Answer to Question 1

ANS: A
A. Correct response: A Level 1 event describes immediate life-threatening consequences to a ventilator malfunction. The expectation for a Level 1 alarm is that it will warn of every event in time for prompt corrections.
B. Incorrect response: A Level 2 event is a ventilator malfunction that is not immediately life threatening to the patient.
C. Incorrect response: A Level 3 event is a patient event affecting the ventilator-patient interface.
D. Incorrect response: A Level 4 event is a patient event not affecting the ventilator-patient interface.

Answer to Question 2

ANS: D
A. Incorrect response: See explanation D.
B. Incorrect response: See explanation D.
C. Incorrect response: See explanation D.
D. Correct response:
By performing an expiratory pause (EP), the therapist will be able to measure the intrinsic PEEP. The applied PEEP will be observed and measured with every breath without the therapist having to conduct any special maneuvers. The difference between the measurement obtained as a result of the expiratory pause and the applied PEEP will equal the auto-PEEP.
