# How do you calculate dobutamine?

- To
**calculate**rate: Dose (microgram/kg/min) x weight x 60) ÷ strength (micrograms/ml) = rate. - e.g. 2.5 microgram/kg/min x 100 kg x 60 = 15 000 ÷ 5000 microgram/ml = 3. ml/hr.
- To
**calculate**dose: Strength (micrograms/ml) x rate (ml/hr) ÷ weight ÷ 60 = dose.

Considering this, how do you calculate dopamine and dobutamine?

**Dopamine and Dobutamine** (Rule of 15): Concentration: 1 mL/hr = 1 mcg/kg/min. 15 X Patient's weight (kg) = mg of drug in 250 mL NS or D5W.

Similarly, how long can you be on dobutamine? The onset of action of dobutamine is within **1 to 2 minutes**; however, as much as 10 minutes may be required to obtain the peak effect of a particular infusion rate. The plasma half-life of dobutamine in humans is 2 minutes.

Thereof, how is dobutamine given?

**Dobutamine** is a medication used in the treatment of cardiogenic shock and severe heart failure. It may also be used in certain types of cardiac stress tests. It is **given** by injection into a vein or intraosseous as a continuous infusion. The amount of medication needs to be adjusted to the desired effect.

How do you measure dopamine?

The American Heart Association (AHA) has provided the fol- lowing **formula**, multiply 6 times the weight in kg times the desired dose in µg/ kg/min, divided by the desired amount of fluid to infuse in ml/h which provides the amount of **dopamine** in mg to add to each 100 ml solution prepared.
