What is flow rate in the context of infusion pumps?

In the context of infusion pumps, flow rate specifically refers to the rate at which the infusion pump delivers fluid to a patient. This measurement is critical in medical settings because it determines how quickly a particular fluid, such as medication or IV fluids, is administered into a patient's bloodstream.

The flow rate is usually expressed in milliliters per hour (mL/hr) or drops per minute (gtt/min), and it is fundamental for ensuring that patients receive the correct dosage of medications or fluids in a safe and timely manner. Accurate flow rate management helps in maintaining therapeutic drug levels and balancing fluid intake, which is particularly important in critical care, pediatrics, and various other clinical situations where precise dosing could have significant implications for patient outcomes.

Other options, such as the speed at which a patient walks, volume of blood a patient must have, or the amount of medication in a single dose, do not pertain to the functioning and purpose of infusion pumps, which focus solely on the fluid delivery aspects.
