- Importance of Catheter Selection: - The catheter’s diameter and length are critical factors affecting the flow rate. - Shorter, wider catheters provide a higher flow rate, making them preferable for rapid resuscitation. - Diameter and Flow Rate: - A larger diameter increases flow rate, and this relationship is proportional to the fourth power. For instance, doubling the diameter results in a 16-fold increase in maximum flow rate. - Peripheral 16-gauge IVs can sometimes outtransfuse larger cent
