I think that the reason that there is a limited number of posted recommendations on here that would "suggest" which machine is best for you to treat combined central and obstructive apneas is because many of use feel that the first line of defense against any type of sleep disorder is a good comprensive sleep study in a controled enviornment and followed up by a board certified sleep physician knowledgeable and experienced in sleep disorders. Self dianosis and self prescribed CPAP therapy can do more damage then good.
Your post was void of any of your background knowledge or use of a CPAP even though you have some knowledge of your preference. Perhaps more personal info would encourage more responses.
Yesterday is history; Tomorrow is a mystery; Today is a gift; Thats why its called "The Present".
Central or mixed apnea is complicated.
Usually, a constant CPAP pressure won't fix it. In some people, a higher CPAP pressure causes central apneas.
In many people, as pressure goes up, obstructive apneas go down and centrals increase. Sometimes, you can find a good compromise pressure.
Central or mixed apena is one of the reasons it's absolutely critical to have a fully data capable machine for all patients. You may develop central or mixed apnea after starting CPAP and need to monitor for it.
Auto CPAP (APAP) doesn't necessarily help with central apnea. They may make it worse if the pressure range is set where the pressure can drift up to the point where you start having centrals. The manufacturers try to design their machines to detect centrals and not increase pressure if you start having them.
APAP only changes pressure slowly, it doesn't try to match your breaths.
Bilevel uses a different pressure on inhale and exhale. Also called BiPAP or VPAP. Sometimes this helps central apneas, sometimes it doesn't help or hurts.
A step above bilevel is a "Timed" or T mode bilevel machine that will attempt to start your breathing with higher pressure if you don't inhale after a certain time.
The next step up is an ASV (Adaptive Servo Ventilator) bilevel machine which does a much more complicated process and does go into more of a "force you to breathe" mode.
Throw in the complicating factor of Auto pressure adjustment on bilevels. Many CPAP/APAP machines have exhale relief/Flex/EPR, which is sort of like low level bilevel.

If it's midnight and a DME tells you it's dark outside, go and check it yourself.
I Have the same as you and use the Philips Respironics System One BiPAP autoSV Advanced (951P)
its a great machine fully data compatible my AHIApnea / Hypopnea Index is at 1.64 and most importantly feeling great again been using it around 3 weeks
First off... I'd like to sincerely THANK EVERYONE for taking the time to reply to my initial post.
I'm from Ontario, Canada and did do a sleep study in a sleep lab - that's how I found out that I have both OSA and CSA (honestly didn't even know CSA existed until the sleep doctor told me that my case is complicated because most people he's seen have either OSA or CSA but I have both. So @ Ugly, you're not alone my friend.
I'm currently borrowing a S9 Autoset with settings of 6min to 15max and and found that I wake up when the pressure gets to about 14 cmH20. The funny thing is I feel the same using (or not using) a machine. Although with my old machine (Resmed S8 Compact) I can't tolerate the pressure of 9 because that constant force gives me stomach & lung pain so I wasn't really using it.
