Understanding IV Bolus Rate Calculations

In clinical settings, an IV bolus (or "IV push") refers to the rapid administration of a medication dose. Calculating the correct rate is critical for patient safety, ensuring the medication is delivered within the therapeutic window without causing adverse reactions like speed shock or vein irritation.

The Three Pillars of Bolus Math

To accurately calculate an IV bolus, healthcare professionals must integrate three specific values:

1. The Patient Weight: Most medications are dosed based on body mass (mg/kg) to ensure individualized therapy.
2. Concentration: The amount of active drug (mg) per milliliter (mL) of fluid. This determines the physical volume to be injected.
3. Time Factor: Boluses are rarely "instant." They are typically pushed over 2 to 20 minutes depending on the drug's safety profile.

The Formulas Used

This calculator utilizes the following medical math equations:

• Total Dose (mg) = Weight (kg) × Ordered Dose (mg/kg)
• Total Volume (mL) = Total Dose (mg) ÷ Concentration (mg/mL)
• Infusion Rate (mL/hr) = (Total Volume ÷ Time in Minutes) × 60

Practical Example

Let's say a physician orders a 5 mg/kg dose of a drug for a patient weighing 80 kg. The drug is supplied in a concentration of 10 mg/mL, and it must be administered over 10 minutes.

• Total Dose: 80 kg × 5 mg/kg = 400 mg
• Total Volume: 400 mg ÷ 10 mg/mL = 40 mL
• Infusion Rate: (40 mL ÷ 10 min) × 60 = 240 mL/hr
