Full Face vs. Nasal Pillows? Mouth Breather

Too many variables to determine if someone else might do well with nasal pillows. What are the pressure settings? What is the person's nasal anatomy like? (I have severely deviated septum and even the smallest pillow wouldn't fit into one side of my nose.) Allergies and congestion can make breathing through nose difficult so mouth breathing is the natural fix. Mouth breathing totally defeats xPAP therapy. I found chin strap obstructed my airway more than it already was by pushing lower jaw back. (Tried PapCap, Ruby, Regular chin strap). Dental devices that are supposed to at least stop snoring pull the lower jaw forward. Who ever thought a chin strap was a solution for CPAP users that mouth breathe are ignorant of the anatomy of OBS.

Mouth taping was self-defeating. When I couldn't breathe through my nose, I would wake up tearing at the tape over my mouth so I could get a breath. For me, mouth breathing is a functional necessity when congestion makes nasal breathing difficult.

So obviously, it is difficult to determine ahead of time whether somebody would be successful using hybrid or nasal pillows. The newest ResMed Full Face masks (Airfit F10) are very light and much less obtrusive. And may be an easy solution to somebody who previously was unsuccessful with the large bulky FF masks of yesteryears.
