Let's get clear about what we are calling things to avoid confusion.
BiPap....that's a Philips Respironics model name for a bilevel machine...bilevel just means 2 distinct pressures.
There are several different model bilevel machines...and each model might address a different problem or do something different.
Pressure support/PS is the difference between inhale and exhale.
ASV is a type of bilevel machine that can auto adjust as need for both obstructive apnea and central apnea.
It has a back up rate available so that if you don't breath enough then the back up rate will kick in and force you to breathe.
The PS will auto adjust as needed as well. This adjusting PS is what is needed to treat a central apnea and force you to breathe.
Regular bilevel machines...like the one I use (see link in my profile) don't have a back up rate and the PS is fixed and can't auto adjust. So a regular bilevel machine can't treat central apneas.
The bilevel S/T models do have a back up rate but they are totally fixed...no auto adjusting of anything.
They work more like a ventilator. Usually people have a really high PS because they have nothing but a lot of centrals to deal with. So you get a really high PS with every breath instead of only when you need it. Not much fun.
Pretty sure you won't like it.
