Re: CO2 builidup in moto helmets
If you go back and look at my original post, I used words like, "maybe", "I'm wondering", "I don't know", and "food for thought". I'm not an expert on the matter but I am an aviation physiologist and I know there are aviation related CO2 buildup issues (such as headaches, fatigue, faintness, etc.) when enclosing one's face with either a full-face helmet or respirator. That's why pulse oximeters are finding their way into military cockpits these days.
Having said all that, do I think that CO2 buildup was responsible for this guy fainting and falling off his moto and crashing? Probably not..but I don't think you can just rule it out as a possible contributing factor. Just my 2 cents.
