Heliox and Asthma

[Ed Palma]

Hello everyone, I've tried searching the board for a topic regarding heliox and how it interacts with people with asthma. Does anyone have a link that I can use to point me in the right direction? Any asthmatic divers out there? :huh:

Here's a study on the use of Heliox with exercising patients afflicted with COPD:

I remember reading about several months ago. Sounds like solid logic to me. I know someone with severe asthma, so I was interested in the topic. Basically, it's easier to breath, since the He molecules are smaller. If a patient is having trouble moving 100% O2, they can move a 50/50 blend easier.

The clinical side of UpToDate is much better but here is a link to the patient UpToDate.
