Question

If you needed to intubate through an LMA, where on the LMA would the ETT go through?

A) Cuff inflation valve
B) Pilot balloon
C) Lumen for ventilation
D) Drainage tube

Answer 1

To intubate through an LMA, the ETT goes through the lumen for ventilation. The other parts of the LMA, such as the inflation valve, pilot balloon, and drainage tube are not for ETT insertion.

Step-by-step explanation:

If you needed to intubate through a Laryngeal Mask Airway (LMA), the Endotracheal Tube (ETT) would go through the lumen for ventilation of the LMA. The LMA features various parts, but the correct pathway for intubation would be the main lumen which is designed for gas exchange. The cuff inflation valve, pilot balloon, and drainage tube have different functions and are not suitable for the passage of an ETT.
