WebPhysiological dead space may be increased with lung disease, due to an increase in the alveolar component. The volume of air that participates in gas exchange because it is in contact with perfused alveoli is the alveolar ventilation (V ˙ A = V ˙ E − V ˙ D physiological).The alveolar ventilation is critical, as it determines the amount of air …

WebAlveolar septal departitioning with destruction of pulmonary capillaries results in enlargement of the air spaces distal to the terminal bronchioles and an increase in alveolar dead space, that is, alveoli that are ventilated but not perfused. Elastic fibers are also found in the alveolar septa. WebNov 1, 2014 · The combination of these 2 conditions secondary to severe alveolar and vascular damage results in increased pulmonary dead space. Moreover, pulmonary dead space is increased by shock states, systemic and pulmonary hypotension, and obstruction of pulmonary vessels (massive pulmonary embolus and microthrombosis).
