Quick read:

Infusion pumps are used to deliver fluids, nutrients or medication directly into a patient’s bloodstream while regulating the amount administered. Infusion pumps are able to provide calculated amounts of fluids, alert caregivers of obstructions in the catheter, and record the amount of fluid received.

Full story:

IV (infusion) pumps are a common and essential tool for caregivers in hospitals, doctor’s offices, outpatient surgery centers, and emergency service vehicles. In the most basic sense, an infusion pump is a device that helps to deliver fluids, nutrients or medication directly into the bloodstream while carefully regulating the amount administered.

Infusion pumps are a key component of intravenous (IV) therapy because of their ability to deliver fluids or medication in precise and calculated amounts tailored to each individual patient. This provides a huge advantage over manually administering fluids, a practice that can result in a patient not receiving the correct amount of drugs or fluid.

Along with controlling levels of fluid intake, infusion pumps have the ability to alert caregivers of potential issues like reduced flow or obstructions in the catheter. They also record the amount of fluid the patient has received and how long it took for the process to finish.

A registered nurse will place the IV bag on a pole near the patient to create downstream pressure that pushes the substance into the body. They’ll then program the rate and duration of IV fluid intake required for the person receiving IV therapy into the infusion pump.

The catheter tube that transports the IV fluid must first pass through the infusion pump. Inside that device are rollers that use pressure to regulate the rate the IV fluid enters the patient. Based on the information inputted by the caregiver, the pump’s rollers essentially “milk” the tubing to ensure the correct rate of fluid administration is achieved.
