I was able to solve the problem by using the ramp. You may also want to try EPR (expiratory pressure relief). My AHI was lousy on straight CPAP, so I set it back on auto.
Cheers for that Big-Dave, I have just downloaded ResScan but I have an S9 machine, so all I get is a record of sleep times (Which is about as much use as a chocolate fire guard!). My 95% Percentile is 13.5 cmH2o (An Autoset I used during a provent trial recorded Apnoeas at 16 cmh20. I do use Ramp now, I didn't before as my machine was an S6 and when the ramp kicked in on that it used to lift the mask off? As for EPR I think mines on Auto. Most Doctors seem to put mine and similar problems down to an underlying medical problem that is disclosed by Cpap, I don't agree with this generalisation. If I didn't have a problem before and I have it now, Cpap is the prime suspect.
I have been looking with interest at the 'Test' fittings on the bottom of my mask with a view of using these and feeding an equal pressure to my ears externally, I would be interested if anybody has any knowledge or input on this (Proposed?) method. Flying is a problem that I have as well, I take decongestants a couple of days before and always use 'Earplanes' ear plugs, taking off is bearable but landing is so uncomfortable for me I have avoided flying if I can, the noises in my ears are really painful!
