Hello, I am new to this forum, but started CPAP therapy in 1997. Recently purchased a ResMed AirCurve 10 VAuto w/humidity; 2 nights in, so far so good. My previous machine was a PR System One REMStar 60 BiPAP Auto w/Bi-Flex; same pressures.

ResMed machine is set to VAuto, 12/08 PS 4. My question is, does the ResMed machine vary my pressures, as needed, like the PR? I am new to this brand, and am confused on the terminology; i.e. differences between Bi-Flex vs. VAuto?

BiFlex is Respironics exhale relief adding on top of the relief that using PS offers.
ResMed bilevel machines don't really have any additional exhale relief similar to BiFlex that the patient can alter that is more of an automatic nature.

Tell me exactly what you see as the settings available to you in VAuto mode

If max IPAP is 12...the machine won't auto adjust so all you will get is 8 exhale and 12 inhale.
Max IPAP needs to be higher for the machine to go higher if it wants to go higher in VAuto mode.

Max IPAP 12
Min EPAP 8
PS 4
Vauto mode

The isn't going to vary the pressures at all throughout the night at these settings.
Inhale is 12
Exhale is 8
and essentially these settings has made the auto adjusting mode into a fixed bilevel mode.

It can't auto adjust because there's no where for it to go.

If you want it to auto adjust your max IPAP setting has to be higher than 12. Most people would just set it to 20 or 25 and let the machine go where it thinks it needs to go.

When it increases the pressure the difference between inhale and exhale would be 4 cm..that's what PS is and does.
If it doesn't need to increase the pressure then it won't increase the pressure.
