Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that breathing high concentrations of carbon dioxide can kill a person?

Yes. A literature review of carbon dioxide poisoning reports that concentrations above 10% can cause coma and death in humans, with levels above 30% causing rapid loss of consciousness. Animal studies in rabbits and rats likewise show high CO2 concentrations are lethal, though those are non-human models.
