I don't know about the Resmed VPAPs, but on the PR System One BiPAPs, the way the ramp works is this:rested gal wrote:As far as I know...Madalot wrote:It's too bad that the machine won't allow the Ramp to start any higher than the EPAP (can we say 'stupid'???). If I could leave the EPAP around 8, but get the Ramp to start around 12-13 and gradually Ramp up to 17, it just might work. But no, this machine won't allow me to do that.
I don't think any bilevel machine will allow a Ramp start pressure to be set higher than EPAP (the lower of the two pressure settings...EPAP/IPAP.)
Likewise with autopaps -- I don't think a Ramp start pressure can be set higher than the minimum pressure setting in the min/max pressures range.
- Starting Ramp EPAP can be set anywhere between 4cm and strictly LOWER than the EPAP (in standard Bi-level mode) or min EPAP (in Auto BiPAP mode), and
- Starting Ramp IPAP = Starting Ramp EPAP + 2cm in all cases
But alas, for some silly reason, the Trilogy doesn't seem to be set up in the same way even though it is a Resprionics machine, at least as near as I can tell from what Maddie says about the ramp. So to Maddie, when your starting ramp EPAP is set to 9cm, are you sure the starting ramp IPAP is also set at 9cm? Or might IPAP start at 11cm? Maybe you could check this during the daytime by watching the actual pressures when you first mask up and turn the ramp on?
