Unlike carbon monoxide (toxic) or excess nitrogen (i.e., not enough oxygen), an elevated level of CO2 triggers a breathing reflex (feeling of suffocation) that would be hard to ignore. (Not necessarily true with infants, though, according to one Web site). That's why holding your breath for a couple of minutes is difficult. Does that make dry ice safe in a boat cabin? Good question.
