When we use infusion pump for administering fluids, the rate is usually calculated in ml/hour.
The formula for calculating ml/hour is:
Volume of fluid in millilitre / time in hours
Here, the amount of fluid = 250ml
Time = 30 min
STEP 1
Convert 30 min to hours by dividing by 60.
= 30/60
= 0.5 hour.
STEP 2
Substitute in the above mentioned formula (Volume in ml / time in hours)
ie, 250/0.5
= 500ml/hour.
This is one method. We can also calculate this directly by using the formula,
Volume in ml / time in min x 60min / 1
ie, 250 / 30 x 60 / 1 = 500
In both ways, we will get the correct answer.
Therefore the nurse should programme the infusion pump at the rate of 500ml/hour
