Abstract
An infusion pump and method of operating an infusion pump in which the user of the infusion pump is prompted to input a number of infusion parameters, which include a dose mode, a drug dose, a drug amount, and a drug volume. After the parameters are input by the user, the infusion pump automatically calculates an infusion rate corresponding to the desired drug dose input by the user. The infusion pump, which includes a fluid pump, may round the calculated infusion rate to conform it to a flow rate which the fluid pump can deliver. If the infusion rate is rounded, the infusion pump calculates the actual drug dose from the rounded infusion rate and displays the actual dose on a visual display to allow the user of the infusion pump to determine how much the actual dose varies from the intended dose input by the user. After the actual dose is determined, the infusion pump continuously infuses the patient with the drug at the displayed infusion rate.
