Change Doc?

Seems as doc is going by the averages and not looking at the waveforms. Yeah, what a shocker! I'm concerned about Centrals and CSRs but he's not. Just switched to BiPap which I've heard makes Centrals worse. however, both pressures are running 9 to 11 like the Cpap was. Should I switch docs? I hate to do it. Confronted doc about all my concerns and I will be seeing his partner net month.

Does anybody know why FlowRate waveform disappears from Sleepyhead display half way through the night? All other data and alerts are there?

Thanks,
Rob
