1. What is Gtt Per Min Calculation?

The Gtt Per Min calculation determines the number of drops (gtt) of intravenous fluid that should be administered each minute based on the prescribed flow rate and the specific drop factor of the IV tubing.

2. How Does the Calculator Work?

The calculator uses the Gtt Per Min formula:

Where:

• \( \text{Flow Rate} \) — The prescribed rate of fluid administration in milliliters per minute
• \( \text{Drop Factor} \) — The number of drops per milliliter for the specific IV tubing being used

Explanation: The equation calculates how many drops need to fall in the drip chamber each minute to deliver the prescribed amount of fluid.

3. Importance of Gtt Per Min Calculation

Details: Accurate calculation of drops per minute is crucial for proper medication administration, fluid replacement therapy, and ensuring patients receive the correct dosage of IV medications and fluids.

4. Using the Calculator

Tips: Enter the flow rate in mL/min and the drop factor in gtt/mL (typically found on the IV tubing package). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

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

Q2: How do I convert mL/hr to mL/min?
A: Divide the mL/hr rate by 60 to get mL/min. For example, 120 mL/hr ÷ 60 = 2 mL/min.

Q3: Why is the drop factor important?
A: Different IV tubing delivers different sized drops. The drop factor accounts for these variations to ensure accurate administration.

Q4: How often should drops per minute be checked?
A: IV flow rates should be checked at least hourly or according to facility policy to ensure proper administration.

Q5: What factors can affect the actual drip rate?
A: Factors include IV bag height, tubing kinks, patient movement, vein pressure, and catheter patency.
