Heparin Protocol
Bolus: Heparin 80 units/kg. Bolus vial contains 1,000 units per mL. Infusion: Heparin 18
units/kg/h using a concentration of heparin 25,000 units in 250 mL of NS (100 units/mL).
Calculate the number of mL/hr required to deliver continuous infusion.
154 lb / 2.2 kg= 70
18 x 70 kg = 1,260 units per hr
250 ml/25,000 = x ml/ 1,260
315,000 = 25,000x
x= 12.6
