Heparin Drip Calculation Reference
Heparin Infusion Rate: Total Units (in IV bag) = Units/hour
Total Volume (ml) X (ml/hour) (Round to the nearest tenth)

Your patient has a DVT is ordered for a heparin infusion to start at 18 units/kg/hour per the
practitioner’s order. His weight is 75kg. The heparin infusion comes in a 500ml bag with 25,000 units.
Calculate the starting rate of the infusion (ml/hour).

Step 1: Calculate the starting units per hour.

18 units X 75 kg = 1350 units/hour

Step 2: Calculate the starting rate of the Infusion (solve for X).



Heparin Infusion Rate: 25,000 units = 1350 units/hour
500ml X (ml/hour)

25,000 units (X ml/hr) = 675,000

X ml/hr = 675,000
25,000 X = 27 ml/hour


OR
1350 units x 500 mL = 675,000 = 27mL/hr
1 hour 25,000 25,000

The same patient’s heparin assay indicates the infusion dose should be increased by 200
units/kg/hour. Your patient is currently receiving an infusion based on 18/units/kg/hour. What is the
new rate for the infusion (note: use the same initial weight to calculate the new rate).

Step 1: Calculate the new units per hour.

18 units X 75 kg = 1350 units/hour + 200 units/kg/hour = 1550 units/kg/hour



Step 2: Calculate the new rate of the infusion (solve for X).

Heparin Infusion Rate: 25,000 units = 1550 units/hour
500ml X (ml/hour)

25,000 units (X ml/hr) = 750,000

X ml/hr = 775,000
25,000 X = 31 ml/hour
