IV CANNULA TYPES AND USES

An intravenous cannula is a flexible tube that can be inserted into a patient’s body through the veins and is mostly used for administering medications and I.V. fluids as well as for taking blood samples. The sizes of intravenous cannula have different colour codes for different purposes. Cannula sizes mainly range from 14 to 24 gauge. The purpose, the condition of the patient, and the urgency at which intravenous fluid must be delivered determine which cannula sizes must be used. The smaller the gauge, the larger the diameter of the cannula and the faster the flow of fluid
