Comprehensive Guide To Intravenous Catheters: Size, Types, And Clinical Applications
IV catheter sizes are characterized by gauge (thickness), diameter (bore), and lumen size (inner space). Gauge inversely relates to size, with smaller gauges indicating larger catheters. Catheter length and positioning are crucial for optimal function, influencing depth of insertion and tip location. Different catheter materials vary in biocompatibility and durability. Types of catheters include central…
