Introduction

The use of technology to push fluids into a patient has evolved and expanded over time. Bottles of fluids used gravity flow to “drip” fluids into a patient. As technology expanded into health care, the bottles were replaced with plastic bags and gravity was no longer medically adequate. Electromechnical pumps are more reliable and provide constant monitoring of fluid delivery. In addition, the flexibility of some pumps has improved medication dosing and caloric delivery. Hospitals have come to depend on the use of technology to deliver fluids and medications to patients.

Infusion pumps

One of the most common pieces of equipment in the hospital, the infusion pump (also called intravenous pump, IVAC, and IV pump) delivers medication, blood, or fluid into the patient over a specific period of time at a particular rate. The name used may reflect brand names from the past, including IVAC. Many patients will be connected to several pumps delivering fluids to the patient through a vein (hence, the term “intravenous”). The pump ensures an accurate rate and, therefore, an exact dose.
