**When calculating an hourly infusion rate you need to:**

Divide the fluid needed in mL by the amount of time needed to deliver

e.g. 1000 ml needed delivering over 10 hours so..

1000 divided by 10 = 100ml/ per hour.

Sometimes the amount neededs to be rounded to the nearest decimal place

e.g. 1L needs delivering over 6 hours so...

1000ml divided by 6 = 166.6 would be 166.7ml/ per hour

If you need to work out the infusion rate per minute you times the time by 60 and divide this by the volume. Round this up to the nearest decimal place so...

1) Times the time by 60 ...............6 X 60 = 360

2) Divide the volume by 360 ............1000 divided by 360 = 2.77 round this to the nearest decimal place 2.8 ml/min
