If the total volume to infuse is 2000 mL over 20 hours, what is the hourly flow rate?

To determine the hourly flow rate, you need to divide the total volume of fluid to be infused by the total time for the infusion in hours. In this case, the total volume is 2000 mL and the total time is 20 hours.

Calculating the hourly flow rate involves using the formula:

Hourly flow rate = Total volume / Total time

Using the numbers provided:

Hourly flow rate = 2000 mL / 20 hours = 100 mL/hr

This calculation shows that the flow rate necessary to infuse 2000 mL over 20 hours is indeed 100 mL/hr. This rate ensures that the patient receives the appropriate amount of fluid steadily over the defined period, which is critical in maintaining proper fluid balance and ensuring effective IV therapy.
