IV calculations

Question 1

To Calculate IV Flow Rate in mL/hr

Answer 1

IV volume divided by hour

ex. Volume / Hour = mL/hr
1000 / 8 hr = 125 mL/hr

Question 2

To Calculate IV Flow Rate in drops/ minute

Answer 2

IV volume x Drop Factor
Divided by = gtt/min
Hours x 60 min

Ex. 1000 x 15 / 12 (hrs) x 60 (min)
