Toth – you would be considered a “complex sleep apnea” patient…..and I think bilevel is best choice. I use the ResMed S9 VPAP which has an alarm that can be disabled.
Your alarm may be going off due to mask leak from an ill sized, or ill fitted mask….maybe due to your beard?
So I hope you won’t dismiss bilevel. If you want to talk to doc about auto cpap, ask about S9 Auto cpap.
But resolve the mask issue as a priority
