Unfortunately, you got the wrong machine. The ones you should look out for are the Resmed Aircurve 10 Vauto and Philips Respironics BiPAP Auto (700 series, not 900 series). The machine you purchased in auto SV mode delivers a low, auto-adjusting exhale pressure (EPAP), and an adaptive variable inhale pressure (IPAP). The exhale pressure holds the airway patent, prevent obstructive apnea, while the inhale pressure varies, with the objective of maintaining a tidal volume target and a minimum respiration rate. This helps people with central apnea and other insufficient respiratory problems avoid central apnea, hypopnea and periodic breathing. These machines have a backup rate to maintain the respiration rate, even when the patient makes no spontaneous effort. If your breathing pauses, the machine will self-trigger IPAP pressure and will apply enough pressure to cause a breath and this pressure support may be as much as 15 cm H2O above exhale pressure depending on settings. So settings are very important. The machine has a CPAP mode, but that won't provide any therapeutic benefit over your auto CPAP.
The BiPAP Auto or Aircurve 10 Vauto, use a minimum EPAP to avoid obstructive apnea, and fixed pressure support during inhale to help make respiration easier, increase tidal volume and avoid hypopnea and flow limitation. These machines do not have a backup rate and rely on spontaneous breathing. Here is a thread by a member that recently started using a bilevel to replace his CPAP. This is what you want http://www.apneaboard.com/forums/Thread-...curve-auto FWIW, I think any Resmed machine (Resmed Airsense 10 Autoset CPAP) is superior to a Philips machine in comfort and efficacy.
Your BiPAP Auto SV is a very specialized machine, but it is also a very expensive machine, so you should be able to recover in resale what you put into it. The regular bilevels are half the price of the ASV new, and are generally less expensive used. Your 8000 hour machine is a bit on the high side of use, but I'm sure once you understand what this machine is, you won't have a problem selling it online. Meanwhile, check Offerup online marketplace for Resmed Vauto, I think you might be pleasantly surprised.
If, in spite of knowing that this is the wrong machine you want to pursue a setup of the Auto SV that will cause it to operate in a limited range to address some of the issues you raised in your other thread, I will give you some settings and tell you why they may or may not work. I just want you to know this machine is not intended to work with predominately obstructive sleep apnea.
