Which IV gauge is typically used for unstable patients requiring rapid transfusion?

• A. 14 gauge (large bore)
• B. 18 gauge
• C. 20-22 gauge
• D. 24 gauge

Answer: (A)

In unstable patients who need rapid transfusion, the goal is to deliver blood as quickly as possible. The key factor is the IV catheter size: a larger bore offers less resistance and allows a higher flow rate. That’s why a large-bore access, typically 14 gauge, is used for emergent transfusions—it's the fastest way to get blood products into circulation. Smaller gauges would impede that rapid infusion because they create more resistance, slowing the transfusion. If a 14 gauge isn’t available, a 16 gauge can be used, but the larger bore remains the best option for rapid administration.
