I picked up a rental last yesterday. A Resmed 10 with an F20 full face mask.
Was given a air flow starting at 7 and ramping to 10-18.
I immediately hated it. I kept feeling like I was not getting enough air and that exhaling was laborious. I've always wanted to skydive but never have because I feared how hard it would be to breathe while descending. This is exactly what I pictured that feeling to be like.
I don't think I can lower the starting pressure myself and instead need to wait until the Dr at the issuing clinic returns on Tuesday. I'm going to try it again tonight, and earlier in the evening, to see if I can get used to it while just relaxing in bed but my initial impression isn't very positive but hope I'm just overreacting.
