This calculator helps you determine the flow rate in milliliters per hour (ml/hr) needed for a specific medication or fluid. This is commonly used in medical settings to ensure precise administration of intravenous (IV) fluids or medications.
function calculateFlowRate() {
var volume = parseFloat(document.getElementById("volume").value);
var timeHours = parseFloat(document.getElementById("timeHours").value);
var timeMinutes = parseFloat(document.getElementById("timeMinutes").value);
var totalTimeInHours = 0;
var isValid = true;
if (isNaN(volume) || volume 0) {
totalTimeInHours = timeHours;
} else if (!isNaN(timeMinutes) && timeMinutes > 0) {
totalTimeInHours = timeMinutes / 60;
} else {
document.getElementById("result").innerHTML = "Please enter a valid positive infusion time in either hours or minutes.";
isValid = false;
}
if (isValid) {
var flowRateMlh = volume / totalTimeInHours;
document.getElementById("result").innerHTML = "The calculated flow rate is: " + flowRateMlh.toFixed(2) + " ml/hr";
}
