In Sleepyhead, zoom in on the flow rate and mask pressure during these events.  You will see the machine remains at EPAP pressure and does not change until the apnea ends by you taking a breath.  Even if the periodic breathing is separated by hypopnea with shallow breathing, the mask pressure follows respiration, rather than leading it.

Jerry, what is going on?  You have had high central events since you joined in July, and at one point had an appointment to discuss it with your doctor.  I have no idea what the outcome of that was.  You have never achieved a consistent and acceptable AHI.  What are you doing about it, and how can we support you in getting ASV?
