How to tell whether I need bipap instead of cpap?
Hi, I've been on cpap for 7 months, and while I'm sure my tiredness and headaches were sleep related(since whenever I sleep without the cpap I get heavy headaches), I've been wondering whether I could be needing bipap instead of cpap.I've never gotten 8 full hours of uninterrupted sleep in these 7 months... at most 6 and a half, and I also have a feeling that I do too much effort to exhale(even with EPR set to 3). Also, I don't wake up refreshed as when I was a kid. I've experimented with pressures from 5-9 and all of them have been kinda similar, with almost all events being clear airways instead of hypopneas. My sleep study gave 7 AHI, with like 6.5 being due to hypopneas.
Maybe all of this is psychological, so I want to ask what data can I look at to determine whether I need a Bipap instead of a Cpap.
