How to Calculate IV Push Rate
Understanding IV Push Rate Calculation
To effectively calculate the IV push rate, begin with determining the total volume of the solution and the desired administration time. Use the formula IV Push Rate = Total Volume (mL) / Time (min) to find the rate at which the IV should be administered.
Preparation Steps
First, ensure the correct dosage by checking the medication order and consulting pharmacy guidelines. Then, calculate the volume of normal saline required for diluting the medication to the necessary concentration. Both steps help in achieving the desired medication efficacy and patient safety.
Tools Required
Utilize tools such as RxToolKit calculators and dimensional analysis to ensure precision. Relying on the universal formula for dosage calculations can streamline the process and reduce errors.
Verification and Collaboration
Always verify the dosage calculations with another RN, especially when dealing with potent medications or titrating doses. Collaboration enhances safety and improves outcomes by cross-verifying important calculations.
IV Tubing and Drip Factors
Choose the appropriate IV tubing based on the medication and required flow rate. For precise and small volume infusions, use microdrip tubing (drop factor of 60 gtt/mL). For larger volumes, macrodrip tubing is appropriate with drop factors ranging from 10 to 20 gtt/mL. Adjust the drip rate based on the type of tubing to meet the calculated IV push rate.
How to Calculate IV Push Rate
Understanding IV Push Rate Calculation
To effectively administer intravenous medication, understanding how to calculate the IV push rate is crucial. This process ensures medication is diluted and administered over the correct time frame.
Steps for Calculating IV Push Rate
Begin by determining the total volume needed for the medication and the time frame over which to administer it. First, verify the correct medication dosage, possibly consulting another RN or pharmacy if needed. Adjust the frequency of calculations when dosages change or titration is involved.
To prepare the medication, calculate the amount of normal saline required for dilution to achieve the desired drug concentration. Use the formula: X = total units needed / available units per mL * total mL available. For instance, when using a medication such as heparin, adjust the volume based on available concentration and required dosage.
Applying Universal Formulas
For general IV push rate calculations, employ the universal formula: Infusion Rate = volume to infuse in mL / time of the infusion in hrs. Similarly, drip rates can be calculated using: Drip Rate = (volume to infuse in mL / time of infusion in min) x drop factor.
The choice of macrodrip or microdrip tubing influences the calculation, with microdrip commonly used for precise, minimal fluid amounts, and macrodrip for larger volumes. Microdrip tubing has a fixed drop factor of 60 gtt/mL, whereas macrodrip ranges from 10 to 20 gtt/mL based on tubing type.
Understanding these calculations ensures accurate and safe medication administration, optimizing patient outcomes.

Calculating IV Push Rate: Practical Examples
Example 1: Standard Dosage Calculation
To determine the IV push rate, first identify the total dosage required and the time frame for administration. For instance, if a doctor orders 400 mg of a medication to be administered over 4 minutes, calculate the rate by dividing the total dosage by the time. This gives a rate of 100 mg/min.
Example 2: Adjusting for Concentration
If the medication is supplied in a concentration of 200 mg per mL, and you need to deliver 400 mg over 4 minutes, determine the volume of medication to administer. Divide the ordered dose by the concentration: 400 mg / 200 mg/mL = 2 mL. Then, determine the rate of administration in mL per minute: 2 mL / 4 min = 0.5 mL/min.
Example 3: Incorporating Patient Weight
When calculating dosages based on patient weight, use the formula: dosage per kg x patient weight. For administering 0.5 mg/kg over 5 minutes to a 70 kg patient, calculate total dosage: 0.5 mg/kg x 70 kg = 35 mg. If the concentration is 10 mg/mL, divide total dosage by concentration: 35 mg / 10 mg/mL = 3.5 mL. Hence, the rate is 3.5 mL / 5 min = 0.7 mL/min.
Example 4: Infusion Time Adjustment
For an order to administer a 500 mg medication over 6 minutes, where the available concentration is 250 mg/2 mL, compute the required volume: 500 mg / (250 mg/2 mL) = 4 mL. Then, calculate the IV push rate: 4 mL / 6 min = 0.67 mL/min.
Example 5: Multiple Doses
Handling multiple doses involves calculating each dose separately and then their rates. For instance, if administering two medications together over the same period, calculate each medication’s rate using their respective concentrations and required volumes. If Med A needs 1 mL over 2 minutes and Med B needs 2 mL over 2 minutes, then administer Med A at 0.5 mL/min and Med B at 1 mL/min.
