Not really a question, just desired to share, I've discovered my leak issue with Resmed Airtouch. Finally resolved !!!!! 0 AHI past 2 days. What I've discovered is, during sleep I have a tendency to sweat or my face get's oily, I'll wake up, adjust my mask go back to sleep, another 2-3 hours, I wake up adjust mask. Tighten straps.
Several nights ago, I woke up, while adjusting my mask, I noticed how slippery the mask was on my face surface. I clean mask cushion, washed my face, went back to sleep, no wake up. Next night, I awoke sweaty, alot of sweat on my pillow, same cleaning process. I turn on my ceiling fan, all was well. Each night now, I take time to clean mask cushion, before I would just quickly wipe mask/cushion. I wash my face surface throughly, not just wiping face with wet towel before bed

I leave ceiling fan on, regardless of indoor temps. I'm able to loosen straps. No more mask leaks. Never realized slippery face surface would cause massive leaks, I thought it was the straps, this or that. Hope my discovery will help others.
