Full Face Mask Sizing Templates

[WakeUpTime]

I've been reading so many comments about mask leaking and mask styles that made me interested again in ResMed's sizing templates -- which are actually supposed to be for use by the DME's instead of patients.

Since I received more service from the McD drive-thru than from my DME, I went the online route for subsequent mask orders -- and continually mess up with sizing. The confusion might also be brought about by "how" the sizing templates are to be used.

For example, the lower chin line is simple enough, though the upper size indicator tabs are confusing. You'll get several credible industry answers as to which one to choose:

(1) Choose the size indicator tab that meets your nose bridge

(2) Choose the size indicator tab that meets your pupil

Note that (1) and (2) are different for me, and maybe others. Which one is more accurate?

(3) But if it's XYZ-mask, it meets the face a little differently so you might instead choose this size... [If that's the case, why doesn't ResMed (and the others) specifically state that?]

(4) If you're a mouth-breather you might want to get a little bit larger because you're going to open your mouth a bit once asleep. [Although it may be true, the experts say a big "no" to that.]

Has anyone out there used the ResMed's sizing templates and have you found them to accurately predict the size? Is there a better way to "read" them?

I never used them as my DME will always take mine back if it doesn't fit right. The few times I dealt with them directly, they never used a template. Now they just ship my stuff UPS although they are only 15 miles away. The templates that I have seen from various companies always struck me as troublesome to use and inaccurate. I am a mouth breather and agree with (4) in getting one size larger. I know that this does not answer your question, which is a good one, and makes me wonder how much effort these companies put into their templates.
