I, too, liked the "For Her" settings on the Airsense 11. It still boggles my mind that, with so much info out there on CPAP issues, the doctors are clueless. I'm the type who researches a lot on my medical issues (I'm 69) and almost know more than my doctors, haha! Best of luck!
To Island Owl, after having a ResMed 10 for 8 years, I switched to AirSense 11. Huge mistake, same problems as you, only I got VERY VERY sick with severe sinus infection, mucous buildup in throat, had to see a pulmonologist. Pressure was also too high. My solution was to go back to Airsense 10 within 90 days. Solved my problems.. CPAP company lied and said Airsense 10 no longer manufactured. They made more money on Airsense 11. There are definitely manufacturing problems with the 11. It has more of an "auto" program than older machines. I also never used the water chamber. Personally, may I suggest a totally different machine? Best of luck.
