Poll on response to CO2 hit

Sutty

I would appreciate any feedback from anyone who has had a CO2 hit, of any degree.
Basically interested on whether your symptoms started with shortness of breath (SOB) or some other symptom - would be interested to hear what. Also interested in whether you have/had a low air consumption on open-circuit, I know its not a precise measure but it might show something.
I'm wondering whether people who have low air consumption, and therefore are possibly less sensitive to CO2 (big assumption I know), are more likely NOT to have SOB as an initial symptom.

Many thanks,
Neil
