Your machine is in 'S' mode... fixed iPap and ePap pressures. It is registering OA events but it is not letting us see any Flow Limitations due to the mode... so we can't be sure if more pressure would help. Pressures are already pretty high, your machine only goes to 25.
I'd ask your physician if there's a reason you were not put in vAuto mode. We could try and give you settings but that's pretty scary given the extreme situation you're in.
I would be interested in a zoom-in to one of those clusters of OA's... are the breaths flat-topping or otherwise distorted? That's the kind of thing we'd see FL's for if the machine was allowed to graph them. Can you correlate the clusters with your sleeping position? OSA is often positional.
