Answer to Question 1

ANS: D
The occlusion alarm activates when the airway pressure remains +15 cm H2O above the positive end-expiratory pressure setting for 3 seconds after exhalation has begun or at the end of exhala-tion, whichever comes first. This could occur when a patient bites the endotracheal tube because biting the tube can keep the pressure elevated for long periods.

Answer to Question 2

ANS: A
The pNeuton operates normally up to an altitude of 15,000 feet. Altitude does not affect pressure settings.
