I know for certain that increasing pressure triggered 3x the number of central apneas during my titration measurements, yet I may still have residual obstructive apneas to address that will require increased pressure. I'm doing much better than my 50-60 AHI per hour before CPAP, but would love to get it below 10 on average as a mid-term goal.
Some doctors seem not very concerned about a moderate amount of pressure-induced central apneas which may show up during an initial titration, because, as our system becomes accustomed to breathing under pressure, these pressure-induced central events tend to reduce and disappear, during the first few weeks or months of therapy.
Hopefully, that will be true in your case, too.
This may be why insurance companies sometimes require a trial with a standard xPAP or standard bi-level machine without a backup rate, before approving an ASV bi-level titration and an ASV machine for patients who may have lots of centrals during a titration.
