What is the formula for calculating Volume to be Administered (VTA)?

VOH*DD
 DOH 

What is VOH?

Volume on Hand


What is a useful formula for calculating the drip rate (DPM) needed to maintain a given dose per minute?

VOH*DF*DD
 DOH 

What is DF?

Drip Factor


What is DD?

Desired Dose


What is DOH?

Dose on Hand


What is VTA?

Volume to be Administered


What is DPM?

Drops per Minute


In both VTA and DPM formulas, what is always positioned at the upper left?

VOH


In both VTA and DPM formulas, what is always positioned at the upper right?

DD


In both the VTA and DPM formulas, what is always positioned at the bottom center?

DOH


In the DPM formula concerned with calculating perhr/min maintenance drips, what factor is added to the top center between VOH and DD?

DF(drip factor)


If you know how to calculate VTA, what is the single factor you need to add to the formula to calculate DPM?

add DF to the top center between VOH and DD


What is TIM?

Time in Minutes


What is a Drip Factor (DF)?

gtts/min of the particular drip set you're using


three kinds of drug calculations that are useful to paramedics

The first is concerned with finding the Volume to be Administered. The other two pertain to calculating drip rates for either "perhr/min" or "volumeovertime" infusion orders.
(1) VTA  find Volume to be Administered (2) gtts/min  when the per hr/min dosage is given (3) gtts/min  for volume over a given timeframe 

With a standard microdrip set (60 gtts/ml), the number of drops administered per minute always equals...

the milliliters delivered per hour.


How many ml/hr will a microdrip set to 30 gtts/min deliver?

30 ml/hr


How many ml/hr will a microdrip set to 43 gtts/min deliver?

43 ml/hr


How many ml/hr will a microdrip set to 28 gtts/min deliver?

23 ml/hr


How many ml/hr will a microdrip set to 120 gtts/min deliver?

120 ml/hr


If you needed to administer exactly 75 ml/hr via a microdrip set, how many drops per minute would you administer?

75


If you needed to administer exactly 12 ml/hr via a microdrip set, how many drops per minute would you administer?

12


If you needed to administer exactly 180 ml/hr via a microdrip set, how many drops per minute would you administer?

180


To find the amount of a drug per milliliter (mg/ml) in a given solution, what mathematical operation would you perform?

divide the total amount of the drug (eg: mg) by the total volume of the solution (eg: ml)


Prior to dividing the amount of a drug by the volume of a solution, you may need to make what adjustment to the drug amount?

convert it to the same measure that is specified in the orders (eg: gram to milligram, milligram to microgram, etc.)
