This calculator helps healthcare professionals determine the correct drip rate (in drops per minute) for administering intravenous (IV) fluids. Accurate drip rate calculation is crucial for ensuring patients receive the prescribed medication dosage safely and effectively.
function calculateDripRate() {
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)) {
resultDiv.innerHTML = "Please enter valid numbers for all fields.";
return;
}
if (volume <= 0 || time <= 0 || dropFactor <= 0) {
resultDiv.innerHTML = "Please enter positive values for all fields.";
return;
}
// Total minutes for infusion
var totalMinutes = time * 60;
// Drip rate calculation: (Volume * Drop Factor) / Total Minutes
var dripRate = (volume * dropFactor) / totalMinutes;
// Display the result, rounded to two decimal places
resultDiv.innerHTML = "The calculated drip rate is: " + dripRate.toFixed(2) + " gtts/min";
