I.V CANNULA

Description

An IV (Intravenous) cannula is a small, flexible tube inserted into a vein to provide venous access for administering fluids, medications, and other treatments directly into the bloodstream. Here are some key points about IV cannulas:

1. Types:
   • Peripheral IV Cannula: Commonly used for short-term treatments, such as in emergency or surgical settings. It is typically inserted into veins in the forearm or hand.
   • Central Line IV Cannula: Used for long-term treatments, such as chemotherapy or parenteral nutrition. It is inserted into larger veins, such as the jugular or subclavian veins.
   • Midline Catheter: Less invasive than a central line, used for treatments lasting more than five days but less than a month. It is inserted into a large vein in the upper arm.
2. Sizes: IV cannulas come in various sizes, indicated by gauge (G). The larger the gauge number, the smaller the diameter of the cannula. Common sizes include:
   • 14G: Large diameter, used for rapid fluid administration.
   • 16G: Used for blood transfusions and rapid fluid administration.
   • 18G: Commonly used for blood transfusions and general IV therapy.
   • 20G: Suitable for most IV therapies.
   • 22G: Used for pediatric and elderly patients with smaller veins.
   • 24G: Used for neonates and very small veins.
