My son has been using a bipap since March (4 months). He has moderate obstructive apnea after T&A removal. At the sleep study to figure out settings for his machine he had central apneas too. At his last appointment in the sleep disorders clinic the doctor said she didn’t think his machine was reading his apnea right since he’s a child. His AHI was 7, there were nights that his score was at 22! The last week he has pretty much refused to wear his mask, I didn’t fight him he has autism. He seemed to wake up more refreshed and awake when he didn’t wear it. When he does wear it he gets up in the morning takes it off and goes back to sleep. Does anyone know if the machine would be wrong with its reading? And why would he be more tired after wearing his mask at bedtime?
