What is an IV Cannula?

An intravenous (IV) cannula, also known as an IV catheter, is a flexible tube inserted into a vein to deliver medication, fluids, or collect blood samples. They are widely used in healthcare settings and are crucial for administering treatments and monitoring patients. IV cannulas come in different sizes and materials, and their selection depends on various factors such as the patient’s age, medical condition, and the intended purpose.

The Importance of IV Cannulas

IV cannulas play a vital role in medical care, facilitating the administration of medications directly into the bloodstream. They allow for rapid delivery of fluids, blood products, and life-saving medications when immediate action is required. Additionally, IV cannulas are used for drawing blood samples for diagnostic purposes and monitoring a patient’s condition.
