Look at Mfgr's Web Site for a Start

There are lots of knowledgable people on this and other forums - but
you might try the major machine mfgr's web pages.

I know Respironics explains BiFlex and other features they have
http://www.respironics.com
and ResMed is their Australian competitor at http://www.resmed.com
or http://www.resmed.co.au

There used to be a good graphic on the Respironics web page that showed
just what type of waveforms a standard CPAP a BiPAP and one using
CFlex looked like that went a long way at helping the understanding.

Bipap gives you two different pressures, one for inhale one for exhale. The two pressures can be several cm different. My machine allows from 2 cm to 8 cm difference.

Auto Bipap does the above PLUS it allows a range of pressures during the night. It senses your pressure needs based and changes the inhale and exhale pressure during the night as your needs change. Like an auto cpap, this allows you to spend more of the time at lower pressures, but allows the machine to increase pressure when you need it most.

BiFlex is the BIPAP equivalent of CFlex, but a bit more complicated. It smooths the transition from inhale to exhale pressure, which makes therapy more comfortable.

All of these features are more valuable for patients with higher pressure needs.

Other manufacturers make bilevel machines, but the terms Bipap and Biflex belong to Respironics. It is my understanding that only Respironics makes an automatic bilevel machine.

just to add what Moogy said:

Bipap is comparable to a straight cpap machine (set pressure for IPAP and EPAP).

Bipap Auto is like an autopap, it finds your ideal pressure for you. Machines with BiFlex are like cpap machines with Cflex (in fact cflex was derived from biflex, a patented feature found only on Respironics machines).

Here is the new M series Bipap Auto:

The Bipap S/T models are if you have Cheyne-Stokes breathing. Think it means synchronous/timed. With CS, you stop breathing, the machine will try and assist you with breathing, then it has a timed mode. This is the most complicated of the Bipap machines, also the most expensive.
