The volume curve on a volume-time scalar graphic is consistently dropping below the baseline during exhalation on a mechanical ventilator. "Active exhalation" is suspected as the cause in the drop of the volume curve. Explain what is active exhalation and how it can be fixed.
The following spirogram shows a person's respiratory volumes as measured by a spirometer. The tracing began with resting, unforced breathing for the first 25 seconds, then forced breathing to measure vital capacities.

After finishing last in the gymnastics competition (they had to cut him free from the rings), it is now time for synchronised swimming. In order to be able to breathe under water, Marco has snuck in a balloon which he will breathe in and out of while submerged. Consider how the following parameters will change over time as he continues to re-breathe from the balloon. Ignore the pressure effects of the water on Marco and the balloon.
