for BP 70-100; inotropic and vasopressor effects. Lower doses produce renal and mesenteric vasodilation. Higher leads to cardiac stimulation and renal vasodilation, which increases HR and myocardial O2 demand. Dopamine . does not cross the BBB. 10mg/kg/min produces vasoconstriction. NE is only used for severely decreased BP (

Finally, although the above studies indicate that vagal stimulation can produce negative inotropic effects, it should be briefly noted that the effect of parasympathetic activity on ventricular contractility is more complicated and thus modifies the picture painted above.

Inotropic agents change the cardiac output curve. Positive inotropic agents produce increased cardiac output. The equilibrium point shifts to a higher CO and a correspondingly lower RA pressure. RA pressure decreases because more blood is ejected from the heart on each beat. Negative inotropic agents produce decreased contractility and decreased CO
