How would you design an experiment to test the effect of carbon dioxide levels on an animal's breathing rate?

Question

What experiment could you perform to test the hypothesis that higher CO2 levels in a cage equals increased breathing rates of the animal in that cage? [preferrably without violating animal rights ;]

Answer 1

That last bracketed statement is where your prob is. maybe by noting the effects of a small amount more co2 to oxegen ratio. then you can have some basis to prove your theory. It would be important to get a basis of the animals breathing rate under what the conditions are normally. Then increase the co2 a little. Be careful that if the breathing becomes to labored you can quickly allow oxegen, take the animal out of the cage, etc.
If you observe carefully you can do this even if the animal loses consiousness. It won't do it long term harm.

you might also look into scientific journals and see that/if this type of test was performed before and what the results where. To help set up your experiment or compare results.
