I have a question. I have seen this question asked on other forums and have yet to see an answer. A good electronics guy who's cracked a few open, would know.
RE: Respironcs Dreamstation.
Is the only difference between the CPAP, APAP, and BIPAP the firmware it's running?
Seems reasonable to me the most cost effective way to mass produce them.

FWIW I agree with you but I have never been able to prove it or find proof.
I think it's probably what all the brands do.

I think one of the forum members here has actually taken apart a S9 Escape and an S9 Elite and the guts are the same but of course one only reports hours used and the other is a full data machine.
I don't know if he has actually compared to an apap or bilevel though.

I haven't taken apart those dreamstations.

With the previous generation, they used different boards, and maybe different blowers.

Now, Resmed, with the S9 series, and presumably the air10 series, used the exact same hardware (I took apart a number of different S9 machines, all identical).

Not an escape, but a elite, autoset, vpap auto, vpap adapt (asv) and vpap tx (lab system). Never got my grubbies on an escape, admittedly, I didn't try too hard.

I couldn't remember what all you had taken apart.
Don't blame you for not trying too hard to find an Escape. :lol:
I had wondered about the higher end models though...good to know that all that fancy stuff with all the various sensors is in all of them.

You know, there's only two sensors in the machine.

A flow sensor that measures how fast the air is moving, and a pressure sensor at the outlet... everything else is done in the computer.

What I do find amusing is that they all have a squeaker in them... but only a few of them have an 'alarm' setting! and it's so wimpy that for the machines that *need* an alarm (ST-A, COPD), there's an extra module that bolts between the blower and humidifier.. that sucker is loud.
