I was under care of "The-Sleep-Doc-from-he--" for a long time.  His criteria for treatment was
* was the Respironics brick machine on enough hours?  He literally checked every appointment. 
* he asked a bunch of questions  

 

Im inclined to check details too

This is just an experience I had from one night, so I don't know how useful it is, but I believe that I had a little more pressure on FFM than pillows. 

Long explanation: I started out CPAP with nasal pillows/cushions because I don't mouth-breathe, but my mouth would fill with air and puff up my cheeks (chipmunk cheeks), and then the air would pop out of my lips. The DME guy said to use a FFM because it would equalize the pressure on both sides of the mouth. That did help reduce them, but I ended up also having to wear a soft cervical collar to eliminate them completely (that kept my jaw from relaxing and dropping back to the point where my tongue stopped blocking my airway). 

With the F30i and cervical collar, I stopped having the puffy cheek problem. But the last couple of nights I've been using the F40 mask, and even with the cervical collar, the cheek puffs are back. Last night I was having them during the first hour or so of bed, so thinking back to what the DME guy said, I switched from the recommended "pillows" setting to "full face". I did not "feel" any difference between the two settings, I did not have any puffs after I changed the setting, so I'm going to leave it that way for a while. 

Note: I use fixed pressure of 8cm
