Vasodilation and vasoconstriction work hand-in-hand. This is why oxygen is given to people with cor pulmonale and RV pump issues even if they are satting well, since it can prevent/reverse pulmonary vasoconstriction which causes RV strain. Medically speaking, a vasodilator is a drug that can help dilate the blood vessels. Instead of laying blanket claims, lets use some evidence. While vasoconstriction usually occurs in the presence of low blood pressure, vasodilation can be the result of hypoxia (low oxygen levels), nutrient starvation, hyperthermia, and hormone imbalance..
