Pressure for Full Mask vs Nasal Mask

I currently am using a Phillips Dreamwear nasal mask. I am considering changing to a full coverage Dreamwear mask. Will a pressure change be required with this mask change?

Maybe....maybe not.

Normally though when mask types are changed the pressures are not routinely changed as standard practice.
A lot of "it depends" gets involved.

Best thing to do is start with same pressure and monitor result. Sometimes a little bit of an increase is needed but it's not set in stone.

Thank you for the answer Pugsy.. I appreciate the help!
