Infusion Rate Calculator
This calculator helps determine the correct infusion rate for medications or fluids. Accurate calculation is crucial for patient safety and effective treatment. It's important to always double-check calculations with a qualified healthcare professional.
Total Volume to Infuse (mL):
Total Infusion Time (hours):
Drop Factor (drops/mL):
(Common values: 10, 15, 20, 60)
Calculate Rate
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 = ""; // Clear previous results
if (isNaN(volume) || isNaN(time) || isNaN(dropFactor) || volume <= 0 || time <= 0 || dropFactor <= 0) {
resultDiv.innerHTML = "Please enter valid positive numbers for all fields.";
return;
}
// Calculate rate in mL/hour
var rateMLPerHour = volume / time;
// Calculate rate in drops/minute
var totalMinutes = time * 60;
var rateDropsPerMinute = (volume * dropFactor) / totalMinutes;
resultDiv.innerHTML = `
Infusion Rate (mL/hour): ${rateMLPerHour.toFixed(2)} mL/hour
Infusion Rate (drops/minute): ${rateDropsPerMinute.toFixed(2)} drops/minute
