In brief: Increased lung use

The lung is a structure with many chambers.
If more of the chambers participate in breathing, more oxygen can be extracted from a breath. Assisted ventilation attempts to increase depth of breathing or pressure of air movement to involve more chambers in the process. If not, shallow breathing under lesser pressure is not doing the needed work.
