Changing Settings reccomendations

There are likely reasons why you need a higher PAP pressure...
Gotten older; gained weight; and a few other things. 18 is up there; but not unreasonable.
Some machines can only generate 20; some to 25.

Keep in mind the units are centimeters of water. That's the gravity head pressure one would get from 18 cm of water in a vertical tube.
That's about 0.3 PSI.

If you can, get a new machine. The S8 compact is obsolete.
An S9 would be better; plus make it possible to readout your data yourself.

THank you Mongo I'll psss this along to my physician
