Presumed effects of commonly used cardiovascular drugs in neonatal intensive care. X-axis (effect on vascular tone): the more to the right, the more vasodilatory effects; the more to the left, the more vasoconstrictory effects. Y-axis (inotropic properties): the higher on the Y-axis, the more inotropic characteristics. The larger the size of the (semi-)circle, the more chronotropic effects. It should be noted that the effect on vascular tone depends on the used dosage that determines which adrenergic receptors are activated (e.g., dopamine and epinephrine). Based on refs. 77, 78
