Ideal AHI

[Apnea Infant]

Like Hojo, I am sure the collar helped me tremendously knock off most OSAs so that I could reduce pressures to help with leaks etc which were preventing good nights sleep.

Try an equivalent ie rolled towel beneath your chin. Some recommend those sleeping pillows-I forget the names-which can lock your head in a particular position . Maybe another member will chime in with the names.

You might want to try EPR of 1 and see how it goes. Some time has gone by and maybe you'll do OK as far as CA's. If not you can switch it back. Looking at your chart I don't see clusters of events happening so I don't think the cervical collar is needed.

If I change my EPR to 1, what should I look for to assess effectiveness? Lower AHI? More comfort? Less leaks? No Increase in CA's?

Mainly your looking for comfort. You do want to make sure your CA events don't start increasing. If they due than revert back. But it's worth trying it for a night or two.

Buckwheat chaff pillows can be configured to hold your head in a position that prevents chin tucking and reduce flow limitations. I use the CPAPfit pillow from amazon ($50) and have found it to be very comfortable and effective. I also use a soft cervical collar to prevent my mouth from opening to the point that it compromises the bottom seal of my F20 mask. I use the OTC collar from amazon. It comes in several heights and neck sizes. I find it to be quite comfortable.

I do use a CPAP pillow, not the same one as you....it has cut outs at the side for your mask to fit in. I use the same mask as you.

I'm a big proponent of at least trying a cervical collar if you haven't already, I found it really helps with OA and you may be able to reduce the pressure and hence, CA events.

I tried one at the beginning of my therapy, but didn't like it and sent it back to Amazon...it was too cumbersome...I may try a different model if you think it may help.

If you get fitted for a collar based on the assumption that it is to be worn for a neck injury, then yes, it will be way to large and uncomfortable.  The one I use is not that large, just enough to help keep me from tucking my chin down.
