Thanks again Vchick. The CE2 looks like it might work. I don't understand how it works with the atomizer on top but I don't have to understand it. It just has to work. 
Looks like he would end up having to refill the 510 tank too often since it holds so little liquid. Great videos. Lots of food for thought.
Just a follow up. Hubby is breathing a bit better this am. I am hoping it was just a bug and all this work finding different equipment will all be moot.
All you guys/gals are the greatest. Don't know what I would do without all the help/info I have gotten here.
