[2025-10-01T23:16:58.110464] [PI reasoning] **Evaluating IV Cannula Sizes**

I need to interpret a multiple-choice question about the preferred IV cannula color and size for massive hemorrhage in a young patient requiring large volume fluid resuscitation. The typical color codes show that 16G (Grey) is the largest option listed. Others include 18G (Green), 20G (Pink), and 22G (Blue). Massive transfusion ideally uses a 14-16G cannula, so the answer is Grey. I’ll need to search for guidelines recommending this.
