II. descending ramp
III. sinusoidal
IV. oscillating

Question

Quizplus · Accepted Answer

Ascending and descending ramps are common morphologies of volume output waveforms in mechanical ventilation, as the flow rate steadily increases or decreases to maintain a set tidal volume. Sinusoidal morphology is also common, especially in patients with obstructive lung disease, where the volume waveform may show a characteristic wave pattern. Oscillating morphology is not a common shape of volume output waveforms in mechanical ventilation.
