Heparin Infusions and IV Calculations

• Calculating hourly heparin delivery: Infusion rate of 28 ml/hr from a 20,000 unit in 500 ml D5W results in 4120 units/hour.
• Safe infusion rate calculation for normal saline: 1,200 mL of 0.45% normal saline at 125 mL/hour equals 25 gtts/minute using a drop factor of 12 gtts/mL.
• Infusing 2,750 mL of normal saline at 150 mL/hour gives a flow rate of 58 gtts/minute with a drop factor of 15 gtts/mL.
• For 3/4 L of D5W over 5 hours and 45 minutes, the infusion rate calculates to 150 gtts/minute at a drop factor of 60 gtts/mL.
• Administering 1 liter of lactated ringer's solution at 125 ml/hr yields 41 gtts/minute using tubing calibrated at 15 gtts/mL.
• Infusing 1 liter of NSS over 24 hours via microdrip results in a flow rate of 42 gtts/minute with a drop factor of 60 gtts/mL.
• Remaining 200 mL in IV bag infusing at 80 ml/hr will run for 4.0 hours.
• Setting an IV pump for 1,000 mL of Normal Saline over 8 hours results in a rate of 125 ml/hour.
• For 1,000 mL of Normal Saline over 8 hours using a drip factor of 15 drops/ml, the rate is 61 gtts/minute.
• A patient diagnosed with pneumonia receiving 1,000 mL normal saline will require replacement at 10:00 PM on the same day after starting at 1:00 PM.
• Administering 250 mL normal saline IV over 4 hours leads to a delivery of 25 gtts/minute.
• Infusing 1,000 mL of normal saline over 6 hours results in a rate set at 169 ml/hour.
• Infusing 500 mL of lipids over 24 hours should be set at a rate of 24 ml/hour.
• Administering 350 mL packed red blood cells over 2 hours at a drop factor of 10 gtts/mL translates to a flow of 29 gtts/minute.
