Which Pleural Abnormality Involves a Site?

Tension pneumothorax – the site of pleural rupture acts as a one-way valve, permitting air to enter on inspiration but preventing its escape by closing up during expiration, so pressure builds up in the pleural space

Which pleural abnormality involves a site of rupture that allows airs to enter on inspiration but not escape during expiration?

A tension pneumothorax is caused by excessive pressure build up around the lung due to a breach in the lung surface which will admit air into the pleural cavity during inspiration but will not allow any air to escape during expiration.

Which pulmonary disorder causes alveolar dead space?

Lung Disease: Emphysema destroys alveolar tissue and leads to air trapping and decreased diffusion surface area, thereby increasing dead space volume. Acute Respiratory Distress Syndrome (ARDS) creates disturbances in the pulmonary microvasculature, theoretically increasing dead space.
