New & confused
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 like the PR? As I am new to this brand, I am confused on the terminology; i.e. differences between Bi-Flex vs. VAuto?

RE: New & confused
Here is ResMed's description: "The AirCurve 10 VAuto is an auto-adjusting bilevel machine that uses the comfort of both the AutoSet™ algorithm and Easy-Breathe waveform in its VAuto algorithm to treat obstructive sleep apnea patients who can benefit from greater pressure support.

The AirCurve 10 VAuto adjusts the baseline pressure to hold the airway open while maintaining a fixed pressure support."

Sooo,  it keeps the programmed SET pressures of 12/08, in VAuto, and will adjust Up/Down, depending on the events/positioning/etc? Thinking-about

Or maybe I’m not understanding the difference between Baseline Pressure, and Fixed Pressure?

It keeps the programmed pressure support of 4 but varies the max/min pressure as required.

OK, bear with me. I have OPS Grin

Programmed Pressure Support is the difference between IPAP & EPAP?

Machine is programmed for 12/08 but can, depending on need, cycle anywhere from 08/04 to 12/08?

Thank you for your patience!

I suspect the range over which the pressures cycle is a setting. I suggest you use the tab at the top of the page to get a clinical manual for your machine.

Thank you. I did that prior to posting on this forum. I am not a Respiratory Technician or Polysomnographic Technologist. I am a patient who was curious about how my former machine and this new device process and treat my OSA. I will, henceforth, look for these answers elsewhere.

I read that as 
Mode VAuto
Min EPAP = 8
Max IPAP = 12
PS = 4
This is effectively the same as fixed BiLevel "S" mode or spontaneous therapy.  The VAuto will vary pressures as needed but it must be given room to do so.  Such as 

Mode VAuto
Min EPAP = 8
Max IPAP = 20  The higher value allowed for IPAP allows for the machine's algorithms to modify pressures
PS = 4

PR allows for a variable PS which the VAuto does not.

VAuto is moth a machine model and the auto mode in the machine.
BiFlex is similar to Easybreath smoothing out the breathing pattern.

Baseline pressure is your EPAP/Exhale pressure, Fixed Pressure would apply to "S" or spontaneous Mode but "Fixed Pressure Support" as used in your quoted text (I added bold) means simply that the pressure support, the difference between EPAP/IPAP/Inhale/Exhale pressures is fixed, in this case to 4 (It can be manually altered.   Inhale pressure will always be 4 over the Exhale pressure but never over the Max IPAP pressure.

RE: New & confused
Thank you Fred for not quoting the manual Grin Your explanation was very clear.

I’ve been on this road 20+ years and discovered early on, that education is empowerment. Forums such as this, have given us so many options, in spite of Drs, therapists and insurance companies trying to turn OSA treatment into a private club.
