Which attribute is associated with high flow nasal cannula tubing?

• A. Green tubing that is stiffer and heavier
• B. Blue tubing that is flexible
• C. Clear tubing that is thin
• D. Red tubing that is brittle

Answer: (A)

High flow nasal cannula tubing must carry much higher gas volumes without collapsing or kink­ing. To do that, the tubing is wide-bore and built to be stiffer and heavier so it maintains its shape and delivers a stable, humidified gas at high flow rates. The green, stiffer and heavier tubing fits this requirement, making it the correct attribute for HFNC. Flexible, thin, or brittle options wouldn’t hold up under the higher pressures and could kink, collapse, or crack, which would disrupt the delivery of the prescribed flow.
