I was excited about SensAwake when it was first introduced and have watched the various sleep apnea forums for user's experiences. I have been unable to find any users saying the SensAwake feature has done anything beneficial for them. If you have any links to actual users good experiences with SensAwake, I would appreciate seeing them.
Forums tend to be populated with people that have various problems with CPAP. Sometimes I wonder what would happen to these forums if someone invented a CPAP device that made it easy and 100% effective. Maybe everyone that tried one would sleep great the first night, get up and have a fully active great day, totally change their lifestyle, and forget about the forums without coming back to tell us the good news? :):)
I often wonder about the forums myself banyon. We also see quite a few repetitive personalities on each forum. Most people just pass through.
Since starting CPAP have you noticed dry mouth? You have a high pressure (16 cm) and are using a nasal mask. This is often a recipe for mouthbreathing or leaking air out of the mouth. This can negate the effectiveness of the CPAP therapy. Ask your wife if she notices mouthbreathing or air leaking out of your mouth. Also, what is the exact model of the machine you are using?
