Are central apneas more common at higher pressures?

Are CSA events more common at higher pressures? (Perhaps due to more frequent arousals?)

I'm thinking of using an MAD device simultaneously with CPAP. I assume that this would allow me to reduce the pressure, and I'm wondering if the reduced pressure would also mean a decrease in the CSA events that I get. Currently with CPAP all my events are CSA now.

Sometimes true for some. Not all.

I did that for a few years. Helped me learn to keep my mouth shut with nasal pillows.

I did not find that to be so. But hey I'm just one opinionated guy on the Internet.

reduced pressure would also mean a decrease in the CSA events that I get.

Lowering overall combined AHI is a worthy goal, but using enough pressure to prevent obstruction should remain priority, since obstruction can be particularly damaging and many home-machine-reported "centrals" might have rightly been ignored and unscored in an NPSG.

I wish you success in finding the best pressure(s) that give you the lowest overall AHI over time and the best possible subjective sleep quality.

As mentioned, higher pressures can increase central apneas in generally one in seven people, so it's not a certainty and concerns about it are overblown.

I am relatively ignorant compared to those who have already answered. But I also seldom have any obstructive events, mostly all centrals.

I suspect that centrals cause higher pressures, not the other way around.

Ordinary PAP machines don't respond to CAs, though I believe your ASV does.

I would try something cheap and easy before investing in a MAD. Foam cervical collars hold the neck in the optimal position for airway patency. This can reduce pressure needs. In my case, the prescribed pressures were bilevel, 22 IPAP/18 EPAP. With the addition of a collar, my APAP pressures run 10.0 min to 11.5 95% level.

Also, foam cervical collars don't bring the level of discomfort, and oral and jaw health issues that MADs do.
