Order: Infuse 50 mg of Amphotericin B in 250 mL NS over 4 hours 15 mins; Drop factor: 12gtt/mL
What is the IV flow rate?
What is the drip rate?
The amount of fluid to be infused = 250 ml
Total time to infuse = 4 hours 15 minutes
= 4*60 minutes+ 15 minutes
= 240 minutes + 15 minutes
= 255 minutes
Drop Factor = 12 gtt/ min
IV Flow rate ml / hr = Volume ml
Time in hours
= Volume * 60 / Time * 60 ( the time is to be converted in to minutes for easy calculation and should be multiplied and divided by 60 )
= 250 ml * 60 / 255min
= 15000 / 255
= 58 .52 ml / hr
Drip rate = millilitres per hour * drip factor / minutes
= 58 .52 * 12 / 60
= 11.7
= 12 drps per minute ( round)
