I have been having a lot of success over the last 1 - 2 months with my Simplus, but am vexed by the occurrence of dry mouth. I used to use a P10 nasal pillow mask and would get this problem, but that seemed likely due to mouth leakage; in fact I could never conquer mouth leakage and had to give up the pillows even though they are more comfortable.
I am at a loss to figure out what causes dry mouth in a FFM, since presumably both oral and nasal areas are receiving the same air flow, and my nose does not dry out. I have the Humidifier set at 5 (out of 1-8) and this has worked fine in the past.
Any ideas for cause or cure?
Various remedies to google that might help:
2. Orajel Dry Mouth Relief Gel
3. Biotène® Oralbalance Moisturizing Gel
Have no idea about the cause but hopefully, these suggestions will get you started.
What are your leak rates like with the Simplus? If you have a large leak and are mouth breathing, that could explain the dry mouth.
The nose is designed for long term breathing - it stays sufficiently hydrated by design. The mouth is more designed to be opened and closed and the tongue moved around it to distribute moisture. It makes sense that it would get dry when open and motionless at night. I've had this happen before CPAP when I had nasal congestion.
