Studies related to CO2-induced vasodilation and vasoconstriction Vasodilation and vasoconstriction in simple terms YouTube Video about CO2 - Vasodilation effect References. Vasodilation, vasoconstriction and CO2: most potent vasodilator Among arterial dilators, the natural vasodilation agent CO2 is probably the most powerful chemical. The vasodilation effect is present in healthy people due to normal arterial CO2 concentration.
