Intravenous Infusion Calculations
Drip Rates- is when the infusion volume is calculated into drops.The formula for the Drip Rate:
Drip Rate=Volume (mL)Time (h)
Example 1
A patient is ordered to receive 1000 mL of intravenous fluids to run over 8 hours. Cal- culate the drip rate.Solution:
Volume=1000 mL.
Time=8 hours.
Substituting in the formula gives:
Drip Rate=1000 mL8 h
=125 mL/h. Therefore, the patient will receive 125 mL of fluids per 1 hour. Note:When the drip rate is given in minutes, convert the minutes to hours by dividing the required minutes by 60 (since 60 minutes in one hour).Example 2
Convert 30 minutes to hours.
Solution:
Write as fraction to give:
3060=0.5 hour. Calculation of drips rates in drops per minute (dpm)
There are two standard giving sets of drip rates:
1. Macr oDr opFactor - dr opsize is normally 20 dr opsin 1 mL. 2. Micr oDr opFact or- dr opsize is normally 60 dr opsin 1 mL. The formula to calculate drip rates in drops per minute (dpm): Drip Rate (dpm)=Volume of IV fluid (mL)Time to run (h)Drop Factor (drops/mL)60 (min/h)
Example 2
A patient is to receive 1 L of Hartmann"s solution over the next 12 hours. What is the rate of infusion in drops per minute (dpm), if the drop factor is 60 drops per mL.Solution:
Volume=1000 mL, since 1 L=1000 mL.
Time=12 hours.
Drop Factor=60 drops per mL.
Substituting these values into the drip rate formula gives:Drip Rate (dpm)=1000mL12
h60 drops/mL60 min/h=83.83384 drops/minutes.
The formula to calculate how many hours will it take for the IV to complete before it runs out is:Time (hours)=Volume (mL)Drip Rate (mL/hour)
Example 3
The volume of the fluid is 1000 mL and the IV pump set at 62 mL/hour. How long will it take for the fluid to run?Solution:
Volume=1000 mL.
Time=62 mL/hour.
Substituting these values into the formula gives:
Time (hours)=1000mL62
mL/hour16 hours.Other resources
