Understanding Cannulas and Their Uses in Medical Procedures A cannula is a thin tube that is inserted into the body, usually into a vein or artery, for the purpose of administering medication or fluids, drawing blood samples, or monitoring various measurements within the body. Cannulas are commonly made out of plastic or rubber and come in various sizes depending on their intended use. Intravenous Cannula Also known as an IV cannula, this is one of the most common types. It is inserted into a vein to enable administration of fluids, medications, blood products, and nutrition directly into the circulatory system. IV cannulas come in different sizes depending on the vessel to be accessed. Get More Insights On Cannula https://articlescad.com/cannulas-the-essential-medical-devices-saving-lives-daily-236042.html
