Methods for common drugs






Box G.1

Converting Infusion Rates.


Converting desired dose (mcg/min) to infusion rate (mL/min or mL/h):


<SPAN role=presentation tabIndex=0 id=MathJax-Element-1-Frame class=MathJax style="POSITION: relative" data-mathml='Desired dose(mcgmin)Drip concentration(mcgmL)=mL/min’>Desired dose(mcgmin)Drip concentration(mcgmL)=mL/minDesired dose(mcgmin)Drip concentration(mcgmL)=mL/min
Desired dose(mcgmin)Drip concentration(mcgmL)=mL/min


If using a volume infusion pump that uses a mL/h format, such as an IVAC Model 560, convert µg/min to mg/h:


<SPAN role=presentation tabIndex=0 id=MathJax-Element-2-Frame class=MathJax style="POSITION: relative" data-mathml='Desired dose(mcgmin)Drip concentration(mcgmL)×60=mL/h’>Desired dose(mcgmin)Drip concentration(mcgmL)×60=mL/hDesired dose(mcgmin)Drip concentration(mcgmL)×60=mL/h
Desired dose(mcgmin)Drip concentration(mcgmL)×60=mL/h
