Timely one to ask since the forum is getting new breath.

Today I got a visit from the tech who got me fixed up with an O2 generator setup. I found that I've got a paralyzed diaghragm on my left so my breathing is compromised by about 25%. The unit is supposed to help. Tomorrow I talk with a surgeon.

Anyway...there are other reasons for being plumbed for O2.

Besides welding and grinding...and other sparky endeavors in the shop...how have others dealt with O2 generators?

I'm going to get one of the small units that go into a fanny pack/book bag so that I don't have to drag around the plastic tubing. I spent my career as an arborist tending my climbing lines in trees I sure hope not to have to do the same now when I'm working...er...playing...in my shop.
