What is iv cannula?

     IV cannula, also known as an intravenous cannula or IV catheter, is a medical device used to administer medications, fluids, or nutrition directly into a vein. It is a small, flexible tube that is inserted into a vein in the arm, hand, or foot using a needle. Once the needle is removed, the cannula remains in the vein and is secured in place with a dressing. The IV cannula allows for quick and efficient access to the bloodstream and is commonly used in hospitals, clinics, and emergency medical settings. There are different sizes of IV cannulas available, ranging from small sizes for children to larger sizes for adults or patients requiring high-volume fluid administration.
