Sorry if this post appears more than once on this page. I have tried posting twice but nothing appears. I had added links to ResMed and F&P pages. Perhaps that was the problem, so I removed them.
When you say headgear, am I right in thinking you mean the straps but
none of the plastic/silicon part that fits on your nose?
Just trying to visualize things. As I understand it, the mask
part of the F&P Brevida Air Pillow covers your nose, while the ResMed
P10 rests on the outside rim of your nostrils, with prongs as you
mentioned. If I went for a nasal mask, I might prefer the Brevida
design of the nose piece, as shown in your photo above.
I wish I had more opportunity to try different masks. I currently live
in Japan. I went to an ENT doctor who made me do an at-home test and
then sent me the ResMed AirSense 10 Auto plus a full-face ResMed mask
and F&P Eson 2 nasal to try. I then did a PSG overnight test at a
larger hospital and was supposed to do a mask fitting there, but the
technician/nurse just asked me what I had already and gave me the
ResMed N20 mask, without letting me try on others.
I don't want to go back to the overnight hospital because they are not
flexible as far as letting me try and choose my own mask. The ENT
doctor is helpful but has no expertise on fitting masks and doesn't
have them on hand to try out. However, I can call up the supplier
directly and they will provide me with various masks, as long as I
phone the ENT doctor and get his approval. This is all covered by the
Japanese national health insurance system. However, I imagine I cannot
keep asking the supplier for alternative masks indefinitely, so I
think I will try what I have, then ask for one more from the supplier,
and if that doesn't work, I will buy another one out of my own pocket.
