Which color corresponds to Size 4 Supraglottic airway?

• A. Yellow
• B. Red
• C. Purple
• D. Blue

Answer: (B)

Color-coding helps you identify the correct size of a supraglottic airway at a glance. For the device used in this course, size 4 is marked red. This quick visual cue matters because it ensures you select a size that provides an adequate seal and proper ventilation without causing trauma. A size that's too small can leak and fail to ventilate, while a size that's too large can irritate or injure tissues and hinder placement. The red indication for size 4 allows rapid, accurate sizing under pressure, which is why it’s the best choice in this context. Always verify with the device’s sizing chart in your kit, but in TP-C materials, red corresponds to size 4.
