During time-limited ventilation, the I time is unchanged when the flow pattern is changed from constant flow to descending ramp flow. The same volume can only be maintained if the peak flow of the descending ramp flow is ____.

Question

Quizplus · Accepted Answer

When changing from a constant flow to a descending ramp flow while keeping the inspiratory time (I time) unchanged, the peak flow of the descending ramp flow must be increased to maintain the same volume. This is because the descending ramp flow starts at a higher peak and decreases over time, requiring a higher initial flow to deliver the same volume within the same time frame.
