Answer to Question 1

ANS: D
Auto-PEEP is made visible on a pressure-time scalar with the use of an end-expiratory pause. Point A is not positive end-expiratory pressure because there are areas in the waveform that go down to zero.

Answer to Question 2

ANS: B
When a patient has auto-PEEP, the expiratory flow does not return to zero. A new inspiration begins before the patient has had time to exhale completely. As a result, air remains trapped in the lungs. A pressure-time curve shows auto-PEEP only when an expiratory pause is used.
