FFM Cushion Leak with Data

Yes, but I may move a bit too much.  I noticed this morning around 4 am when the air escaping outside by my cheek that I apparently was in the middle of moving my jaw around.  I haven't downloaded the data yet to look at the (leak) info but I felt that I had a better night last night, which might be because I had tightened the lower straps even more.

The FFM ambu masks at the hospitals have air in them so the cushion feels better, I wish mine were that way but my cat might sneak up and enjoy sinking her claw into it while I sleep.  Grin

RE: FFM Cushion Leak with Data
As a former EMT I used these frequently for training and fortunately never on a real patient.

The seal on these is formed entirely by hand pressure (no straps) but considerable pressure.  Modern CPAP masks are designed to seal with the CPAP pressure pushing a 'flap' seal against your skin with just enough strap tension to keep the mask in place.  Many users tighten the straps too tight.

An older nasal mask but good at fitting, even at higher pressures, is the Mirage Activa Nasal mask.  It's design has a "bellows" between the mask frame and the seal meaning that properly fitted it can handle a lot of motion (side sleepers) and literally floats on your face.  It works on my Full beard.
