II.high frequencies of breathing
III.increased V_T

Question

Which of the following factors would tend to increase the elastic component of the work of breathing? I.decreased compliance of the lungs or thorax II.high frequencies of breathing III.increased V_T

Quizplus · Accepted Answer

Decreased compliance of the lungs or thorax would require more force to expand the lungs during inhalation, increasing the elastic component of the work of breathing. Increased resistance (V_T) in the airways would also increase the elastic component of breathing work. High frequencies of breathing may increase the work of breathing, but it is more related to increased resistance or dead space than to the elastic component. Therefore, options B and C are incorrect.
