increases renal and mesentric perfusion
Dopamine at a mid-range dose - answer 4-10mcg/kg/min
increases contractility and heart rate
Dopamine at a high-range dose - answer greater than 10mcg/kg/min
vasoconstriction and increases BP
Dopamine and Levophed infiltration - answer leads to tissue necrosis

rate by slowing conduction through the SA and AV node
