Can you diagnose asthma by hyperventilating.

With exercise induced asthma, it is always described as having to do with the volume of air that you breathe in through your mouth. So I was just thinking, if you intentionally hyperventilated, would it tell you something about whether or not it was EIA if you were or were not able to produce symptoms by hyperventilating?

It sounds ridiculous, but I did a google search for 'asthma + diagnose + hyperventilate" and a few things popped up, so I think it might be something that is done. I couldn't find anything that explained what they were talking about though. Has anyone ever heard of this sort of thing? I don't want to try it unless I can find out it's a legitimate thing because I value my dignity even it nobody's watching. :-P

I'm trying to figure out if what I have is exercise induced asthma and I can't get a break with the doctors. I was tested with a peak-flow thingy and didn't test positive, and I've been given several drugs that haven't helped me so I'm really anxious to find some kind of diagnosis.

  • when hyperventilation occurs over a small period of time, the respiratory centre senses the decrease of carbon dioxide and so automatically reduces or stops thebreathing process to enable it to restore to preset levels.a carbon dioxide decline did have a negative effect on the airways of asthmatic subjects,but led to no change in the healthy persons. The conclusion drawn was that “hypocapnia may contribute to airway obstruction in asthmatic patients, even when water and heat loss is prevented.”So while a loss of carbon dioxide has no affect on individuals without asthma, it does cause airwayobstruction leading to asthma symptoms among those with asthma.
