Quizplus · Accepted Answer

Increased residual lung volumes are because of air trapping in obstructive lung disease and cause a barrel chest.Increased pulmonary blood flow does not affect chest diameter.Increased expiratory flow rates would decrease air trapping rather than increase chest diameter.Obstructive lung disease does not involve decreased chest wall compliance.It is increased as a result of loss of alveoli and elastic tissue.
