In assessing the effectiveness of Dopamine administration

Check the blood pressure or heart rate
Never as primary IV, always run as piggy back

To get a quick estimate of dose:

To convert mcg/kg/min to actual drops per minute, multiply desired mcgxkgx0.39
To get the 10 mcg/kg/min drip rate, take the weight in pounds, drop the last number and subtract 10% then multiply by 2

Receiving hospital must know if infiltration occurs by discontinuing the IV, and circling infiltrated area.

Optimal blood pressure is equal or greater the 90 but do not exceed 120 systolic
