350 mL of D5W/0.25 NS containing 10 units of Regular insulin is started at 09:00AM at a rate of 20 gtt/min. If the drop factor is 15 gtt/ml, at what time will the infusion finish?
Sol.
As Flow Rate = 20 gtt / min
Drop factor = 15 gtt / mL
Total Volume = 350 mL
So , Time required for infusion finish
= Total Volume × Drop factor / Flow Rate
= 350 mL × 15 gtt / mL / ( 20 gtt / min )
= 263 min
= 4 hr 23 min
If the starting time is 09 : 00 AM , then , the finishing time is 01 : 23 PM
