IV Infusion Drip Rate Calculator

This calculator helps healthcare professionals determine the correct drip rate for intravenous (IV) infusions. Accurate calculation of drip rate is crucial for ensuring patients receive the prescribed medication dosage over the correct period. It takes into account the volume of fluid to be infused, the desired infusion time, and the calibration of the IV tubing (drops per milliliter).

Understanding the Components:

  • Total Volume (mL): The total amount of fluid that needs to be infused.
  • Infusion Time (hours): The total duration over which the fluid should be infused.
  • Drip Factor (gtts/mL): This is a constant provided by the manufacturer of the IV tubing. Common drip factors are 10 gtts/mL, 15 gtts/mL, 20 gtts/mL, and 60 gtts/mL (for burettes). Always check your specific tubing packaging for the correct drip factor.

The Formula: The formula used to calculate the drip rate in drops per minute is: Drip Rate (gtts/min) = (Total Volume (mL) × Drip Factor (gtts/mL)) / Infusion Time (minutes)









function calculateDripRate() { var totalVolume = parseFloat(document.getElementById("totalVolume").value); var infusionTimeHours = parseFloat(document.getElementById("infusionTimeHours").value); var dripFactor = parseFloat(document.getElementById("dripFactor").value); var resultDiv = document.getElementById("result"); if (isNaN(totalVolume) || isNaN(infusionTimeHours) || isNaN(dripFactor) || totalVolume <= 0 || infusionTimeHours <= 0 || dripFactor <= 0) { resultDiv.innerHTML = "Please enter valid positive numbers for all fields."; return; } var infusionTimeMinutes = infusionTimeHours * 60; var dripRate = (totalVolume * dripFactor) / infusionTimeMinutes; resultDiv.innerHTML = "

Calculated Drip Rate:

" + dripRate.toFixed(2) + " drops per minute (gtts/min)"; }
