Describe the general effects of DA at low, high, and intermediate doses.
Low 1-5mcg/kg/min: Renal efx (inc renal blood flow and UOP)
Int 5-15mcg/kg/min: Renal and heart efx (inc renal blood flow, HR, heart contractility, CO)
High >15mcg/kg/min: Alpha-adrenergic efx (Inc BP, vasodilation)
FYI if must use DA>20mcg/kg/min, better to use E/NE... also FYI no renal d-adj needed for DA
