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:
Drops per minutes= Total volume (mls)
Time (hrs) × Drop factor
60
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:
Volume remaining (mls)
DPM × Drop factor
1
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

Drop factor 60

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: Volume remaining (mls) DPM

Drop factor 1 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

Drop factor = 20 So, Drops per minute (DPM) = 500 8

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 = 360 60 = 6 hours Drop factor = 60 So, Drops per minute (DPM) = 2500 6

With the Infusion rate

Instead of giving the total time, the question may have the infusion rate. In that case you’d need to calculate the time first and then calculate the DPM. We know, Infusion Rate (ml/hr) = Volume (ml) Time (hr) So, Time (hr) = Volume (ml) Infusion rate (ml/hr) 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?

Practice Exercises Question 1 The total volume to be given to a client is 280 ml. The time over which this is to be given is 4 hours. The drop factor is 6 0. How many drops per minute will be delivered? Question 2 750 mls of normal saline over 6 hours needs to be administered using a set which delivers 20 drops per ml, at what rate should the infusion be given in DPM? Question 3 The total volume 3 L to be given to a client in 6 hours. The drop factor is 15. How many drops per minute will be delivered? Question 4 The total volume to be given is 15 00 ml over 480 minutes using a macro drip giving set with 15 drop factor. How many drops per minute will be delivered? Question 5 The total volume to be given is 950 ml at 120ml/hr. The infusion will be delivered via a micro drip giving set. How many drops per minute will be delivered? Question 6 The volume remaining is 2.25 Litre. The drop factor on the set is 60. The drops per minute (calculated when set up) is 200. How many minutes will this take?
