Question

An Iv infusing at 30 drops/min. The DF is 20. How many mL/hr are being infused at this rate?

Answer 1

Drop factor (DF) is number of drops in 1 mL. So drop factor 20 means 20 drops in 1 mL

From above understanding, we can find mL in30 drops

   1 mL = 20 drops (Given DF)

So, mL in 30 drops = (30 drops x 1 mL)/20 drops

= 1.5 mL

So, 30 drops = 1.5 mL

Given infusion rate is 30 drops/min, that is equals to 1.5 mL/min (30 drps = 1.5 mL from above calculation)

Now patient is receivind 1.5 mL/min

So, mL/hr = (60 x 1.5 mL)x 1 mL (60 min = 1 hr)

= 90 mL/60 min = 90 mL/hr

Hence, the answer is - infusion rate mL/hr = 90 mL/hr
