Quizplus · Accepted Answer

To decrease tidal volume without altering inspiratory time on a BirdMark 7A ventilator during IPPB therapy, you would decrease the pressure (which directly reduces the volume of air pushed into the lungs) and decrease the flow rate (which reduces the speed at which air is delivered, thus reducing volume). Both adjustments lead to a decrease in tidal volume without changing the duration of inspiration.
