Quizplus · Accepted Answer

The pressure-time waveform is raised from the zero line; this means that there is positive end-expiratory pressure.The flat pressure wave is indicative of pressure-limited breaths.The higher level represents the ventilator pressure-limited breath,and the lower level waveform represents the pressure-supported breaths.
