off. They must be different models.

Looked at bottom of machine and was made in March 2011.
