I found some studies from OSHA (the United States gov't agency) about very high carbon dioxide levels in certain industry settings, such as where dry ice is used. Effects on cognition are significant at high levels.

But understanding the effects of CO2 in more every day situation seems more complicated. It is also hard to find good rules of thumb about guidelines about when to look more deeply and pay to get measurements.

But I haven't found high-quality studies that talk about residential settings. My Google results seem to be populated with companies trying to sell stuff. So based on maybe 30 minutes of research, I remain practically skeptical.

I'm interested in learning more, Starting with the chemistry and airflow (?) properties of CO2, and then working up to biology. Would you mind sharing high-quality resources you recommend?
