Drops per minute (DPM) - Worksheet

Drops per minute (DPM) is used to calculate the IV flow rate of a given volume. When administering

intravenous via a gravity line, the rate of flow is determined using drops per minute. This measure is

calculated based on the total volume of the administered liquid, total time in hours and drop factor of

the giving set. For these calculations, you need knowledge about Unit conversion, Fractions, Long division, Long multiplication, and Decimals.

Formula:

Drop factor

Drop factor is the number of drops required to have any volume of 1 ml. It is an important factor in

calculating the drops per minute. Depending on the administration set the drop factor may vary. If it

is a Macro drip set with a bigger drop, it could have 10, 15 or 20 gtts/mil, on the other hand a Micro

drip set administers smaller drops and the drop factor is 60 gtts/ml.

Time remaining

If we know the DPM and drop factor, and the volume remaining to administer, it is possible to calculate the time remaining.

Formula:

Example

The total volume to be given is 500 ml. The time over which this is to be given is 8 hours. The drop factor is 20. How many drops per minute will be delivered?

Answer

Total volume = 500 ml

Total time to administer= 8 hours

Developed by Learning Advisers 2022

Drop factor = 20

So, Drops per minute (DPM) =

Including unit conversion

To calculate the DPM, the volume unit needs to be millilitre and time needs to be in hours. If the information is given in any other unit, they would need to be converted before calculating DPM.

Example

The total volume to be given is 2.5 L. The time over which this is to be given is 360 minutes. The drop

factor is 60. How many drops per minute will be delivered?

Answer

Total volume = 2.5 L = (2.5 × 1000) = 2500 mls

Time = 90 minutes = ଷ଺଴

଺଴ = 6 hours

Drop factor = 60

So, Drops per minute (DPM) =

With the Infusion rate

calculate the time first and then calculate the DPM.

We know,

Example

The total volume to be given is 250 ml. The time over which this is to be given at is 25ml/hr. The drop factor is 20 on a macro drip giving set. How many drops per minute will be delivered?

Developed by Learning Advisers 2022

Answer

Total volume = 250 ml

Infusion rate= 25 ml/hr

Drop factor= 20

So, Drops per minute (DPM) =

Another method

From DPM formula we can see that this already includes infusion rate.

Hence, we can write the formula like this,

Time remaining

Example

A macro drip giving set with the drop factor of 15 is administering 40 drops per minute (calculated when set up). The volume remaining is 120 ml. How long will this take (in minutes)?

Answer

Drop factor = 15

DPM = 40

Volume remaining = 120 ml

So, Time remaining =
