Would leaks cause centrals or hypopneas? Obstructives have gone down and stayed down on the full face mask. I always suspected my mouth openings were interfering with the machine being able to detect events, is that possible?
I returned the mask for an extra small of the same kind, fits a bit better but still leaks out the sides of my nose bridge a bit. Not sure what to do about that, my nose bridge is high and skinny. Also I'm already not swallowing the massive quantity of air that I was on the small, so somehow that was related. I'll give this one a few nights now and try to figure out the fit.
Leaks would not cause centrals. Hypopneas may be possible if it is a large enough leak. Centrals can be the result of major arousals from sleep that could happen from the annoyance of a large leak. These centrals are not the same kind that most people refer to when diagnosing central apnea but they can show up in the data if the data is not being manually reviewed using waveforms (like in a sleep study)
REMZZ mask liners work well for some people with small leak problems (especially around whiskers for men and sometimes for leaks around the eyes. like everything else cpap related it is important to get the right size liners)
Common sense afterthought: Be sure you are not over tightening the mask. Over tightening will cause leak too!
Would you mind expanding on why you didn't like the hybrid? Did it leak as well or was it just uncomfortable?
I have tried to fit the hybrid masks and most all come back as not working well. The newest one is the Amera View mask. I personally tried this one and found it uncomfortable, kind of hard to breathe. I am not sure why I didn't like it. Maybe because I had a mask I liked.
Clinically, I don't know why they are not more successful. Maybe it is the structure between the nares and upper lip that can't be easily fit with something that also covers the mouth and rests below the lower lip. There is a lot of bone structure there and for whatever reason it is very hard to fit and in my opinion not comfortable to wear. I have sent one Amera View out (after fitting) recently that has not come back yet, but that is not to say it was successful! I just don't know yet.
