This calculator helps healthcare professionals and caregivers determine the correct rate at which an intravenous (IV) fluid should be administered to a patient. It calculates the number of fluid drops that should be delivered per minute based on the prescribed volume, the total infusion time, and the drop factor of the IV tubing.
Common drop factors are 10, 15, 20, 60 (for burettes).
function calculateInfusionRate() {
var volume = parseFloat(document.getElementById("volume").value);
var time = parseFloat(document.getElementById("time").value);
var dropFactor = parseFloat(document.getElementById("dropFactor").value);
var resultDiv = document.getElementById("result");

resultDiv.innerHTML = "Please enter valid positive numbers for all fields.";
return;
}
// Convert time from hours to minutes
var timeInMinutes = time * 60;
// Calculate the infusion rate in drops per minute
// Formula: (Total Volume in mL * Drop Factor) / Total Infusion Time in minutes
var dropsPerMinute = (volume * dropFactor) / timeInMinutes;
