Read on to learn more about exactly how big each gauge of IV catheter is, what maximum flow rate it has, and the average lengths for each kind of catheter, as well as main uses of ...
By convention, peripheral IV catheters are sized in gauge, and central venous catheters (CVCs) are sized in French. This table compares French sizing to gauges for catheters with flow rates.
Catheter IV Size dictates flow rate. Shorter catheters of the same gauge will run faster than longer ones. CATHETER SPECIFIC TERMS. Needle Gauge: The gauge refers to the outer diameter of the needle. Needles are routinely available in a variety of gauge sizes, including 18, 21, 23, and 25 gauge.
