'positional therapy", mainly improving head/neck alignment to prevent obstructing the airway.

if this were mine, with the wonderful, quick responding machine, I would bump my minimum pressure up - I would use the following formula:

minimum pressure - change to [median pressure - 2]  (11.6 - 2 = 9.6 cm)
maximum pressure - change to [95% pressure + 1]  (15.9 + 1 = 16.9 cm)

I think the foam collar will help.

I also think that your chart shows that the median EPAP stayed about 10 cm, even though EPR was off, then 1, and then 2.  That suggests you will need at least EPAP of 10 to eventually shed most of the apneas.

Good luck, and go slow!
