Google can be your best friend.

You are welcome to go digging for patent dates but ResMed got the first one.

I did before I posted but apparently Google doesn't know what you do.

So instead of saying "wrong" like some people here do I thought I'd ask.

Sorry to trouble you.

This is what I found
https://patents.justia.com/inventor/gilbert-d-saul
No mention that Inventor Dr. Gilbert D. Saul was ever associated with resmed.

Well...I don't know what to tell you but that link above was from my own Google search and either the first one or second one after the usual ad hits. I use Google for web searches exclusively.

Searching using Google or whatever search engines....a lot depends on the question asked. I probably used a little different words in my search.

No problem...so now you know and so do other people.

All very interesting for the unenlightened like myself , there is so much to learn and take in!

In my research I stumbled across a Sleep Titration Guide to ASV which suggests an ASV Auto Protocol (by lab support 24/7).
Apparently there is an ASV Auto default setting, which to the unexperienced like myself, is fascinating.

It sates that there are only 4 parameters to set, which we all know about, the default being:
Min EPAP 4cm H2O
Max EPAP 15cm H2O
Min PS 3cm H2O
Max PS 15cm H2O
Ramp OFF

I found that intriguing and while my machine and I are becoming better acquainted and more intimate, I plan to set my machine to the above, but set EPAP Min to 6 as opposed to 4 to see how I get on.
Since my AHI is now Zero, I think it is worth a go for a few nights, so I have a starting point and take it from there.

Maybe someone else has already been there and done that, but I have not found anyone that has done that.
Any input always greatly appreciated.

You might remember that setting your minEPAP to 6 was what started this thread.

I don't understand why you want to mess up success.

Hi Palerider,

Thank you for your response.
To answer your question, things just do not feel right and it is for this reason that I want to see if I can fine tune it a bit.
I know I need to give myself time to get used to the new machine, but with the Philips I felt great after day one.

Last night I must say that I had a better night having put the machine mostly on the default settings.
My oxygen saturation levels were also much better averaging 96% lowest 92% which was also a huge improvement to the 88% that I was regularly getting on my previous settings. Ahi 0.21 so really happy with that.

It feels closer to my old machine, more subtle.
Question: I wonder if the Resmed Aircurve 10 ASV Auto does not go into 'ventilation mode' if the person does not need it?

With the Philips I always felt that it was in the background and only ramped things up if I needed it.
Most nights, I had to check to see if I had switched my machine on, it always felt so natural.
Trying to get that from the Resmed, if at all possible.

Does the Resmed do the same ie allow me to breathe myself or does it always ventilate the person 100 percent of the time even when it is not necessary i.e. when the person does not need it at certain times in the night, does the machine back off?

Not sure if there is anybody out there that would know the answer to that, but I will keep searching on the internet, in the meantime, to see if I can find out.

Thank you again for your input.

All you have to do is look at the mask pressure data in Oscar to see your answer.

When "you don't need it" it runs at the minimum set PS, when your breathing effort drops, it increases the PS on a breath by breath basis, as needed to maintain your TV at 85% (iirc) of your rolling average.

Here goes my first attempt at a screen shot!
Is this what you meant pale rider? Many thanks.

Hi Palerider
Not too sure where to look on the chart to see if the pressure support kicked in or not.
Thanks Pugsy for the tip on doing a screen shot !

look at the "mask pressure" graph of what you posted. it's the one that is colored blue. see how it jumps up to 25? now look at the "events graph" at the very top. see how your pressure increased in response to that UA?

that's the machine doing it's job.

Got it in one... and in other places where the PS increased and prevented apneas.

Thank you, the Mask pressure is the easy bit, I see that written clearly on the chart, but I do not see the pressure support written anywhere.
Let me see if I have understood this correctly is it because the pressure has gone up to 20 that the pressure going up is the 'pressure support' Is that what is mean by pressure support?
I am a bit baffled by the whole thing at the moment

yup. this is what it means. just formulated the sentence a different way.

don't worry about being baffled. no one was born knowing all of this. and always, ALWAYS, ask questions so that you can learn.

in a matter of months, you'll know everything you need to know about all of this!

EPAP: The pressure when you're exhaling, or between breaths, this is where oxygenation happens, so if your SpO2 is low, or you have apneas, hypopneas, flow limitations and snoring, increase the EPAP.

IPAP: The pressure that it rises to when you're inhaling, this is where ventilation happens, and on an ASV is what forces air into you when your respiratory effort decreases.

PS: IPAP - EPAP, simply the difference in the two.
