Resmed N30 nasal mask
Just received the N30 mask and tried it briefly for fit and function.
The mask is similar to one of Res Med's nasal pillow masks, the P10. The P10 has a similar light weight strap and front hose, but its nasal pillow cushion has no rigidity and I found that this caused the main hose to pull on and deform the cushion and break its seal as I moved around. Also, the pillows impressed me as an irritating, intrusive and non-ideal way to provide air in a nasal mask.
The N30 is also a very light weight mask. The cushion is light and not bulky, very soft and conforming and yet seems substantial enough. And, at least in my awake test, seals well. It fits into a rigid frame that doesn't curve as much toward the face as the N30i cushion rigid front pieces, and thus doesn't look like it will cause discomfort where the nose meets the face, which was a problem for some people with the N30i design. We'll see if it stays in place and sealed and how it performs during sleeping conditions
The front hose is light, and only about a foot long. It's fixed to the front of the mask frame, with the free end as a single axis swivel for connecting to a main hose. I'm going to use a hanger to fix the main hose to the bed's headboard to keep the hose connection from swinging around and tugging on the mask.
The exhaust diffuser seems to be excellent - it's a slot that runs all the way around the front of the mask frame, and doesn't stream air, at least at modest pressure; it just distributes it gently and evenly.
The headgear consists of a strap with adjusting buckle that splits to go on top of and in back of the head - very thin and lightweight. The whole mask is extremely light and unobtrusive when on your head and face, and very quiet with the air running (I use very modest pressure).
If it stays put, the only considerations I see so far are:
1. The thin, lightweight strap will probably require frequent replacement, and may not provide enough friction and traction if users have bulky or slippery hair configurations.....it's a very skinny strap.
2. The short front hose and its connection suggests that the user may want to use some care in hose management - that is, the main hose will not be a non-issue as it is with a top connecting mask. The mask is so light in weight that any hose dragging or twisting could affect it.
