More portable concentrators

[Guest guest]

In addition to Inogen One and Sequal Eclipse and the Respironics Evergo,

this field is branching rapidly. There is now the Invacare Xpo2, the

Oxlife Independence, the Evo Central Air, and the Devilbiss Igo. The

Oxlife and the Devilbiss, like the Sequal, do offer continuous flow up

only to 3 lpm.

Maybe we'll see more advancements in this area soon.
