Answer to Question 1

ANS: A
Because the expiratory volume does not return to zero in these graphics, a leak is present in the patient-ventilator circuit. Increased airway resistance would show as a scooped-out expiratory flow on the flow-volume loop, which may not end before the next breath. Decreased lung com-pliance would show as a duck bill on the pressure-volume loop. Active exhalation would make the volume tracing drop below zero.

Answer to Question 2

ANS: B
The expiratory flow in this loop does not return to zero. This shows that auto-PEEP or intrinsic PEEP is present.
