IV stands for intravenous, which refers to delivering fluids or medicines into a vein. It involves the administration of concentrated medications (diluted or undiluted). An IV line is a soft, flexible tube placed inside a vein, usually in the hand or arm. The IV is left in place so that the fluids and medicine directly go into the blood. Blood samples may also be taken with the tube.
Some of the characteristics of an IV therapy include:
- Administering a medication intravenously eliminates the process of drug absorption from the gut.
- Medications can be released at the desired rate in the blood.
- There is an immediate elevation of serum levels and high concentration of the drug in the vital organs, such as the heart, brain, and kidneys.
- Therapeutic effects occur quickly.
- Chances of side effects are also high.
An IV therapy involves the following:
- Inserting a needle that’s inside a thin tube through the skin into a vein.
- Once placed inside the vein, the needle is removed.
- The catheter is left in place and kept in place using tape to prevent it from moving or falling out.
- While IV lines are typically painless, the initial needle insertion can be painful.
When is an IV placed?
An intravenous (IV) should be placed
- When there’s an issue with the digestive system.

- To take medications that can’t be taken by mouth.

How long does an IV last?
An intravenous (IV) may last as long as 3 days. The IV line should be replaced
- After 3 days.
- When the old ones stop working or fall out.

Are there any risks from IV placement?
Usually, intravenous (IV) placement doesn’t cause any problems. Rarely, there might be some issues, including:

High Blood Pressure (Hypertension)
High blood pressure (hypertension) is a disease in which pressure within the arteries of the body is elevated. About 75 million people in the US have hypertension (1 in 3 adults), and only half of them are able to manage it. Many people do not know that they have high blood pressure because it often has no has no warning signs or symptoms.
Systolic and diastolic are the two readings in which blood pressure is measured. The American College of Cardiology released new guidelines for high blood pressure in 2017. The guidelines now state that blood normal blood pressure is 120/80 mmHg. If either one of those numbers is higher, you have high blood pressure.
The American Academy of Cardiology defines high blood pressure slightly differently. The AAC considers 130/80 mm Hg. or greater (either number) stage 1 hypertension. Stage 2 hypertension is considered 140/90 mm Hg. or greater.
