  1. IV Flow Rate Equation
    An IV is ordered to infuse at a rate of 125 mL/hr using a set calibrated at 10 gtt/mL. What is the flow rate?
    (Total Volume X gtt Factor) / Min

    • 125 mL X 10 gtt /60
    • 125 X 10 = 1250
    • 1250 % 60 = 20.8
    • = 21 gtt/min
  2. Infusion Time
    Calculate infusion time for an IV of 500 mL to infuse at 50 mL/hr
    • Infusion Time = volume % mL/hr rate
    • 500 mL % 50 mL/hr
    • = 10 hr
  3. Formulaic Method

    The Dr. ordered 30 mEq. The the bottle is labeled 80 mEq per 5 mL. How much do you give?
    • D x Q = X
    • H

    • D= Desired
    • H= Have
    • Q= Quantity needed

    • 30 mEq x 5 mL = 0.375 x 5 = 1.875 = 1.9 mL
    • 80 mEq
  4. What are the macrodrip set calibrations?
    • 10 gtt/mL
    • 15 gtt/mL
    • 20 gtt/mL
  5. What is the microdrip set calibration?
    60 gtt/mL
  6. Convert fractional hour to minutes

    The order is to infuse 1000 mL at 75 mL/hr. Calculate the infusion time.
    Calculate min by multiplying 60 min by the fractional.

    • 1000 mL = 13.33 hr
    • 75 mL/hr

    • 60 min x .33 hr = 19.8 = 20 min
    • Infusion time is 13 hr 20 min.
  7. Completion Time

    An IV infusion time is 13 h 20 min. What is its completion time if it was started at 10:45?
    Completion time is calculated by adding the infusion time to the time the IV was started.

    • 10:45 am
    • +13:20
    • 23:65
    • change 65 min to 1 hr 5 min = 24:05
    • = 00:05 = 12:05 a.m.
