I also messed up when I edited my post on the other page, resulting in a second version that looks like an exact repeat, but isn't. However I think you were going by the second version, so that's fine.
Oh, by the way, I didn't say "instaneous"...I said "almost instanteous". A minor distinction, but one that does make a subtle difference. And I know you like subtlety, you naughty boy, you! "Naughty" is such a fun word, isn't it?
The absolute best place? Well, perhaps you might contact the engineers at the major cpap manufacturers. If they'd talk with you. Ask them about PB's choice to use a separate sensor line running up through the main air hose, and the choice by ResMed, Respironics (and most others) to not use a separate sensor line.dsm wrote: the absolute best place to sense that [pressure] is at the mask end - just as PB do. That is not a trivial flip of a coin design decision (ask yourself which end of the tube has the OSA, the user or the machine).
I agree that it's not a trivial flip of a coin design decision, so ask yourself why two major companies as heavily into designing cpap machines as ResMed and Respironics are, chose to design theirs with no separate sensor line running up through the main air hose. Or why another major company, Puritan Bennett, chose to use a separate line. Perhaps it's because the machines are designed to effectively sense and respond to whatever they need to sense, either way?
I decided to use the word "whatever" -- sounds techie enough to me, even if not in engineer-ese.
