Intravenous (IV) fluids such as colloids, crystalloids, blood products, and oxygen-carrying solutions, are chemically prepared solutions administered to the patient. They are tailored to the body’s needs and used to replace lost fluids, sugars, salts, fats, and other substances vital for the human body and/or to aid in the delivery of IV medications.
The IV-fluid bag has a medication injection port and administration set port. Both ports are on the bottom of the IV bag when it is held upright. The medication injection port permits the injection of medication into the fluid for use by a care provider. The administration set port receives the spike from the IV administration set (IV tubing).
