You charts don't look too bad, but mostly clear airway events, which may settle down in time.
As chill stated, reduce the EPR setting. Unless you have trouble breathing out against pressure, I would turn it down to 1 and see if that helps with the Clear Airways.
You also may do a little better with a minimum pressure at 6. Most feel that anything under 6 is suffocating. And it looks like you could bring down the max pressure too. How about a range of
6 to 13 and EPR of 1. Go with that for a week or so, and see if there is a difference in the C.A's.
