Respironics Auto BiPap question:
The Flex Setting allows you to adjust the level of air pressure relief that the patient feels when he/she exhales during therapy. It is recommeded that you start with the minimum setting of 1, which provides the least relief. Two and three progressively reflect increase pressure relief.
Rise Time is the time it takes for the device to change from EPAP to IPAP.
This is closely copied from the Respironics Provider's Manual.
So a flex setting of 3 provides the most relief? Why set it with 1? If a 3 allows it to change faster, wouldn't that help alleviate the "bumping into the machine" thing I talked about? Put another way, I was set up with a "one"....I change it to a 3....won't it change from EPAP to IPAP FASTER? Meaning when I inhale I don't "hit the wall"???

Installing Software is like pushing a rope uphill.
I have Encore Pro 1.8.65 but could not find it listed

I LOVE the SV.

The bi-flex setting of 1, 2, or 3 on Respironics bi-level machines has nothing to do with how fast the machine changes up to the higher inhaling pressure (IPAP).
Bi-Flex also has nothing to do with the inhalation pressure or with how long the inhalation pressure lasts.
Bi-flex is nothing more than some icing on the cake...a little bit more drop in pressure at the very beginning of an exhalation.
The EPAP (exhalation pressure) is already the lower of the two pressures in a BiPAP machine. Bi-flex makes the START of the exhalation pressure a tad lower than the remainder of the already low EPAP pressure setting. Bi-flex simply makes the beginning of an exhalation feel a little softer (with a little less pressure) than the remainder of the exhalation feels. Similar to the way C-Flex works in other Respironics machines...working just on the first part of the exhalation.
Bi-Flex setting of "1" gives a little bit of drop at the beginning of an exhalation. "2" gives a bit more drop (still just at the beginning of the exhalation.) "3" gives the most drop.
The "rise time", is what gets a bi-level machine to switch rapidly or slowly to the full inhale pressure when you start to inhale. Some people like for the machine to switch immediately up to the higher pressure the instant they start to inhale...so they set the rise time as short (as low a time) as possible. Others like for the inhalation pressure (IPAP) to work its way up more gradually, so they set the rise time for as long as possible.
Neither of the settings -- for bi-flex or for rise time -- affect how long the IPAP pressure lasts while you inhale. I wonder if IPAP stopping too soon is what you mean by hitting the wall? Feeling like your inhalation is being cut off too soon. That's how it felt to me -- like hitting a wall -- when I was in the midst of taking an extra long breath and the IPAP pressure stopped and the lower EPAP pressure began...while I was still inhaling.
ResMed's bi-level machines have an "IPAP Max" setting that can be adjusted (I set the IPAP Max for as long as possible on the ResMed VPAP III) but even with that extra setting on ResMed bi-levels, an inhalation can still feel cut off if you take an occasional very, very long breath.
