On inspecting a volume-pressure curve of the lungs and thorax, an increase in the mechanical work of breathing above normal would always be indicated by which of the following?

Question

Quizplus · Accepted Answer

An increase in mechanical work of breathing would indicate an increase in the effort needed to move air in and out of the lungs. This would result in an increase in the area of the volume-pressure curve as the thoracic and lung volumes would need to change to produce the same pressure. The other choices do not necessarily indicate changes in effort or work of breathing.
