Answer to Question 1

ANS: C
Graph C shows two pressure-limited breaths at two different pressures. The higher pressure is the pressure-limited ventilator breath, and the lower pressure is the pressure-limited spontaneous breath (or pressure-supported breath). Graph A shows volume-controlled continuous mandatory ventilation, graph B shows airway pressure-release ventilation, and graph D shows vol-ume-controlled intermittent mandatory ventilation plus pressure support.

Answer to Question 2

ANS: C
Airway pressure-release ventilation provides two levels of continuous positive airway pressure and allows for spontaneous breathing at both levels. The ventilator is time triggered, pressure lim-ited, and time cycled. The low time is usually approximately 0.2 to 1 second.
