When the total volume is given…
..calculate the mL/hr
Total volume/total time in hrs=mL/hr
Ordered: 2000mL D5W to be infused for 24 hrs. How many mLs/hr must PT receive for 24 hrs?
2000(TV)/24 (TT)=83.33=83 mL/hr
When the mL/hr is given, calculate the ____ per minute
Answer: drops
Drop factor (gtt)/mL/Time in minutes x total hourly vol. =drops/min
Ordered: D5W to infuse at 83 mL/hr, DF is 10
10(DF)/60(mins) x 83 (Vol./hr)
10/60 x 83/1 =83/6=13.8 or 14 drops/min
When the IV tubing is micro drip, 60/mL, the drops/min will be the same as the ___
mL/hr
Step 1: 1000(TV)/8(TT)=125 mL/hr
60/60 x 125= 125 drops/min
