Your patient has a Heparin drip running at 29 mL/hr. The Heparin bag reads 25,000 units/ 250 mL. How many units per hour is the patient receiving? —

Step 1 is: Calculate the concentration of the Heparin solution in units/mL. 25000 units ÷ 250 mL = 100 units/mL. Step 2 is: Calculate the total units per hour being infused by multiplying the concentration by the infusion rate. (100 units/mL) × 29 mL/hr = 2900 units/hr. The patient is receiving 2900 units per hour.
