An increase in the work of breathing can result in a marked increase in oxygen consumption. An increase in the work of breathing can result in a marked increase in oxygen consumption,not in partial pressure. An increase in the work of breathing can result in a marked increase in oxygen consumption; it may not lower CO₂. An increase in the work of breathing can result in a marked increase in oxygen consumption; it would not alter alveolar perfusion.
