Thx!

PM sent.

CHICKEN!!!

I guessed it would be you, Slinky or Wulfman......
once again, you're keeping me honest.
As Snoredog(RIP) always said(paraphrased)
"Discussed in public is always better,
everyone learns and if you're wrong,
plenty to tell you you're wrong."

Here is the PM that I sent.

I have, for the past ~month, been walking in Resmed shoes.
S8 Autoset II
All other details about this machine aside,
it's quiet. Compared to the Mseries, there is no comparison.
It's quiet.
About this machine, I like:
compact style. small, easy to move, no Brick.
easy access to data and setup menus.
30min cool down cycle....don't know if that really helps,
but I like it.
EPR Easy-Breath is more comfortable than cflex.
-At first, I thought it was just my imagination, but after
using the Mseries for 2 nights, no doubt about it,
I'm getting better quality sleep w/the S8. I'm sleeping for
longer periods of time and deeper.
As far as data goes, I call it a draw between the two systems.
Although ResScan runs faster than EncorePro does.
I didn't think I was going to get the inverter for running on battery,
but after the last two nights on the Mseries, I think I'm going to invert.
I wrote the above review a few days ago.
I have only used the Resmed system for about a month.
I have used my Mseries two nights when the power was out,
and last weekend when camping.
For me, there is definitely a difference in the breathing
algorithum. The Resmed system seems to be more comfortable.
I like the idea that w/the inverter, I can have HH when
running on battery. That is not possible w/Mseries.
I really need the HH.

I'm going to continue to use the Resmed.
I will probably keep the Mseries that insc( actually me) paid for.
I'm going to sell my spare Mseries and get a spare Resmed.

You do the math.

Hope this helpful.

Thanks Carbonman! I'm glad you posted this, because for some strange reason the PM hasn't shown up. BTW, how do your numbers compare (on average) between the two machines? I know about the rule of thumb re cutting the ResMed HI in half, but since I have mostly hypops, I don't know if that would hold true for me....

No need for an inverter, which converts DC to AC.

The ResMed have a jack for DC input just above where the AC cord attaches. You can attach a 12 battery there. You must be sure to have the polarity correct. You probably could make an adapter to connect the battery for your M Series to the S8.

Do not connect your machine to AC and DC sources at the same time.

Actually the 'newest' M series HH is 12vdc which means that it will in fact run on battery power. I am not sure that anyone else does that yet.

CM what pressure are you at?

Did you feel like you missed the humidifier? What was the temperature and humidity at night?

I wondered about that. The manual for the Intellipap Auto says something to the effect that you can plug in both AC and DC at the same time, and if the power fails, it will automatically switch over. I guess that's not the case with the ResMed S8 IIs. Still, I didn't want to fry my machine finding out!

BTW, the ResMeds may not have the big power brick for AC, but the DC converter box is huge. Too bad ResMed reversed the polarity.

...just proving Snoerdog(RIP) correct again....
learning and being told in a matter of minutes.

I love this place.

My numbers are higher.
I'm not going to worry about it.
I sleep better and feel better.

I'll be checking that out. Thanks!

...and you......always throwing a wrench into the works.

I be very comfy at 11.6cm( H2O implied).

I can tell immediately if the HH is not on.....
...but, only low HH. If I turn it up to high, my numbers go crazy.

SInce there is no convention for wiring of the sort of low voltage DC "barrel" connectors as used on most CPAP machines, its not a matter of "reversing" anything.

WIth low voltage DC power you always need to check how the equipment manufacturer has wired their input jack

Thanks for the correction, Bill. This is what the DME told me. Bad on me....
