What gauge and length needle is commonly used for chest decompression?

• A. 14 gauge 3.25" angio
• B. 16 gauge 1.5"
• C. 18 gauge 2.0"
• D. 20 gauge 2.0"

Answer: (A)

Chest decompression relies on a large-bore catheter to vent air quickly from a tension pneumothorax. A 14-gauge, 3.25-inch angio-catheter provides enough diameter for rapid air flow and a length long enough to reach the pleural space through the chest wall in most adults. The smaller gauges or shorter lengths in the other options may not reach the pleural space or allow sufficient drainage, making them less effective for emergent decompression.
