This reduction in airway size, together with pooled mucus and the weight placed on the ribcage, makes breathing more laboured with fewer deep breaths. This can lead to airways and small areas of lung tissue collapsing (atelectasis), which reduces the area available for gaseous exchange (Corcoran, 1981).
