Came across a Sleep Review Magazine
Has sections for news, products, buyers guide, resources, digital edition. Reviews products (there was one on different masks recently; another one on home sleep testing equipment).
It appears aimed at individuals working in sleep disorders. As it also has those marketing sections, you'll have to search based on the title of the magazine, as I wasn't sure if that site would violate the rules or not.
Note: I'm an epidemiologist, not a medical provider.
RE: Came across a Sleep Review Magazine
It appears to me that best use would be to post specific articles of interest related to sleep apnea.
The forum's 501 C3 educational non-profit status permits fair use of copyrighted material.
(That's why we have restrictive rules on commercial links -- it protects that status.)
