2)Volume delivered is decreased.
3)Inspiration continues until volume is delivered.
4)Pressure is held and the breath is volume cycled.

The maximum pressure limit is a safety mechanism used during volume ventilation to avoid excessive pressure in the lungs.When the pressure measured by the ventilator reaches the maximum pressure limit inspiration ends.This means that the inspiratory time will be decreased and the volume delivered will be less than the set volume.Therefore,reaching maximum pressure limit causes the delivered breath to be pressure cycled.
