What is a hospital IV used for?

Intravenous therapy or IV, is the method of delivering fluids, medications, or nutrients directly to the bloodstream through a cannula (a small tube) injected into the vein. IV therapy is used when rapid or sustained access to the venous system is needed, including:

- Administering medication: IV medications can be delivered directly to the bloodstream, ensuring rapid absorption and precise dosage. This route is often preferred for medications that need to be delivered quickly, such as antibiotics, pain relievers, or emergency treatments.

- Providing fluids: IV fluids can be used to restore hydration, correct electrolyte imbalances, or provide nutrition when patients cannot eat or drink adequately.

- Supporting vital functions: IVs allow prompt interventions in critical situations such as managing blood loss or replacing lost fluids in surgical or emergency situations.

- Monitoring hemodynamics: IV lines can be used to monitor blood pressure, central venous pressure (CVP), and administer fluids to control fluid balance in critically ill patients or those undergoing surgery.
