how to insert iv canulla

A nursing cannula is a slender, hollow tube typically made of flexible, medical-grade plastic or metal. It is designed to be inserted into a patient's vein, usually in the arm, hand, or other suitable location, to facilitate the intravenous delivery of fluids, medications, blood products, or other treatments. The cannula comes in various sizes, with the appropriate size selected based on the patient's age, medical condition, and the intended purpose of the intravenous therapy.
