1. What is the Infusion Rate Calculation?

The infusion rate calculation converts the prescribed fluid administration rate in milliliters per hour (mL/hr) to drops per minute (gtt/min) based on the specific drop factor of the infusion set.

2. How Does the Calculator Work?

The calculator uses the infusion rate formula:

Where:

• \( \text{Rate} \) — Fluid administration rate in milliliters per hour (mL/hr)
• \( \text{Drop Factor} \) — Number of drops per milliliter for the specific infusion set (gtt/mL)
• \( 60 \) — Conversion factor from hours to minutes

Explanation: The equation converts the hourly rate to minute rate while accounting for the specific drop factor of the infusion set being used.

3. Importance of Drop Rate Calculation

Details: Accurate drop rate calculation is essential for proper medication administration, ensuring patients receive the correct dosage over the prescribed time period.

4. Using the Calculator

Tips: Enter the prescribed rate in mL/hr and the drop factor specific to your infusion set. Common drop factors are 10, 15, or 20 gtt/mL depending on the set used.

5. Frequently Asked Questions (FAQ)

Q1: What are common drop factors?
A: Common drop factors are 10 gtt/mL (macrodrip), 15 gtt/mL, or 20 gtt/mL for standard sets, and 60 gtt/mL for microdrip sets.

Q2: How do I know which drop factor to use?
A: The drop factor is printed on the packaging of the IV administration set. Always verify before calculating.

Q3: Why is the drop rate important?
A: It ensures accurate medication delivery and helps prevent under- or over-administration of fluids and medications.

Q4: How often should drop rates be checked?
A: Drop rates should be checked at least hourly or according to institutional policy to ensure accurate delivery.

Q5: What factors can affect drop rate accuracy?
A: Factors include IV catheter patency, patient movement, height of IV bag, and use of infusion pumps.
