What is the purpose of the additional side port (Murphy eye) on most modern endotracheal tubes?
a. Protect the airway against aspiration.
b. Help ascertain proper tube position.
c. Minimize mucosal trauma during insertion.
d. Ensure gas flow if the main port is blocked.
ANS: D
In addition to the beveled opening at the tip, there should be an additional side port or "Murphy eye," which ensures gas flow if the main port should become obstructed. The tube cuff is perma-nently bonded to the tube body. Inflation of the cuff seals off the lower airway, either for pro-tection from aspiration or to provide positive pressure ventilation.
